Gumout Q&A – Sept 2015

Gumout question and answers.

Find below a comprehensive Q & A about all things Gumout

1. In the introduction, it was mentioned that dirty surfaces can hold moisture and cause rust. For internal panel surfaces, under-car and high wash areas, have you found that waxy or oily coatings perform better? What are Gumout’s offerings and how do they compare to the competition? Are there any concerns with rubber compatibility?

Gumout doesn’t have products for these areas you mention. However, for exterior prep we have some other brands that can do the job. Clean the surface using the appropriate cleaner for the vehicle surface, for example Black Magic® Car Wash, Black Magic® Wheel Cleaner, Black Magic® 2-in-1 Engine Shine. These products remove soils that may trap moisture and contribute to corrosion.

Step 2. To protect the surface use a quality wax containing hard natural wax such as carnauba or synthetic micronized waxes and detergent resistant silicones. This will form a barrier between the surface and moisture to help protect against rust and corrosion. Regular oils or silicone fluids will usually wash away more quickly when exposed to the weather.

Rubber compatibility is not a concern for damage, but most traditional car waxes contain polishing agents that leave a white residue on rubber, so avoid rubber.

2. Before winter do you recommend adding fuel stabilizer running for 10 mins then draining carb or leaving it full of the stabilized fuel?

We recommend a treatment of fuel stabilizer (Gumout® Multi-System Tune-Up) and leaving the fuel system full of fuel. Emptying the carb will usually leave fuel residue behind and the empty headspace will encourage evaporation and oxidation causing gum and varnish.

Sometimes your storage plans may change and you may want to take the vehicle out of hibernation or use your stored equipment. The easiest solution to this issue is always (throughout the year when it is used) treat the fuel used in seasonal equipment with stabilizer and complete fuel system cleaner. This way the system is consistently being cleaned and will be ready for storage at any time.

3. The Gumout Multi-System Tune Up claims to stabilize fuel. How long does it stabilize fuel? Would doubling the amount increase the “longevity” of the fuel?

While the exact length of time will vary depending on the specific fuel and storage conditions, on average our product will stabilize up to 12 months. Doubling the amount will increase the life of the fuel, but we cannot promise the fuel life will double.

We have run a test program that demonstrated treated fuel lasted well over double the life of untreated fuel. Another multi system additive competitor in a similar package actually reduced the life of the fuel to less than untreated in this same test. Yes, competitor-treated fuel was less stable than untreated. Visit the Multi-System Tune-Up science page on for more details.

4. Does the All-in-One also stabilize fuel? If so, would it be the same as the Multi-System Tune Up?

There are no anti-oxidants in All in One fuel therefore it will not stabilize fuel. Gumout Multi-System Tune Up will stabilize fuel and oil.

5. Do your fuel stabilizers work with E10 ethanol? I run E85 in my vehicle that is made for E85, which of your products will work with E85? Is a fuel system conditioner necessary while running E85?

Gumout® Multi-System Tune-Up will work with E0, E10 and E85. It contains a specially designed additive package that is soluble in all these types of fuel. All other Gumout® additives work in either E0 or E10, but may not dissolve properly in E85. We recommend using Gumout® Multi-System Tune-Up while running E85 to keep the fuel system clean.

Lower Viscosity Grades – Round 3

Round 3 BITOG Q&A: Lower VIscosity Grades
Sept 13th, 2015
Find below a comprehensive Q&A about all things Pennzoil

1. All this talk about thinner grades, some manufacturers are spec’ing thicker grades if you race and/or track your car. The current Corvette is one. GM specs 15W50. And as everyone knows, Ford specs 5W50 for it’s top of the line Mustang. Does Pennzoil plan on coming out with a 50 weight oil to compete with brands like Mobil 1?

Pennzoil offers a number of “thicker” grade products, examples being Pennzoil Platinum 5W-50 , Pennzoil Platinum Racing 10W-60 and Pennzoil GT Performance Racing 25W-50.

2. Why isn’t Pennzoil Gold Synthetic blend available in 5W-20? Does Pennzoil plan to make a thinner resource conserving high mileage oil to compete with GTX HM and Maxlife? Maybe Synthetic Blend?

Pennzoil Gold/Synthetic Blend is available in both 5W-20 and 0W-20.

3. Lower viscosity oils are generally for the purpose of improving fuel economy. Engine wear and durability do not seem to be an issue with modern 0W-20 viscosity grades and the engines that call for them, but it is still a common question among enthusiasts. Balancing low viscosity/engine wear. My question is whether it would be beneficial to run a 5W-30 for a bit of added protection if one pushes the engine a bit harder than expected, (in a vehicle that calls for a 20 grade)?

In a vehicle calling for a 20 grade oil it would naturally be recommended to run a 20 grade oil, however your question raises a good point, is it beneficial to still choose a thicker grade of oil for added protection? Comparing a 20 and 30 grade oil from the same Brand and Tier it is likely they will share a very similar additive package and teat rate and therefore offer the same level of protection derived from the performance additives present in the oil, therefore differences in protection will be due to the higher oil film thickness potentially offered by the difference between a the 20 and 30 grade. Unless you are operating significantly harder than a normal duty cycle it is unlikely you will see any benefit. Significantly harder duty might mean a very high proportion of long idle time followed by sudden high speed accelerations (common in police duty as an example) or a harsh environment with lots of sand and dust (abrasive agents). In summary you’d need to push an engine a lot harder to see a benefit.

4. Switching from a 5W-20 to 0W-20 how much would I save in a 20 mpg vehicle during a 10K OCI.

Good question because it is so hard to answer, there are simply many factors at play; examples of significant ones being – your driving style, the engine design in question, the duty cycle, fuel quality. From a monetary point of view of course the price of fuel has to be considered in any calculation and this is a variable in itself! There are numerous industry standard tests, all of which will give you different answers to your question. As a best guesstimate potential saving would lie between 0.1 and 0.5%. Shell offers a range of fuel saving tips to help maximize fuel economy which individual drivers can employ and it would be recommended to try these first until your reach a natural oil change interval, at which point switching to an appropriate fuel economy grade oil will also help.

5. Does Pennzoil plan on using any type of titanium additives?

Pennzoil is constantly evaluating new additive technologies that we develop or are offered, as yet we have not seen sufficient end benefit in Titanium additives to consider using them in our products.

6. We have seen that some lighter oils, comparing with others at the same stated weights, exhibit thicker or thinner viscosity than the norm for that weight. What are the sources of the this variability including, but not limited to, manufacturing tolerances?

I’ll interpret it to this question to be asking about the viscosity grade windows as specified in SAE J300. Weights , or viscosity grades, as defined in SAE J300 as ranges of viscosity and hence for a given grade or weight there are a range of viscosities, thicker or thinner than the middle point of the grade; this of course being reflected in products in the marketplace. Critical factors driving where a product falls in a weight or grade being the base oil choice, the viscosity modifier choice, the performance additive package. Manufacturing tolerance also play a role but not as large as the ones I have cited.

7. This variability raises issues especially as we transition to lighter weights for if the variability is on the lighter side then sufficient protection will be compromised. How does Pennzoil intend to provide appropriate quality control to see that this does not happen?

The SAE J300 grade or weight structure is such that there are multiple properties required to define a grade or weight. Pennzoil checks these properties on each and every batch of Pennzoil manufactured and has put in place blend controls reflecting the tolerances of production, measurement and specification (SAE J300).

8. Further, this variability, if on the heavier side, could be exploited to call a given oil a 20 wt. for instance but in actuality it might be a 25 or 30 wt or ? How will the “bandwidth” of individual grades be policed especially if certification is reached by read-across or via modeled means?

AE J300 defines grade (or weight) and is a definitive scale, i.e. it has been designed that such that products can only be quoted against one grade or weight. If properly followed, no the SAE system cannot be exploited as is suggested. At Pennzoil , as per the answer above, we quality check each batch of product rather than rely on read across or models in confirming the SAE grade (or weight ) of our products.

9. Finally, do you foresee that, as the engine manufacturers resort to more complex and effective internal coating processes-surface preparations that your efforts at the lighter weights will indeed be made easier? Could you enlighten us on what processes may be in prospect and what impact it will have on your efforts?

Certainly engine manufacturers are increasingly looking at coating engine parts in order to reduce friction (for improved fuel economy) and enhance wear protection (for long term durability). A very common coating which has made its way over from motorsport engines is DLC – Diamond Like Coating – which has both frictional and wear benefits. Another approach is to alter the surface texture on the nanometer scale to aid the oil in supporting a film and hence again improve friction and wear performance.

10. I achieve no worse MPG with Pennzoil Ultra 5W-30 compared to the specified 5W-20 by Chrysler… So what exactly is the supposed benefit of the 5W-20 & 0W-20 viscosity oils?

Delighted to hear of your experience. In general a very wide body of data supports the conclusion that lower viscosity oils offer better fuel economy, however as per the answer to (4) for the individual driver the benefits vary due to the many variables at play.

11. What are the differences between 0W-20 and 5W-20 when dealing with an extended drain oil?

Oil life or drain interval, is not dictated by SAE grade (or weight), you should observe and experience the same oil drain interval for a 0W-20 as a 5W-20.

12. I would think that the 0W-20 would have more viscosity modifiers that may flash/burn/shear off turning the oil into something more like a 5W-20 in say 5k miles. Is that true or does a 0W-20 typically hold it’s specs in a well running engine over a 10K OCI?

All reputable motor oils are required to stay in grade over the OEM specified service interval (oil drain interval) as defined in your owners handbook and there are industry standard tests and oil should meet in order to demonstrate this property.

13. I am old. During my life time 30 and 40 weight motor oils have been the standard during most of it. During the last decade or so 20 weight motor oil has become a standard. From what I have read, Corporate Average Fuel Economy reporting has created the 20 weight standard because of less drag on internal engine components. If you had a crystal ball, what is going to be the next standard oil weight?

The SAE recently approved the definition of 16 weight oils and the API has introduced them into their licensable specs, you can expect this to be the next “new” standard weight of oil on the market.

14. MPG wise, how much fuel can I really save by using your full synthetic over just Shell conventional?

This is a very broad question since you don’t specify whether you’d like to use the same grade or weight of synthetic vs. conventional. In general synthetic oils have been introduced to enable lower weights or grades of motor oils to be used in modern engines. These lower grades or weights enable a number of technologies aimed at delivering fuel economy, so you’re not just talking about the fuel economy of the oil but the fuel economy of the overall engine/vehicle.

Looking at readily available figures you’ll see vehicles offering marked improvements in fuel economy over the last decade with this trend set to continue.

Many, if not the majority, of vehicles coming onto the road today only recommend the use of synthetic oils for these hardware related reasons. As per previous answers there are also issues of driving style and operating duty to consider in the individual case. Without knowing more background it’s hard to give you a figure but it could be in the region of 2%.

15. I like to use thinner grades of full synthetic to thin out heavier grades of conventional or synthetic motor oils. I’m currently running a blended mix of M1, 15W-50 and M1 0W-20, 3 quarts of each until the cold of winter arrives. Once the cold of winter arrives, I’ll be using 1 Gallon of Shell Rotella T6 and 2 quarts of Formula Shell full synthetic 5W-30 until June. I’ll keep the same M1 extended performance filter on for 2 runs along with a filter magnet attached to the filter. Would running Pennzoil Ultra or Pennzoil Platinum in a 5W-30 be more beneficial year round rather than blended mixes?

You’re clearly looking to take a great deal of care of your engine and have thought a lot about your choices of oil. Whilst blending together oils may give you the expected physical properties (e.g. viscosity) the performance of mixtures of performance additive packages is much harder to predict, I’m afraid chemistry is much less predictable than physics!

I would recommend using a single product and the two products you suggest would be excellent choices. As another point to consider, running a single brand oil as oppose to mixes will put you in a better position were you to experience an issue and to wish to make a claim under either an OEM or Oil Warranty scheme.

16. I’m interested in making a custom blend for my vehicles. Preferentially starting with Rotella T6 5W-40, as it’s in the family, but wanting something a bit closer to 5W-30. Rotella as it’s in the family, and a strong oil, but if needed, Platinum Euro 5W-40 could be considered as a starting point. I would like to blend it down to a 5W-30 using Platinum 5W-20, so that I will end up with a 5W-30 with a little more anti-wear additive than the typical 5W-30. Are there any problems doing this, and will the results be as I expect them to be?

The physical results may be very much as you expect i.e. viscosity is likely to be predictable following well known physical laws however the chemical effects are highly unpredictable. Wear performance is not dictated solely by the amount of wear protecting additives in an oil, the efficacy (effectiveness) of the additives must also be considered. Efficacy can be negatively impacted by changing the balance of a formulation package. The approach you suggest could conceivably result in poorer performance, I would recommend choosing a single tier of product, and Pennzoil Platinum has been designed to offer complete protection including unsurpassed wear performance.

17.  The new GM trucks spec 0W-20 oil. How does this thin grade hold up when towing maximum loads? Would thicker be better under these extreme conditions?

GM recommends 0W-20 for this engine and has conducted testing to validate performance.  Additionally other engine features like cam phasing depend on the proper and validated viscosity to maximize performance.  In this case, we recommend to use the oil recommended by the manufacturer. 

18.     What are the different antiwear additives, or combinations of same, that will be able to withstand the 200,000 psi squeeze-out you mention in the valve train that will not affect catalytic life span or other parameter like deposits? We have seen some transition to titanium. What others, or combinations of others, are possible? This is not meant to require a proprietary data answer.

The antiwear technology is of course proprietary, but suffice it to say that the important thing to focus on is the overall performance of the oil.  This is done by conducting the engine tests dictated by industry and OEM standards, on our own proprietary testing.  Rest assured that every grade of Pennzoil meets the requirements of antiwear, oxidation protection, viscosity shear, required by the stringent industry and OEM tests.

19. With GF-6B (SAE 16) oils having a minimum HSTS of 2.3 this will allow for a thinner protective film. I found this on Lubrizol’s website, “While it is generally accepted that lower viscosity brings an improvement in fuel economy performance, it can have a negative impact on durability; the protective oil film is less robust, or under the most extreme loading conditions, non-existent”. The word “non-existent” is pretty scary in terms of engine longevity.

a. In order to protect engines using SAE 16 oil under high load/stress, also with the abrasive soot of GDI, what can you tell us about the additive packs in your new GF-6B oils?

b. What new technology will be in the additive packs?

c. Will GF-6B be able to meet the same wear requirements of GF-6A (i.e. 0w-20)?

d. How will engines be designed differently to successfully use SAE 16 oil?

e. Will there be any GF-6B oils that are backwards compatible to GF-5 or GF-6A?

f. Will there be more than one Pennzoil viscosity grade with GF-6B other than 0w-16, such as 5w-16 or 10w-16?

A. OEMs will already be testing new engine designs at minimum HTHS below 2.3 , you could expect engine designs capable of operating on an HTHS of 2.0 to be under development and testing at the moment. These designs will place more stringent demands on the lubricant to ensure both fuel economy and durability issues are addressed. Shell is actively partnering with OEMs to co-engineer solutions as these technologies come to market. There are numerous technologies OEMs are looking to introduce into engines that might coincide with the period during which 0W-16 oils become prevalent in the market, technologies such as changes in bearing materials and dimensions, changes in valve train design, changes in coatings and texturing of surfaces to name few commonly talked about.

The new products being developed will rely both on optimizing the additive and base oil technologies together to address challenges such as GDI soot. Different technical solutions will be developed so it is unlikely there is one single solution we will reflect back on. Soot has been successfully addressed in other lubricant areas through a knowledge of how to handle soot in the oil and how to provide durable protection via the anti-wear film.

At the moment the industry strategy is to deliver GF-6B oils that will not be backwards compatible to GF-5 or GF-6A, this is to avoid mis-application of the new GF-6B products.

Valve Train and Timing Chain Wear – Round 2

Pennzoil question and answers.
Sept 8th, 2015
Find below a comprehensive Q&A about all things Pennzoil

1. What do you consider the major source of oil shear in an engine?

As you know, mechanical shearing occurs at several common locations within an engine and it can differ from engine to engine based on the hardware design, In my opinion, most of the shearing occurs in the valve train and the timing chain/gears. Even with this somewhat definitive answer, the answer would also vary for example from a single overhead cam engine with roller followers compared to a vee-block engine with four cams and variable valve actuation. Of course, the piston rings spreading oil into the honing marks can contribute to shear. The oil pump and distributor gear (if equipped) could contribute to shear and the list goes on.

2. Does the length of timing chain have any relevancy to shearing of oil?

Intriguing question but I would think the answer is no if you are asking about a straight swap. The crankshaft and cam(s) would rotate at the same relative speeds regardless of the chain length and thus the mechanical friction would be similar. However, you could argue that a longer chain would have an additional tensioner or perhaps an idler that would cause more shearing and you could also argue that more links in the chain have more rollers and pivot points that would directionally shear more oil.

3. Do twin cams vs Sohc and contribute to more shear?

Be it one cam or four cams, they would all spin at the same relative speed so think about it as one shear machine versus multiple. More sprockets mean more chances for shear. More cam lobes mean more chances for shear.

4. As fuel economy standards increase, resulting in the push toward lower viscosities (thinner oil films), and greater use of Direct Injection with particulate generation problems, what motor oil formulation changes will allow for lowering wear & friction in cams, lobes, and timing chain pins? As in, for GF-6 and dexos-2016.

If I may, please let me answer this in pieces. Formulators of course watch volatility more and more closely as the viscosity gets lower. They need to watch NOACK volatility results. They need to understand how the volatility of the base oils and the volatility of additives contribute to component durability and they also need to be aware of oil consumption.

You are all aware of anti-wear additives that work to protect metal surfaces by creating a sacrificial chemical coating on the metal and you also know that friction modifiers work to make the oil more slippery by attaching to the metal surface to influence the static and/or dynamic friction. Now consider the possibility that an engine manufacturer employs a coating like DLC or switches to anodized hardware. Different additives may be competing for the same metal surface or may need to be modified if the traditional metallurgy has changed. Just as those hardware changes will influence the evolution of the engine, our formulators must push the oil formulations to evolve.

Similarly, variable valve actuators may need both wear protection and friction modifiers to operate properly and operate fast enough to respond to the immediate demands of the PCM or else a trouble code could be set.

Finally, particulates need to be properly dispersed so they will not block delicate clearances or passageways, so they do not thicken the overall viscosity and so they can be properly filtered out in the filter before causing abrasive wear.

5. Has Pennzoil done ASTM WK49675 or similar testing with an older ASTM timing chain wear standard on Pennzoil motor oils? IF so, can you share the results of those tests?

The ASTM WK49675 test is still under industry development. Hence, we do not have any official data to share.

6. Can you share the results of the valve train wear tests the Pennzoil motor oils have been subjected to?

For the Sequence IVA test, our Pennzoil Platinum products result in less than 20 µm, which means that according to the industry precision data for that test our result is unsurpassed.

7. How much can motor oil really affect the wear on the valve train? Timing chain?

a. In the valve train between the cam lobe and its follower, the valve spring can push those two pieces together so hard and on such a small area of contact that the local pressures could calculate to 200,000 psi. This is enough to squeeze the oil (conventional or synthetic) out of the way. So oil formulators typically use wear protection additives that form a sacrificial chemical coating on the cam lobes and followers that can withstand those extreme pressures.

b. In variable valve train actuators, detergents and dispersants must keep the actuators clean – the tolerances here are extremely tight and the actuators must precisely alter the cam phasing upon demand from the ECM. Friction modifiers are used to help keep the internal components of the actuators moving freely without stick-slip. To reduce air entrainment in the oil and to ensure the right viscosity at the right temperature, oil formulators carefully select quality base stocks and incorporate anti-foaming or air release additives.

c. For timing chains, in addition to the need for correct wear protection additives and friction modifiers, the oil formulators also watch the dispersants in the oil quite closely. The fear is that without a suitable dispersant, soot and carbon in the oil could collect inside the pins of the chain and create wear or limit movement that would result in the chain’s effective length changing. If the chain’s effective length changes even slightly, it can be sensed by the ECM and create problems.

8. On your website, there is an oil selector page…8&brand=121 You don’t yet show a recommendation for my vehicle, a 2016 Subaru Forester 2.5i Limited with the normally-aspirated FB25 engine. Likely because this model year of the vehicle has only recently gone on sale. However, for the MY 2015 version of my vehicle with the same engine, this oil selector page generates only one recommendation, the Pennzoil Platinum 0w-20. Notably, the Pennzoil Platinum Ultra 0w-20 is NOT shown as a recommendation. Is this an oversight, or is there something in or not in the Ultra that makes its use not suitable for the FB25 engine?

The 2016 Subaru Forester 2.5i owner’s manual states “0W-20 synthetic oil is the required oil for optimum engine performance and protection. Conventional oil may be used if synthetic oil is unavailable. If 0W-20 synthetic oil is not available, 5W-30 or 5W-40 conventional oil may be used if replenishment is needed but should be changed to 0W-20 synthetic oil at the next oil change”. Our Pennzoil Platinum and Pennzoil Ultra Platinum 0W-20 meets Subaru motor oil requirements. I will pass along the concern about the listing in the website to the appropriate people. Thanks for catching that.

9. From your research regarding valve train and timing chain wear, has synthetic oil been proven to provide better wear protection vs. using conventional oil in the same application?

I view it as a total package. It is possible to use synthetic base stocks and yet make a poor oil when it comes to wear protection. But the formulators here at Pennzoil use quality base stocks along with the right wear protection packages and other additives to yield final synthetic formulations that perform great in the industry standard wear test, they perform great in the Chrysler SRTs and our formulators can also make oils that perform great in race engines.

10. How has motor oil technology changed to adapt to advances in newer valve train/timing chains?

Though you could argue that additives and base oils have been around for decades, this is an industry that keeps innovating for new chemistry, for new ways to rebalance existing additives and base oils, and for new ways to accommodate new hardware or new industry regulations. One example is the “zinc” wear protection additive. Some could argue the basic molecules have existed for decades. Others with performance, custom engines would want to know how much additive is needed for their engine versus a newer stock engine with roller followers. Yet others could argue that low volatility wear protection additives are an interesting tweak on the historic molecules to help prevent the additive from evaporating and turning into ash.

Complete Protection & Debunking Myths

August 28, 2015

I feel cars that are stored inside a garage and are driven infrequently (including classic hot rods & antiques) rarely need an oil change and can go many years with oil left in the sump, especially with synthetic lubricants. The myth is “change your oil once a year, regardless of miles”. Your thoughts on this?

Yes, you should change your motor oil at least once a year even if the vehicle is in storage and rarely driven. If you drive the vehicle once and then allow the vehicle to sit for a year without an oil change, you are allowing the byproducts from combustion and acids to sit, agglomerate, and possibly break down engine materials. For more information on classic car storage, check out the Hagerty Insurance website.

Can you help us better understand how the selection of base stocks may impact an oil’s suitability for and impact upon direct injection engines? Often it has been noted that parameters such an NOACK and specific additive chemistries may impact valve deposits and other DI-related problems. Does a GTL lube, some of which have been shown to have very low NOACK values per the SOPUS PDSs offer superior benefit in DI engines, as compared to lubricants formulated with a bias towards use of PAO, POE or other basestocks? If so, why? Is it due to the attractive NOACK values, or are there other characteristics related to fuel dilution or other phenomena that play in?

Yes, direct injection engines often run hotter than port injection engines. Thus said, choosing base oil with excellent high temperature properties provides better protection and performance. Low volatility and good oxidation stability are two key high temperature properties found in high quality base oil. NOACK is an industry test that measures volatility. Low volatility means the oil is less likely to vaporize, or evaporate, at high heat. Good oxidation stability means the oil is less like to break down when exposed to oxygen and high heat, leading to fewer deposits. Formulating the motor oil with high quality detergents and dispersants also helps reduce deposits and keep byproducts from combustion from agglomerating to form sludge.

What does Complete Protection mean? Isn’t that what API licensing provides?

API (American Petroleum Institute) licensing does not mean the motor oil provides complete protection. For example, motor oil that has “API SA” printed on the back of the bottle is not suitable for use in engines manufactured after 1930. The latest industry motor oil specification is API SN/ILSAC GF-5 – however, this is only the minimum industry standard and there is a lot of room for differentiation. Also, some manufacturers make recommendations outside of the API system.

Pennzoil Synthetics provide complete engine protection without compromise. This means we are not compromising any area. Complete protection includes cleaner pistons, better fuel economy, horsepower protection, unsurpassed wear protection, and excellent performance in extreme temperatures.

How does motor oil impact horsepower?

Horsepower is the measured power output of an engine. This is based on the mechanical design of an engine and using proper motor oil helps maintain horsepower. Engine deposits or using a viscosity grade that is too thick can decrease engine efficiency.

What temperatures are you referring to when referencing extreme temperature protection? Can an oil really protect at both ends of the extreme in one oil change?

Yes! Pennzoil Synthetics have excellent performance in extreme temperatures. Extreme temperature performance refers to both an extremely cold day, like -40°F, and extreme hot spots inside your engine – like the turbocharger shaft or piston rings, which can reach over 400°F. Average engine operating temperature is 212°F with the combustion temperatures up to 2,500°F.

Hybrid vehicles have a lot more start-stop conditions than a traditional engine. While many of the start events are likely with a good film of oil, ready pumpable lubricant, and warm engine, the nuances of cranking and the first fires at startup may have effect upon fuel dilution, cylinder wash-down, etc. What lubricants might be best suited for these kinds of operations, and why?

The best suited lubricant is the one that meets the manufacturer’s recommended viscosity grade and engine oil specification. Because hybrid vehicles endure frequent stop-and-go driving, I would recommend using full synthetic motor oil.

Would you consider Pennzoil Platinum to be a higher quality product than Mobil 1?

Pennzoil Platinum and Pennzoil Ultra Platinum outperform Mobil 1 products in several industry standard tests. For example, Pennzoil Ultra Platinum keeps pistons up to 25% cleaner than Mobil 1 and Pennzoil Platinum keeps pistons up to 8% cleaner than Mobil 1, based on Sequence IIIG engine tests. See the proof here:

We need better access to Pennzoil Ultra Platinum

We’re always looking to get into more stores across North America so we suggest you ask your local auto body shop to request some Pennzoil Ultra Platinum from their regional Pennzoil distributor. In the meantime, Pennzoil Ultra Platinum can also be purchased online from Amazon here:

To start, great videos on YouTube! I am currently using a few final quarts of Royal Purple for my passenger vehicles (TL & Accord). In the last three weeks I have purchased 50 quarts (10 – 5 quart jugs) of Pennzoil Platinum 0W-20 for the reasons you’ve outlined in your videos, such as Pennzoil Platinum’s ability to clean pistons, lubricate and just as important its ability to protect from engine wear.

Thank You!!

( Supplemental questions below ):

a. My questions are… How long is the shelf life for Pennzoil Platinum 0W20 if it is stored in my garage, knowing that it will take me 3-4 years to use this oil?

Pennzoil Platinum Full Synthetic motor oils can have a shelf-life of up to four years if stored properly.

b. What is your oil change interval recommendation (total miles per OCI)? Both cars are ran 50/50 highway and city driving and I live in California.

Always follow the vehicle owner’s manual to determine the correct oil change interval. I think both vehicles have an oil life indicator you can follow.

c. Last question…why Pennzoil Platinum with PurePlus Technology over Mobil 1, Castrol, Royal Purple or any other premium lubrication product?

In addition to being a first-of-its-kind motor oil made from natural gas, Pennzoil Platinum with PurePlus Technology delivers COMPLETE PROTECTION including:

1. Cleaner Pistons: Keeps pistons up to 40% cleaner than the toughest industry standards (Based on ILSAC GF-5, Sequence IIIG piston deposit test using SAE 5W-30, and Ford, Chrysler and GM specifications. Does not apply to Pennzoil Platinum Euro products) Additionally, keep pistons up to 8% cleaner than Mobil 1 and up to 17% cleaner than Valvoline SynPower (Based on pistons from standard V6 engine in ASTM Sequence IIIG piston deposit test using SAE 5W-30. Does not apply to Pennzoil Platinum Euro products)

2. Better Fuel Economy: Drive on average an extra 550 miles per year vs. a dirty engine (Fuel economy measurements made using CAFE cycle under FTP75. Avg of 550 extra miles based on mixed city/highway miles and US avg of 13,476 miles driven per year with 4.1% better MPG vs dirty engine. Source, 2011. Follow OEM recommended oil drain intervals)

3. Horsepower Protection: Helps protect engines from loss of power

4. Unsurpassed Wear Protection: No other leading motor oil provides better protection form friction (Based on Sequence IVA wear test using SAE 5W-30)

5. Excellent Performance in Extreme Temperatures: Provides faster low temperature oil flow and protects in extreme heat.

Could you address operators of GDI-Turbo vehicles regarding the effects of certain additives such as calcium and their impact on LSPI (low speed pre-ignition)? There’s much discussion and concern by operators of these vehicles that Pennzoil’s additive packages are predisposed to LSPI as compared to other brands.

Low speed pre-ignition (LSPI) is more a phenomenon of engine design – and as you mentioned, occurs more frequently in gasoline direct injection (GDI) turbocharged engines. It is really a phenomenon for prototype or experimental engines that are still in the Research & Development phase, and oils with high levels of calcium-based detergents can increase LSPI frequency. HOWEVER, by the time the engine is fully designed and released to the market, it must be compatible with the available motor oils in the marketplace. Thus said, there is no need for concern.

Can you share some aniline points?

The aniline point is the lowest temperature at which an oil product is completely miscible with aniline in a 1:1 volumetric ratio. Unfortunately, we cannot share data points for proprietary reasons.

It’s not clear to me or others whether or not Pennzoil High Mileage Vehicle is a conventional or synthetic blend motor oil. Could you please confirm if it is conventional or synthetic blend?

a. Pennzoil High Mileage is a conventional motor oil that has been enhanced with a unique combination of special conditioning agents and additives to help stop leaks from seals and reduce the oil consumption that is typical of older, worn engines

b. However, Pennzoil Platinum High Mileage (our newest offering) is a full synthetic motor oil formulated with PurePlus Technology. PPHM is currently available in 5W-20 and 5W-30 viscosity grades and is designed to deliver less oil burn off and reduce leaks/oil consumption in older vehicles as compared to other high mileage motor oils.

I am interested in Pennzoil Platinum High Mileage oils. They do not seem to meet many certifications outside of SN at this time. Do you plan on certifying them for ACEA ratings (A1/A5)? Will this oil be assigned a GM Dexos 1 license

Pennzoil Platinum High Mileage is specifically formulated for engines over 75,000 miles. Because this motor oil is designed for high mileage vehicles that have often passed the manufacturer warranty period, it does not carry as many manufacturer specifications. (A few of these specifications require expensive licensing fees.) Rest assured, Pennzoil Platinum High Mileage still provides complete engine protection without compromise – in addition to helping to reduce leaks and oil consumption in older vehicles.

Most oil companies make high mileage 20W50 weights. Does Pennzoil ever plan on making a high mileage 20W50? Or even a synthetic 5/15/20W50?

The automotive industry has been recommending lower viscosity grade motor oils over the past few years, so you will start to see lower viscosity grades offered, as opposed to higher, even in high mileage motor oils. However, Pennzoil does offer Pennzoil High Mileage Vehicle in SAE 10W-40 and Pennzoil GT Performance Racing in SAE 25W-50.

Gumout GDI Q&A June 2015

Gumout question and answers.

Find below a comprehensive Q & A about all things Gumout

1. Is there going to be a product that (not maybe or somewhat) takes care of the intake valve deposit issue that can be used without extensive engine disassembly?


Gumout is researching the solution to direct injection Intake Valve Deposits (IVD). Because fuel is not sprayed directly onto the valves as in a Port Fuel Injection (PFI) engine the delivery of a fuel system detergent to the deposits is more difficult. Our Gumout Multi-System Tune Up can be introduced to the fuel system via vacuum line and will clean valve deposits; however, we are conducting more robust third party scientific testing to determine a statistically proven level of cleaning.

2. Is there a product that takes care of the intake valve deposit problem that won’t void manufacturer warranties or dislodge particles that will damage the turbocharger? As Ford (for one) doesn’t seem to believe there’s any way to clean deposits without turbo damage absent removing the cylinder head, this seems a bit of a challenge. See above


3. Can the new GUMOUT GDI fuel system additive safely be used in non-DI engines?


All Gumout gasoline additives can be used in non-GDI engines, including those recommended for GDI.

4. Is there a Gumout product that will prevent intake valve deposits on GDI engines with regular use? See number 1


5. Are intake valve deposits are from oil?


Studies have shown that direct injection intake valve deposits contain ten times the mineral based components as port fuel injected engines. Analysis shows much of this material is from the oil. Additional work shows that the type of oil used in the crankcase closely correlates with the composition of the deposits, so yes oil is causing a large part of these deposits. The oil and other contaminants enter the intake manifold through the exhaust gas recirculation (EGR) and positive crankcase ventilation (PCV) systems. From the intake manifold the oil mist moves past the valves into the combustion chamber. However, some of it sticks to the valves and to previous deposits building even more deposits. This happens on both PFI and GDI engines.

6. In regards to the delivery of fuel additives to the intake valves of a DI engine; what is Gumout’s opinion of a fine mist introduced via throttle body, at a steady rate while the motor is being idled? Better, worse, or no difference than induced via vacuum, i.e. brake booster?


This area is still under investigation, but early indications are the vacuum line is preferable when available; however, using the vacuum hose from the brake booster is not recommended. The best choice is locating a line that ties in directly behind the throttle body. Using the wrong vacuum source can lead to:
• Overheated catalytic converters
• Possible engine damage
• No cleaning of the intake manifold, and may clean only one intake runner and cylinder

7. What is the proposed mechanism for any cleaner additive to help maintain intake valve cleanliness?


Gumout additives maintain intake valve cleanliness with regular use by removing materials that act as precursors to deposits. This reduces deposit formation. Polyisobutylene Amine (PIBA) works well cleaning port fuel injectors and intake valves. However, Polyetheramine (PEA) is the optimal cleaning technology for the combustion chamber and the parts that a PIBA based product will clean. That’s why PIBA alone cannot clean the complete fuel system. Cleanliness is also maintained when Gumout is used to remove deposits before they can accumulate enough to cause drive-ability issues (the problems caused by the growth of deposits). Gumout products with PIBA or PEA can also remove deposits that have been allowed to develop, but we recommend using our fuel additives as part of your preventive maintenance program so you don’t develop fuel related problems in the first place.

8. If any cleaner survives the combustion process, how is it not an added hydrocarbon that affects the cat converter, and how is this not a violation of the emissions regulations and clean air act?


The cleaner found in our complete fuel system cleaners and multi system tune up is not a pure hydrocarbon. It contains nitrogen based polymer (PEA) that survives long enough to remove deposits and then burns cleanly without causing damage to catalytic converters. Some other materials used in our competitors’ products decompose before they can perform in an engine. Some may actually increase deposits.

The PEA and other materials in Gumout fuel additives are registered with the US EPA in compliance with federal regulations. While US EPA does not endorse or approve formula performance, they will not register formulas containing components that are not tested and previously approved or new materials that may harm catalytic converters.

9. Which Gumout products are specifically recommended for GDI? What characteristics of GDI do the recommended Gumout products help? Which Gumout product is best for GDI systems?


Gumout All-in-One, Regane Complete Fuel System Cleaners and Multi-System Tune-Up are all recommended to clean both the injectors in direct injection engines and the combustion chambers. Performance on intake valves is under investigation, but our multi-system tune up can be introduced to the fuel system via vacuum line. This method has been proven to provide clean valves and ports, but again we have testing in the works to provide a more comprehensive review of the efficacy of the product on GDI valves using this application method. Once those tests are complete we will publish those on our website and share with the BITOG community.

10. Can the Gumout All in One be used to store cars fuel where its in a garage 8 months a year?


All in One complete fuel system cleaner does not contain a fuel stabilizer in its formulation; for the best results, use Multi-System Tune-up continuously in a vehicle that doesn’t get driven regularly to help stabilize fuel. Multi-System Tune-Up will prevent gum and varnish formation during storage and provide additional cleaning. Use this product every 3,000-5,000 miles for regular cleaning and conditioning; but you can also use All-in-One Complete Fuel System cleaner every 3,000 miles for a more heavy duty cleaning due to a higher level of PEA in the formula. In addition All-in-One reduces friction for better fuel economy. This routine also works well for marine and any seasonal 2-or 4-cycle equipment. (It does not replace the oil added to 2-cycle fuel.)

11. Does Gumout have any plans for a relatively easy and not too expensive DIY one(or two) man process to clean or regularly maintain GDI intake valves. I’ve seen the aerosol spray can made by a competitor but that seems an unwieldy and uneven dispensing process to me. Another competitor has an straw-like attachment to the throttle body from the aerosol can that keeps the throttle body intake system intact/attached while the product is evenly dispensed over time. Not sure of that product’s effectiveness but a product/process like that would be preferable imo. I’d be interested in a readily available product similar to the latter.


Cleaning intake valves in gasoline direct injection engines is an active area of research and we are seeking to optimize our formulas and the cleaning process. See answer to question one for more details.

Chevron Q & A

Chevron question and answers.

Find below a comprehensive Q & A about all things Chevron

Does Chevron make the PAO base stocks for Royal Purple?


Chevron does not make PAOs but Chevron Phillips would. However, Chevron Phillips does not disclose who they sell their bases to, and thus, we wouldn’t know for sure either.

Do you have any plans of releasing your full synthetic 5W-40 in single quarts? (HAVOLINE)

a. Non-Euro 5W-40 is available in quarts, but only sold at participating installers, please check the site finder for local installers that carry Havoline.
b. Note: There are no retailers that are taking the Euro 5W-40 at this time; therefore, and although not product specific, Havoline ProDS Full Synthetic Euro SAE 5W-40 may be available for a motor oil service at select participating professional installers located on the site finder.

Havoline PRO DS Full Synthetic available in 5qt containers?

The 5 quart package of Havoline Conventional and Havoline High Mileage can be found on shelves of major national retailers – always best to check their websites first for your local store.  Havoline ProDS Full Synthetic in the 5 quart pack will start showing up at retail by the end of the third quarter.

Will it ever be sold at Walmart? Like the conventional. (Havoline)


Havoline Conventional and Havoline High Mileage Motor Oil is stocked at Wal-mart stores. Please check for participating sites.

Will we make a 5qt container of Synthetic ProDS available at Walmart?


We are in ongoing discussions with all major national retailers about stocking the Havoline product line. Also, input and demand pull from consumers definitely aids the retailers’ decision on which products and packages to stock.

Is Havoline available in 0W-20?


Havoline ProDS Full Synthetic SAE 0W-20 is available for an oil change service at many professional installers across the U.S. Please go to the site finder to locate participating installers.

When do you plan on introducing your products into wider distribution? Many of us grow bored with wide availability of only of SOPUS, XOM, Ashland and BP’s Castrol brand. A little variety is always a good thing, and you could have the members here arguing about how your oil is better than (insert brand name here).

Gumout Q & A – April 2015

Gumout question and answers.

Find below a comprehensive Q & A about all things Gumout

1. Interested in GDI fuel system maintenance, from tank to high pressure pump to injectors and upper cylinder. Is there a product with DI in mind?


Our Complete Fuel System Cleaners (CFSCs), Regane, High Mileage Regane, All in One and Multi-system Tune-up all have Polyetheramine (PEA), which is the only known cleaning agent that can survive the harsh temperatures found in the combustion chamber. It can remove hard to remove carbon deposits that rob your engine of performance. So not only can it clean the piston tops, cylinder heads and cylinder walls, but it can also clean up deposits found on GDI injectors and keep them clean for up to 3,000 miles. The chemistry also cleans up deposits from fuel tank, pumps (including high pressure) and fuel lines.

2. I almost always use Gumout All in One but occasionally use the octane booster. Does the octane booster have PEA in it? The side of the bottle lists its dangers and lists Amines. I run both of your products in a 2012 Hyundai GDI with 0 ethanol fuel and pennzoil synthetics. Mileage is 118,112 and I still get 38mpg+


No, our Octane Booster doesn’t have PEA in it. In fact, it has only a small amount of injector detergent. Our Octane Booster’s main benefit is to boost octane rating and help stop knocking and pinging and restore lost performance

3. How does your product keep GDI (direct injection) intake systems clean when fuel doesn’t reach Intake Valves in a conventional PFI way?


Our Complete Fuel System Cleaners and Multi-System Tune-Up will clean direct injectors by using PEA simply by pouring the product into the gas tank. However, since the injector in a GDI system is no longer in the port, buildup can occur on intake valves and is a lot tougher to remove. To clean the valves and ports in a GDI system, we recommend using our Multi-System Tune-Up by introducing the product using the induction method. This requires the product to be slowly introduced to the intake system via a vacuum line. This provides a concentrated dose of product that will help remove valve and port deposits in GDI systems

4. How much PEA does your “All in ONE” product have? I understand you can’t give exact percentages. How about a small range then? “Like ALL IN ONE has between 50% and 60% PEA.”


Please understand that the percentages of PEA in our products are proprietary, but all of our Complete Fuel System Cleaners have the correct amount to clean up deposits in just one fill up. What differentiates them are the other conditioning additives in the formulations and the amount of gallons that can be treated.

5. Can Gumout provide more before and after photos/videos of their product in action? Words are great but pictures (especially videos) are even better.


Please visit and for relevant videos and pictures. However, keep in mind that Complete Fuel System Cleaners take time to remove deposits. They typically remove deposits by the time you have gone through a tank of gasoline. So, depending on your driving habits, this could be a week or even a month, so it’s virtually impossible for a video to show this cleaning action over this time frame. Before and after images and videos are the standard for showing the benefits of using the product. We continue to test our products and will provide more photos and results as we get them. You can visit and visit our Science pages for updates.

6. Can any product (including Gumout) “fix” old gasoline? At least one product claims it can. Or does “old” gas need to be tossed?


While we don’t know of any product that reliably restores degraded fuel, we do have chemistry that keeps fuel fresh in storage. We recommend about 1 ounce/gallon Gumout Multi-System Tune-Up to treat fuel for any seasonal or marine engine whenever it may need to be stored or when it may need the fuel system cleaned up. This works well in 2-cycle engines also but does not replace the oil mixed with the fuel.

7. Does Gumout all in One really cleans piston crown carbon deposits? How much percent for each treatment?


We have independent test results that consistently show All-in-One really does clean piston deposits. The percentage cleaned varies from vehicle to vehicle and even from piston to piston in the same engine. It depends on the engine, the fuel and the driving cycle, so we cannot give a percentage for a specific engine.

8. Are you aware of ChrisFix video on youtube about it?


You would need to be more specific about what “it” is you are referring to for us to comment.

9. How many octane points does your octane booster raise a tank of gasoline?


An octane point is a tenth of an octane number, so a ten-point increase raises the fuel octane about one octane number. When used as directed, Gumout Octane Booster typically raises fuel octane about ten points. The exact number depends on the octane response of the specific fuel used and the exact number of gallons treated. Also, using more product will increase octane but less than expected. If one bottle increases octane 10 points, two bottles will not increase 20 points

10. Do you have before and after images from a borescope?


Most of our data is quantified by weighing deposits or measuring their thickness. This is much more accurate. There are specific examples where boroscope pictures show improvement, but to the untrained eye, the pictures are not convincing and may be misleading.

11. Do your amines survive combustion and if so, are they effective in cleaning the EGR valve?


Our products that have PEA can survive the combustion chamber environment. It will clean the EGR valve if the formulations with PEA are introduced through the induction method that involves applying the product via the correct vacuum line. See the answer to question 21 for more details.

12. What is the mechanism by which additives keep a direct injection system clean? If they combust fully, how do they support cleaning of valves and other locations where DI engines are known to foul? If they survive combustion, how do they not cause excess HC emissions numbers and failure by the EPA?


Please review the previous answers for your first two questions. The PEA formula we use cleans injectors and intake valves as it flows past them before going to the combustion chamber where it survives long enough to clean those deposits. It is burned but burns cleanly unlike many old style oil based additives. These produce more char, leading to deposits of partially burned material. PEA is designed to burn cleanly without leaving ash or carbon behind. Emission reduction is the result of the cleaner engine performing better. During the cleaning process, emissions may not be immediately reduced. Emission testing should be run after the deposits are removed, not during deposit removal. The valve deposits in direct injection gasoline engines may not be removed by a fuel system cleaner added to fuel. To clean those deposits, we recommend the induction method where product is introduced through the vacuum intake. Severe deposits may require disassembly and mechanical cleaning.

13. Some of your additives containing PEA can be used in the oil as well as the gas. What purpose does PEA serve in the oil?


Assuming it cleans sludge and varnish in the crankcase, PEA is not specifically designed for use in the crankcase but still retains its detergent properties. There are other additives in the Gumout Multi-System formula that loosen sludge and varnish, particularly if used just before an oil change. Longer term anti-oxidants stabilize the oil reducing the oxidation that results in sludge build-up.

14. I have a vehicle known for oil consumption due to coking at the piston rings.Some people have had success using various cleaners or solvents to perform a “piston soak” on the vehicle. Is Gum Out “Expert” Multi System tune up appropriate for use in a piston soak? Will it provide any ring cleansing if used in the crankcase?


Gumout Expert Multi-System Tune-Up will provide a solvent soak, although the concentration recommended is at level that will not to provide this benefit. That is because the high concentration needed for a solvent soak will dilute the oil beyond the safe limits of engine operation. That is why we do not recommend this approach.

15. Will Gumout Multi System cleaner help with regards to cleaning engine varnish if added to motor oil?


Yes, and an additional effect is to prevent future varnish build up because the formula contains antioxidants that help prevent oil degradation.

16. CRC says % of PEA in their product, and considering they are your competitor, I feel like you also should specify the same info.


CRC has a very large portfolio of products. You will need to be more specific in order for us to answer your question.

17. I have used gumout carb spray and throttle body cleaner for as long as i can remember and always had good results. Although I had a number of cans that had spray issues over the years. I used to also use the gumout in the gas but i have switched to Techron not for any special reason.


If there isn’t any special reason, we’d love to have you return to Gumout. Hopefully the information provided on this forum and our website will provide you with enough information to make an educated decision on which product is right for you. The key thing is that you are doing the right thing by wanting to maintain your vehicle.

18. Is there a concern over using gumout products with PEA during the middle of oil change interval?


There is no concern. All our PEA products may be used at anytime during, before or after an oil change. They have been tested and show no ill effects to the motor oil.

19. Can gumout improve winter startup and do you have pictures and or videos to show the improvements using gumout with PEA?


Gumout Regane, All-in-One and Multi-System Tune-Up all clean the complete fuel system to make the vehicle easier to start and run more smoothly whatever the weather, but this is particularly important in the winter. The motor oil is also a major factor in Winter startup. Use the manufacturer-recommended oil viscosity for the winter and avoid heavier weight oil or oil thickening additives to let the engine easily turn over at start-up.

20. Will gumout with PEA clean egr,pcv, and other emissions sufficiently over time or over just one application bi monthly?


Gumout with PEA provides one tank clean-up, so benefits will start after just one tank. Bi-monthly application, or every three thousand miles, will reduce deposit buildup before problems develop and keep the engine running at peak efficiency. EGR and PCV are not directly fed by the fuel system. They vent the crankcase through the intake manifold and past the ports and valves. To clean these items, an induction procedure is done either as a fuel system service done by a professional or through the DIY method mentioned in the answer to the question below; however, Regane or All-in-One will clean ports and intake valves in a port fuel injected vehicle.

21. I use CRC intake valve cleaner for GDI, can your all in one or multi purpose bottle that resembles the stp and seafoam be used to directly to clean the throttle body and manifold if applied through spray mister and squirt bottle?


Yes, our Multi-System Tune-Up can clean valves and port in GDI engines as long as it is introduced to a vacuum line that leads to the intake system – never use the vacuum line that comes from the brake booster. It’s important that the product is introduced at slow rate to avoid vapor lock that can cause damage to the vehicle. When used correctly, our Multi-System Tune Up will provide maximum cleaning power to help remove the performance robbing build up in GDI systems – by pouring half in the tank and half via induction, it provides a powerful 1-2 punch.

22. Do Gumout products provide lubrication to the fuel system?


Our Regane High Mileage Fuel System Cleaner, All in One Complete Fuel System Cleaner and Multi-System Tune-Up all have friction modifiers to provide lubrication to the fuel system. All-in-One has a high level of friction modifier, while Regane High Mileage has a lower amount. Gumout Multi-System Tune-Up has different chemistry, so we cannot compare performance directly, but it also demonstrates friction reduction compared to untreated gasoline.

23. Do you products work well in small engines?


Yes, the ratio of product used would be different but will provide the same benefits. Please read the directions on the products to know what amount of product is the optimal amount for your small engine.

24. Gumout Professional Pro 2 Step cleaner is being sold at Ollie’s Bargain Outlet. The intake portion needs an applicator which is unavailable. Can the intake bottle be used in the gas tank. Will it benefit the vehicle to use it this way. Does the gas tank portion have any PEA in it?


This product was not intended to be sold to the general public due to the skill level and equipment needed to properly and safely use the product. Another concern is when product is sold to bargain outlets, not through our sales channels such as in this case, because the product age may be beyond the shelf life that we recommend. Typically we do not recommend using any of our products if they are older than 4 years old. Please call our hotline and provide the coding on the packaging, and they can determine the age of the product. If the product is still within the approved date range, the liquid intake cleaner can be used in the gas tank and it does have PEA in the formulation.

25. Why should I use gumout over other brands such as lucas, seafoam, royal purple etc?


There are many products and brands that claim to do a lot and some of them can back up their claims and others can’t. We at Gumout are being as transparent as we can about the ingredients we use and the certified tests conducted to prove that our products work. We recommend you search for similar information on these other products from the company’s websites and official documents. If they don’t provide this information, ask for it. If they aren’t using ASTM industry recognized testing methods, be concerned. If they won’t provide you with this certified test results, then our recommendation is to go with the brands that are willing to give you the information you need to make the right maintenance choice.

26. How well does Gumout work with ethanol in gas?


All Gumout products have been extensively tested with E10, the 10% ethanol fuel required for most areas of US. Performance is effective in this fuel and E10 was used for much of our testing program to support performance claims. If ethanol is a concern, particularly with marine engines, we specifically recommend treating the fuel with Gumout Multi-System Tune-Up to prevent damaging effects of oxidation and corrosion and to keep the fuel fresh during storage.

27. I am confused by how your fuel treatments are marketed. Regane Complete, Regane High Mileage, and All-In-One Complete seem to serve the same purpose. I never really know which one to choose since the only thing discerning them are their names and sizes. Why not simplify it to one formula? Do I get more detergents by buying the All-In-One/Regane High Mileage over Regane Complete? Is it possible to use too much or too often?


All 3 have PEA as the cleaning agent, High Mileage Regane has an additional friction modifier to lubricate upper cylinders, which is especially helpful for older vehicles that may have more wear and tear than newer vehicles. All in One has more PEA and friction modifier and treats more gallons than the other 2 products, so it provides the most benefits of the three items. We provide consumers with multiple product choices based on what their engines need, how many gallons they want to treat and the value they place for each product. Regarding how much to use, we recommend using one entire bottle before you fill up. Each of these three products will last up to 3,000 miles.

28. How is Gumout better than similar competitive products?


See answer to question 25 and visit our website and

29. Could you compare and contrast the product lineup differences between Canada and the United States for us? Up here, we customarily see Gumout REGANE Complete Fuel System Cleaner and the High Mileage version, and I’m under the assumption that these are two of your top products.


You are correct. These are two of our top products. Both are complete fuel system cleaners that clean port fuel injectors, intake valves, combustion chambers and direct injectors. In addition, High Mileage Regane also lubricates the piston ring/cylinder wall area to reduce internal engine friction, providing better fuel economy.

30. What gains can a consumer who purchases only Top Tier certified fuel expect by using a fuel system cleaning/lubing product at a regular interval, versus only using Top Tier certified fuel? As a follow up, if a consumer uses non Top Tier fuel, would you say that regularly using a fuel system additive would leave the fuel system in the same state as a consumer who only used Top Tier fuel without using additional additives?


Top Tier Fuel is recommended because it does a superior job of preventing engine deposits overall. However, it does not completely eliminate all deposits. Recent studies have shown that, even with top tier additive chemistry, fuel from some sources continues to build deposits, so an additional fuel system treatment will show benefits. If non-Top Tier fuel is run in the vehicle, then complete fuel system cleaners are usually needed to clean up the engine. The best results come from regular use to keep deposits at a low level before they reduce performance. This is not exactly the same as using Top Tier fuel consistently. Overall, the combination of Top Tier Fuel with the occasional Fuel System Treatment is ideal.

31. I would appreciate any before and after pictures you may have of cylinder combustion chambers/top ends. Especially showing change after a single treatment or multiple treatments with Gumout products. Before and after pics of various top ends using Top Tier Fuel(with descriptions of mileage and drivng type, severe stop and go vs extended highway miles) vs Top Tier+Gumout would be impressive and if convincing….would be the BEST marketing strategy you could possibly provide


In our laboratories, we use numerical data to quantify our results and determine how much improvement results from using Gumout additives. To us, the numbers are more important and clearly indicate the level of performance. However, pictures are excellent at communicating results, so we are investigating the addition of additional pictures.

32. PEA concentrations per bottle?


While we cannot discuss specific formula details, we can let you know that when you buy a bottle of Gumout Regane, Gumout Regane High Mileage or Gumout All-in-One Complete Fuel System Cleaners most of what is in the bottle is the additive package we use to deliver performance. One of the critical components is PEA, but other molecules are also used to make the formula even better than PEA alone. Each contains some added solvent to assure proper delivery and dilution, but Regane has more than 70% additive, Regane High Mileage has over 75% and All-in-One has about 80% by volume in the bottle.

33. Is there a difference between the “high mileage” and the “Complete” products both with Regane?


Our High mileage version of Regane has a dose of friction modifier added to lubricate upper cylinders. Both products have the same level of PEA cleaning agent.

34. The optimum method for application says it treats 50-70 litres of fuel. That is pablum for the general public. I really want to know if I add a full bottle to eg: 20L of fuel am I going to get the results I am looking for in cleaning my fuel pump, injectors etc vs 40L or more.


Add a full bottle to a full tank of fuel in any passenger car. 50-70 liters is a recommended treat rate and the minimal dilution level used to test performance claims on the label. A smaller tank will have a higher concentration, so cleaning will be faster but may occur over a shorter period of time depending on tank capacity and fuel economy. You will get the results you want. However, use when filling the tank, since the product is not a fuel and the engine needs the petrol (gasoline) to burn properly when running the vehicle.

35. I was looking at the Gumout website and it seems like there are a lot of products that say they will clean the combustion chamber but I’m wondering which one of those products does the best job of this particular task? That’s my biggest concern when using a fuel system treatment personally.


Our Complete Fuel System Cleaners and Multi-System Tune-Up all clean the combustion chamber effectively; however, the difference between the products are the addition of other additives that help condition the engine. All will have a high cleaning level. As an additive to pour into the tank, Gumout All-in-One treats the most fuel (35 gallons) and provides the most PEA, so it will have the highest treatment level if used in a smaller tank. Multi-System Tune-Up offers the most choices where to use and is an excellent fuel stabilizer, so it is the best choice for a broad range of applications.

36. I have been happy with the Gumout All-In-One cleaner I had been using, and felt even better about it after reading the Q&A regarding the PEA content. I have been looking for one simple, short, easy answer. Which product is the best/most effective to use as an in the tank fuel system cleaner? All-In One or Multi-System Tune Up?


Our Multi-System Tune-Up product has a few more benefits than All-in-One such as: it can stabilize fuel and oil, it can be used in diesel engines and can also be used in the crankcase. If you don’t need these additional benefits, then All-in-One is still the right choice, but if your vehicle can benefit from these additional benefits, then head down to your favorite store and pick up a bottle of Multi-System Tune-up.

37. Are the Expert Series the same as the above mentioned products, only marketed for Autozone? Or do they differ?


The Fuel system treatment is new to the Gumout family. It is the same formula as our fuel injector cleaner, but we’ve added an upper cylinder lubricant to provide wear and tear protection between the piston and cylinder wall. Expert Series Regane and All-in-One offer the same cleaning and conditioning benefits of their non-Expert Series counterparts. Also, within the Expert Series line, are two kits: Horsepower and Performance restoration. These are unique to the Expert Series line and offer specialized products to help get you the most out of every mile.

Gumout Q & A – June 2014

Gumout question and answers.

Find below a comprehensive Q & A about all things Gumout

It is my understanding that the products listed as “Fuel System Cleaners” contain the ingredient PEA, but do the lower tier cleaners such as the “Fuel Injector Cleaners” and “Fuel Additives” also contain some PEA?

Also did the formulation become less potent with the “All in one” cleaner sometime between 2010-2012. I saw an older stock bottle and it looked much darker and smelled more potent.

Gumout All in One Comparison

Is there any reason to choose the lower tier products such as “regane or regane high mileage” over the “all in one” other than cost?



Fuel additives without PEA often contain a different ingredient called PIBA that clean carburetors and indirect port injectors. At high concentrations it can clean intake valves, but it does not clean combustion chambers. You need PEA to clean all three areas, fuel injectors, intake valves and combustion chambers.

All-in-One color variations were due to variation in some raw materials used in certain batches. The color change did not affect product performance, but we adjusted our production specifications to use only materials of the same consistent color so that the product color does not change. However, there still may be some older product on the shelf that is darker than others – feel confident in using the product regardless of the color difference because the potency is the same.

Gumout All-in-One can be used in any gasoline engine at the recommended treat rate, or even somewhat more concentrated. Regane and Regane High Mileage are designed to treat smaller fuel tank sizes – 21 gallons vs. 35 for All in One. However, High Mileage Regane has a friction modifier to help restore lost MPG and reduce upper cylinder wear. All in one has a larger dose of this friction modifier as well as more PEA. All three products can be used at up to double the recommended treat rate for even stronger cleaning.

I am a Techron user, how does Gum Out All in One compare? Does it contain PEA in equal or higher concentration in comparison to Techron?



Chevron doesn’t share their formulation information but independent testing that we conducted does confirm presence of PEA in their fuel system cleaners (FSCs). The PEA levels in our formulations are proprietary information as well, but a good way to compare is to look at how many gallons each product treats. All in One 10 oz bottle treats 35 gallons which is supported by industry recognized ASTM testing; Techron FSC 20 oz treats 20 gallons, their 16 oz treats 16 gallons.

Chevron doesn’t publically state how they determine their treat rates, but one would assume they have conducted legitimate testing.
In addition All-in-One has a friction modifier to reduce internal engine friction for better fuel economy. This is an advantage that Techron does not have.

Direct injection is reality. We have heard that some cleaning agents can “survive” the combustion process and clean through PCV or other means. This doesn’t necessarily make sense given HC regulations and the effect it would have on catalytic converters, however given the parallel reality of deposits in DI engines, cleanliness and additives to support engine cleanliness are essential. Can you describe the chemistry, mechanism, and tests/validation used to develop DI-suitable additives? Which of your products is most suited for maintaining valve, intake and injector cleanliness in direct injection gasoline engines, and why? (JHZR2)


We recommend PEA to clean direct fuel injectors. In a GDI (gasoline direct injection) engine the injector tip is in the high-pressure high-temperature environment of the combustion chamber. Carburetor and indirect port injector detergents are generally not made to survive the combustion process adequately to clean in this environment. However, PEA will. Since the tip of the injector is in the same environment as the rest of the combustion chamber the deposit characteristics are similar. They tend to be harder and more carbonaceous than the softer (and easier to clean) varnish and deposits found in cooler areas of the engine.

These deposits reduce fuel economy, reduce power, cause rough idling, cause hesitation and/or surging and cause hard starts. They interfere with air and fuel flow within the engine. Combustion chamber deposits cause knock and ping or even carbon rap that may cause severe engine damage. Modern computers may compensate for these deposits to some extent, but the trade-off is a lack of power and performance.

PEA is a polymeric molecule that contains portions that are more polar (the heads) that attach to the deposit particles along with a fuel soluble hydrocarbon tail. The molecule can then pull the deposit particle from the surface into the bulk fuel droplet where it is further combusted and/or blown out with the exhaust.

PEA is good at cleaning intake valve deposits (IVD) in port fuel injected engines because the treated fuel is sprayed directly onto the intake valve. However, direct injectors spray directly into the combustion chamber missing the valves. In some engines there is enough misting onto the valves when they are open to provide some cleaning, but in many engines the spray never reaches the IVD. In general we recommend an induction cleaning to take care of these deposits. Induction cleaning can also remove deposits formed in the intake manifold area that result from the crankcase ventilation system or other fugitive emissions.

Product performance is supported through a series of industry recognized ASTM laboratory bench and engine tests such as D6201 Engine Test, D665B Rust Prevention Test, D525 fuel stability test, just to name a few.

Engines are run and disassembled and the deposits are actually measured before and after clean-up using the PEA detergent. The appearance is viewed and rated and deposits are weighed in some areas of the engine or thickness is measure in other areas. Engine test stands, chassis dynamometers and vehicle fleets are all used to evaluate performance.

There is a substantial amount of testing and validation behind all Gumout Products. For more information about our fuel additive line of products visit

The ‘All in One’ 10 oz bottle claims to be good for “up to 35 gallon gas tanks”.
If I used half a bottle in each of my cars (14 and 15 gallon gas tanks) would it be fully effective?

What is the PPM of PEA in this product?…in regular Regane?…. in High Mileage Regane?

Would it be more effective to add Regane before a long highway trip where the entire tank of gas is used or when the car will be used for several shorter trips where the PEA gets to ‘soak’ into the valves etc…?



Splitting a bottle of All-in-One as you suggest will be effective since you are close to the recommended treat rate. You can also use the entire bottle for increased efficacy.
The exact formula is a proprietary trade secret, please see our answer found above in the previous question. All three products do have PEA at a level that can clean the complete fuel system in one tank of gasoline.

Regane will show benefits whether it is added before a long trip (30+ miles at 60 MPH) or for shorter local trips. However, longer times are better because the vehicle runs at full operating temperature where the detergents are most effective.. On very short trips, the engine is not hot enough to support optimal combustion and allow the product to work its best. Overall we would favor a long highway trip at freeway speeds

Do any of your fuel additives contain anything to clean sulfur deposits from gas gauge sensors?



The damage to gas gauge sensors was the result of sulfur compounds causing silver corrosion. Silver corrosion was damaging fuel sending units and became a problem due to local refinery issues several years ago. The refinery issue was resolved and silver corrosion is not known to be an ongoing problem any longer. Unfortunately, once the corrosion has occurred, the only option is to replace the unit.

Gumout additives contain inhibitors that prevent corrosion on critical engine parts. However silver requires a separate inhibitor that is not part of our formulations since the refinery issue has been resolved and therefore not needed in our fuel additives.

I too would like to know which method of engine running would be more effective at cleaning everything. Steady highway rpm or city type driving.
It’s been debated here more than once and I can see benefits to both methods but I’m guessing the city type driving would be more beneficial because of the varying cylinder pressures and volume of airflow changing rather than just a steady rpm, unless those rpm are high enough that it creates velocity.

And please not some bull form answer that both will clean effectively blah blah blah.



See previous answer to this question above.

Could you just list the concentrations of PEA in your products?



See detailed answer in previous question. We don’t share this info as it is proprietary just as Chevron doesn’t share their formulation details.

Does gumout use anything that would be considered better than PEA in their products for cleaning?



We continually investigate detergent chemistry to ensure we are using the most up to date and effective additives. Currently PEA is the safest and most effective technology available for cleaning the entire fuel system.

Please list the amount PEA contained in the entire bottle rather than percentage. The concentration alone is not the correct way to measure what gets eventually added to my tank. When I dump a bottle of your FSC or a competitor’s all I want to know what is the final PEA amount in my tank and it does not matter if you had double the concentration but half the bottle size.

Tell us how much gm/ml/oz of PEA each of your bottle has.



See previous answer to this question. We don’t share this info as it is proprietary just as Chevron doesn’t share their formulation details.

Your top 3 fuel system cleaners, (Regane, Regane high mileage, and All on one).

Do these 3 products contain the same percentage of PEA?

Why isn’t the All in one product available in Canada?



All three of these products contain the proper amount of PEA to clean a full tank of fuel as listed on the package label. The larger bottle of All-in-One does contain more PEA than Regane of High Mileage Regane; see previous answer for more details or visit for further information.

Retailers in Canada may have chosen not to stock All-in-One. It is available through or other internet retailers.

8. Is there any plan to market Pennzoil Platinum® or Pennzoil Ultra Platinum™ Full Synthetic motor oils with PurePlus™ Technology as a high mileage oil drain interval oil?

Pennzoil Platinum® Full Synthetic motor oils with PurePlus™ Technology are extremely robust formulations, but lubricant marketers do not set oil drain interval recommendations. Drain interval recommendations are made by engine manufacturers. A potential advantage of using a high quality synthetic is to take better care of your engine and reduce deposit formation, which over time may reduce power, performance, and fuel economy, rather than extending the drain interval.

9. Are there any products suitable for extended drain in excess of manufacturer recommendation once outside of warranty e.g. 15,000 mile performance guaranteed like one of your competitors?

Pennzoil Platinum® Full Synthetic motor oils with PurePlus™ Technology are extremely robust formulations, but lubricant marketers do not set oil drain interval recommendations – these recommendations are made by engine manufacturers. So, if your engine manufacturer recommends 15,000 mile ODI, then we stand behind the 15,000 mile ODI. A potential advantage of using a high quality synthetic is to take better care of your engine and reduce deposit formation, which over time may reduce power, performance, and fuel economy –rather than extending the drain interval.

Licenses / Approvals

GTL / Testing

1. When did Pennzoil begin using GTL base oil in Pennzoil Platinum®?

We began switching production facilities to use PurePlus™ base oil in our Pennzoil Platinum® line of motor oils—bulk, packaged and Eco-box—in 2013. Beginning February 1, 2014, Pennzoil Platinum® packaging indicated the use of this technology was 100%, and all production locations have switched.

2. When did Pennzoil 5W-40 Ultra Euro begin being manufactured with PurePlus™ Technology?

We began switching production facilities to use PurePlus™ Technology in our Pennzoil Platinum® motor oils—bulk, packaged and Eco-box—in 2013. Beginning February 1, 2014, Pennzoil Platinum packaging indicated the use of this technology was 100%, and all production locations have switched.

3. How is PurePlus™ Technology classified? Is PurePlus base oil considered to be Group III+, or Group IV, or some other group altogether?

PurePlus™ base oil is classified as an API Group III product. It is important to note there is no such category as an API Group III+ base oil, interested readers can download and check out a copy of API 1509 for the current official base oil definitions. PurePlus™ base oil is classified as API Group III base oil based on its molecular structure, but it exceeds the minimum requirements for API Group III base oil.

4. What characteristics of motor oils are important when considering them for use in modern direct injection turbocharged gasoline engines, and how do the Pennzoil Platinum® Full Synthetic motor oils made with GTL base oils meet them?

To achieve fuel economy requirements and improve vehicle performance vehicle manufacturers have moved toward smaller turbocharged engines with direct injection. These smaller engines are worked harder to achieve a higher rated output, increasing both the pressure and the temperature in the combustion chambers. These engines provide a demanding environment for the motor oil. Pennzoil Platinum® Full Synthetic motor oils with PurePlus™ Technology keep critical engine parts clean and protected, and they have high resistance to oil degradation and low volatility which helps them to maintain the protection over the oil drain interval also resulting in less need for oil top-up.

5. How does the GTL base oil compare with PAO base oil in the various measures of performance?

While PurePlus™ base oil and PAO base oil differ in regard to viscosity, volatility and chemical composition; PurePlus base oil and PAO base oil are similar in their ability to enable top-of-the-line engine oils to perform at a very high level. The key difference between Pennzoil Platinum® with PurePlus™ Technology and competitive PAO formulations rests with the additive chemistry that is paired with the PurePlus™ base oil. The synergy of PurePlus™ base oil and our best additive chemistry, in the Pennzoil line up of products, results in a fully synthetic motor.

6. Are there different grades of GTL base stocks?

Yes there are different grades of GTL base stocks. GTL base stocks come in 3 grades, denoted 3, 4 and 8. The 3, 4 and 8 base oil grades are produced at the Pearl plant in Qatar.

7. What type(s) of testing have you done with regard specifically to your products’ interaction with and ability to combat intake valve deposit formations in modern direct injection technology series of engines?

Pennzoil Platinum® and Pennzoil Ultra Platinum™ Full Synthetic motor oils with PurePlus™ Technology have undergone many stringent lab tests, industry tests, and OEM tests in addition to millions of miles of field trials. The Complete Protection benefits of the line of Pennzoil Platinum® with PurePlus™ Technology products make them an excellent choice for advanced engines, especially direct injection engines, because the motor oils help prevent deposits and perform extremely well at high temperatures. No other leading motor oil helps keep engines cleaner than Pennzoil Platinum® with PurePlus™ Technology. (Based on pistons from standard V6 engine in ASTM Sequence IIIG piston deposit test using SAE 5W-30. Does not apply to Pennzoil Platinum® Euro and Pennzoil Ultra Platinum™ 0W-40. Pennzoil Ultra Platinum™ keeps pistons up to 25% cleaner than Mobil 1; and up to 35% cleaner than Valvoline® SynPower®. Pennzoil Platinum® keeps pistons up to 8% cleaner than Mobil 1; and up to 17% cleaner than Valvoline® SynPower®)

8. It is widely known that the use of GTL base oil can result in lubricant formulations with exceptionally low NOACK volatility. What are the benefits of low NOACK volatility with respect to motor oil??

Lower volatility means less oil consumption inside your engine. Low volatility is also a key factor in enabling an oil to stay fresher for longer throughout the oil drain. Oil loss through volatilization of light ends can cause contaminants, for example from blow-by gases, to concentrate in the oil. These contaminants can accelerate oil ageing and additive depletion. Low volatility helps to maintain viscosity control and is also helpful from protecting the oil from degradation caused by the very high temperatures that can be encountered in turbocharger bearings. Such degradation can cause the build-up of significant deposits in turbochargers.

9. If Pennzoil Platinum® and Pennzoil Ultra Platinum™ Full Synthetic motor oils with PurePlus™ Technology both use GTL, why does Pennzoil Ultra Platinum™ have such lower NOACK values?

Both Pennzoil Platinum® and Pennzoil Ultra Platinum™ Full Synthetic motor oils with PurePlus™ Technology far exceed the industry requirements for NOACK. In order to address your NOACK values question, we would need more information from your testing. The use of PurePlus™ base oil enables Pennzoil Platinum® with PurePlus Technology with NOACK volatilties of 10% or lower.

10. Will Pennzoil® conventional motor oils be getting GTL base stocks as well?

At the moment PurePlus™ base oil will primarily be used in our Pennzoil Platinum® line of products. However, in the future other engine oils in our portfolio may contain a percentage of PurePlus™ base oil, if required for a specific formulation. Products in the remainder of the Pennzoil portfolio are continuing to use conventional base oils as their primary base oil.


1. Is Pennzoil Ultra Platinum™ Full Synthetic motor oil with PurePlus™ Technology available for purchase in Canada?

Yes, Pennzoil Platinum® and Pennzoil Ultra Platinum™ Full Synthetic motor oils with PurePlus™ Technology are available in Canada.

2. Because not all locations are equal when it comes to Walmart, will you have any way of ensuring that all Walmart locations will stock the Pennzoil Platinum® line of motor oils?

We have made all grades of Pennzoil Platinum® and Pennzoil Ultra Platinum™ Full Synthetic motor oils with PurePlus™ Technology available to all the retailers including Walmart. Please check with your local stores for availability.

Other Shell Products

1. Have GTL basestocks been blended into SOPUS products across the line?

PurePlus™ base oil is primarily used in our Pennzoil Platinum® line of products. However, in the future other engine oils in our portfolio may contain a percentage of PurePlus™ base oil, if required for a specific formulation. Products in the remainder of the Pennzoil portfolio will broadly continue to use conventional base oils as their primary base oil.

2. Is PurePlus™ base oil also used in Pennzoil Gold™ Synthetic Blend motor oil and Pennzoil® Conventional motor oil? If so, at what percentages (regarding ratio of conventional to synthetic)?

Pennzoil Platinum®, Pennzoil Ultra Platinum™, Pennzoil Platinum® Racing and Pennzoil Platinum® Euro Full Synthetic are the only motor oils blended exclusively with PurePlus™ Base Oil at this time. Other products in our PCMO and HDEO portfolios are produced using some PurePlus™ base oil. In the future, we may elect to blend other premium products exclusively with these base oils, and would announce such changes at the appropriate time.

3. Will the PurePlus versions keep my pistons cleaner compared to Pennzoil Yellow Bottle?

Yes. No other leading motor oil keeps pistons cleaner than Pennzoil Platinum® with PurePlus™ Technology. (Based on pistons from standard V6 engine in ASTM Sequence IIIG piston deposit test using SAE 5W-30.)

4. Is Pennzoil considering releasing a lineup of fully synthetic high mileage oils?

Pennzoil will continue to expand the Pennzoil Platinum® with PurePlus™ Technology line of premium products, and we do believe there are unique benefits that PurePlus™ base oil would provide to high mileage motor oil.

5. Should users with higher mileage (or just older) vehicles have a shorter OCI the first time using Pennzoil Platinum® with PurePlus™ Technology, due to its better cleaning capabilities (considering possible release of built up sludge that may not have been cleansed with previous oils)?

Typically, this is not necessary. However, this response is based on how clean the engine is. If the engine is dirty, we do recommend shortening the OCI to drain out the build up that was in the engine.

6. Does Pennzoil have any plans to produce a product for flat tappet high valve spring load application? i.e., Muscle Cars / Hot Rods…

There are not currently any plans to make a Pennzoil product for this application.

7. Have you considered making a high VI oil? If so or not do you think this is an important parameter to design an oil and why?

This is difficult to answer without context. By conventional standards Pennzoil Platinum® and Pennzoil Ultra Platinum™ Full Synthetic motor oils with PurePlus™ Technology have a high VI (viscosity index) already.

8. How will this affect the future of your dino oils?

Pennzoil is only using PurePlus™ base oil in our Pennzoil Platinum® line of premium motor oils. Conventional base oils will remain in other existing formulations that leverage this base.

9. Do Pennzoil products cause engine sludge?

a. No, in fact Pennzoil® motor oils are unsurpassed in their ability to prevent sludge and are even able to help clean up sludge that may have been left behind by lesser oils.
b. Every time your engine is running, by-products from combustion contaminate your engine oil. If the contaminants build up in the oil, they can settle and create sludge and deposits in the engine. Using low quality motor oil, neglecting to change your oil, and other maintenance issues can also lead to sludge forming in your engine.

10. Is there paraffin wax in Pennzoil products?

No, there is not paraffin wax in any Pennzoil products. However, every conventional oil (and most synthetics) on the market today, including Pennzoil, use “paraffinic” base stocks. This is not the same as adding paraffin wax to the oil. Paraffin wax is actually what candles are made of and this is removed in the refining process and sold to the candle makers.

Marketing / Pricing

1. How will this affect the pricing structure of all of your products?

PurePlus™ Base Oil is a Group III product and our finished lubricant products using PurePlus base oil will be competitively priced.

2. How does the PurePlus Technology impact production costs?

We cannot comment on specifics related to production, but it is comparable to traditional methods.

3. Is it your goal to provide a superior product at a competitive price?

Our goal is to offer a high quality synthetic motor oil at a competitive price. Pennzoil Platinum® with PurePlus™ Technology uses high quality PurePlu™s Base Oil and high performance additives, offering complete protection for your engine, without compromise.

4. In regards to your marketing strategy, I respect and appreciate your desire to give your consumers many options – however, I fear that the two-tiered approach with Platinum and Ultra Platinum will force mass-market retailers, due to limited shelf space, to choose only Platinum – making your top-tier Ultra Platinum more difficult and expensive to obtain. As a discriminating consumer who wants the ‘best’ for his vehicles, I would like to know; what are you doing to encourage retailers to offer Ultra Platinum?

Pennzoil Ultra Platinum® Full Synthetic motor oil provides the best cleansing and performance in the Pennzoil family of motor oils and allows us to push the boundaries of our technology. Pennzoil Ultra Platinum is distributed to a variety of retailers and installers across the country and if you are having difficulty finding the motor oil in your area, we encourage you to call us at 1-800-BEST-OIL or search a variety of online retailers.

5. Is Shell marketing the PurePlus™ base oil to independent blenders? (is it possible we will see this base show up in products blended by other manufacturers)

Shell has exclusive marketing rights to GTL base oil produced at the Pearl facility (PurePlus™ base oil), and we are primarily focused on using GTL base oils within our finished lubricants business. There are no plans to offer Shell GTL base oils for spot trading.

6. Why do your products typically cost 30% more at auto parts stores than Walmart?

We do not set the final pricing of our products in the marketplace, that is decided by the retailers and installers.

7. Are the SOPUS Products sold at Walmart exactly the same as the ones sold at AutoZone, O’Reilly, Advance Auto etc..?

Yes, all Pennzoil® products, either packaged or bulk, are formulated exactly the same, and are made in the same plants with the same performance benefits regardless of where they are sold.

8. Is the bulk stuff the same high quality stuff available in retail stores as quick oil change shops?

Yes, all packaged or bulk Pennzoil® products are formulated exactly the same, and are made in the same plants with the same performance benefits regardless of where they are sold. If you are interested in more information, the National Conference on Weights and Measures (NCWM) and the National Institute of Standards and Technology (NIST) have new guidelines that require oil change locations to provide information consumers need to make informed decisions about motor oil. The new guidelines and API’s recently published standard provide consumers with additional information about a bulk motor oil’s brand, viscosity, and performance level.

9. Are there any promotions/specials/coupons offered for the Pennzoil Platinum® with PurePlus™ Technology line of motor oils?

Yes, we often provide our customers with an opportunity to save on Pennzoil® motor oil. Check out to see the latest list of Pennzoil promotions for the latest motor oil coupons, oil change coupons, plus other great motor oil deals and offers.

10. Are 5W-50, 15W-50 and 20W-50 available in the competitively priced Walmart 5 quart jugs?

11. Is Pennzoil Ultra Platinum™ Full Synthetic motor oil with PurePlus™ Technology 0W-20 available in 5 qt. jugs?

We are not currently producing this product in this viscosity grade in 5 qt. jugs.
