In short... thin is in... top 10 ranked oils are 30 grades...

So, as you can see, oil viscosity plays no particular role in an oil’s wear protection capability. As mentioned above, an oil’s wear protection capability is determined by its base oil and its additive package “as a whole”, with the primary emphasis on the additive package, which contains the extreme pressure components.

Wear protection reference categories are:

• Over 105,000 psi = INCREDIBLE wear protection

• 90,000 to 105,000 psi = OUTSTANDING wear protection

• 75,000 to 90,000 psi = GOOD wear protection

• 60,000 to 75,000 psi = MODEST wear protection

• Below 60,000 psi = UNDESIRABLE wear protection

All the oils were tested at a representative operational temperature of 230*F.

The HIGHER the psi value, the BETTER the Wear Protection.

1. 5W30 Pennzoil Ultra, API SM synthetic = 115,612 psi
I have not been able to find this oil with the latest API SN certification. The bottle says, “No leading synthetic oil provides better wear protection”. For once, a product’s hype turns out to be true. And this oil provides MORE THAN TWICE as much wear protection as the lowest ranked oil on this list.
Chrysler is so impressed with Pennzoil Ultra, that they selected the 0W40 version of it as the only Factory Fill oil for their latest 8.4L, 640 HP, V-10, 200+ mph, Dodge SRT Viper.
zinc = 806 ppm
phosphorus = 812 ppm
moly = 66 ppm
calcium = 3,011 ppm
TBN = 10.3

2. “Oil Extreme concentrate” added to 5W30 Pennzoil Ultra, API SM synthetic = 111,570 psi
This oil on its own WITHOUT the “Oil Extreme concentrate” added to it, has a wear protection capability of 115,612 psi, and is ranked 1st. But, with 2.0 OZ of concentrate added per qt, which is the amount intended for racing, its wear protection capability “WENT DOWN 3.5%”.
zinc = TBD
phosphorus = TBD.
moly = TBD
calcium = TBD
TBN = TBD

3. “Oil Extreme concentrate” added to 10W30 Brad Penn, Penn Grade 1 semi-synthetic = 111,061psi
This oil on its own WITHOUT the “Oil Extreme concentrate” added to it, has a wear protection capability of only 71,206 psi, and is ranked 88th. But, with 2.0 OZ of concentrate added per qt, which is the amount intended for racing, its wear protection capability “WENT UP A BREATH TAKING 56%”.
zinc = TBD
phosphorus = TBD.
moly = TBD
calcium = TBD
TBN = TBD

4. 5W30 Oil Extreme, API SM synthetic (per the Oil Company, even though synthetic wording is not shown on the label) = 110,286 psi
The Company claims this oil contains their proprietary formula of calcium petroleum sulfontate EP (Extreme Pressure) technology that is NOT found in any other motor oil. They also claim that it will provide 5 to 7 more HP, 7 to 10% better fuel mileage, cut engine wear in half, and will extend drain intervals two or three times safely. This oil is endorsed and promoted by Tech Author David Vizard. And he was so impressed by this oil’s performance that he also became a share holder in the Company. The results from the “Dynamic Wear Testing Under Load” performed here, fully supports their claim regarding wear protection. So, their hype about that, turned out to be absolutely true. And since this oil beat every high zinc oil I’ve ever tested, it also proved another one of their claims, that using zinc as the primary anti-wear component, is outdated technology.
zinc = 765 ppm
phosphorus = 624 ppm
moly = 52 ppm
calcium = 7,652 ppm
TBN = 23.2

5. 10W30 Lucas Racing Only synthetic = 106,505 psi
zinc = 2642 ppm
phosphorus = 3489 ppm
moly = 1764 ppm
calcium = 2,929 ppm
TBN = 9.0
NOTE: This oil is suitable for short term racing use only, and is not suitable for street use.

6. 5W30 Mobil 1, API SN synthetic = 105,875 psi
zinc = 801 ppm
phosphorus = 842 ppm
moly = 112 ppm
calcium = 799 ppm
TBN = 7.5

7. “Oil Extreme concentrate” added to 10W30 Lucas Hot Rod & Classic Hi-Performance Oil conventional = 105,758 psi
This oil on its own WITHOUT the “Oil Extreme concentrate” added to it, has a wear protection capability of only 62,538 psi, and is ranked 104th. But, with 2.0 OZ of concentrate added per qt, which is the amount intended for racing, its wear protection capability “WENT UP A MIND BLOWING 69%”.
zinc = TBD
phosphorus = TBD.
moly = TBD
calcium = TBD
TBN = TBD

8. 0W30 Amsoil Signature Series 25,000 miles, API SN synthetic = 105,008 psi
zinc = 824 ppm
phosphorus = 960 ppm
moly = 161 ppm
calcium = 3,354 ppm
TBN = 11.4

9. 10W30 Valvoline NSL (Not Street Legal) Conventional Racing Oil = 103,846 psi
zinc = 1669 ppm
phosphorus = 1518 ppm
moly = 784 ppm
calcium = 1,607 ppm
TBN = 4.4
NOTE: This oil is suitable for short term racing use only, and is not suitable for street use.

10. 5W50 Motorcraft, API SN synthetic = 103,517 psi
zinc = 606 ppm
phosphorus = 742 ppm
moly = 28 ppm
calcium = 1,710 ppm
TBN = 6.7

11. 10W30 Valvoline VR1 Conventional Racing Oil (silver bottle) = 103,505 psi
zinc = 1472 ppm
phosphorus = 1544 ppm
moly = 3 ppm
calcium = 2,707 ppm
TBN = 7.6

12. 5W30 Amsoil Series 3000 Heavy Duty Diesel Oil synthetic, API CI-4 PLUS, CF, SL, ACEA A3/B3, E2, E3, E5, E7 = 102,642 psi
This is BY FAR, the highest ranked Diesel oil I have ever tested. This oil is Engineered for Diesel engines not equipped with Diesel particulate filters (DPF). Amsoil says this oil delivers better wear protection than other popular Diesel oils. And in this case, their hype is absolutely true. They also say it effectively reduces fuel consumption, with its advanced fuel efficient formula. This oil costs $11.15 per quart in the 2013 Amsoil Factory Direct Retail Catalog, which is 10% more than Amsoil’s 5W40 Premium Synthetic Diesel Oil. So, in this case, you pay only 10% more for the Amsoil Series 3000 Heavy Duty Diesel Oil, but you get a whopping 33% more wear protection than you get with the Amsoil’s 5W40 Premium Synthetic Diesel Oil. Money very well spent, if you run a Diesel oil intended for engines not equipped with Diesel particulate filters. The next highest ranked Diesel oil only ranks a very unimpressive 54th out of the 118 oils I’ve tested so far. So, this 5W30 Amsoil Series 3000 Heavy Duty Diesel Oil is in a class of its own, among all the Diesel oils I have tested.

13. “Oil Extreme concentrate” added to 5W30 Mobil 1, API SN synthetic = 102,059 psi
This oil on its own WITHOUT the “Oil Extreme concentrate” added to it, has a wear protection capability of 105,875 psi, and is ranked 6th. But, with 2.0 OZ of concentrate added per qt, which is the amount intended for racing, its wear protection capability “WENT DOWN 3.6%”.
zinc = TBD
phosphorus = TBD.
moly = TBD
calcium = TBD

14. 10W30 Valvoline VR1 Synthetic Racing Oil, API SL (black bottle) = 101,139 psi
zinc = 1180 ppm
phosphorus = 1112 ppm
moly = 162 ppm
calcium = 2,664 ppm
TBN = 7.4

15. “Oil Extreme concentrate” added to 5W30 Pennzoil, API SN conventional, yellow bottle = 100,252 psi
This oil on its own WITHOUT the “Oil Extreme concentrate” added to it, has a wear protection capability of only 76,989 psi, and is ranked 69th. But, with 1.5 OZ of concentrate added per qt, which is the bottle’s instruction for street driven vehicles, its wear protection capability “WENT UP A WHOPPING 30%”.
zinc = 970 ppm
phosphorus = 749 ppm, this value is 91 ppm lower than the basic oil because the concentrate has less phosphorus in it, which diluted the overall ppm count of the mixture.
moly = 285 ppm
calcium = 4,443 ppm
TBN = 18.8

*************** MOTOR OIL VISCOSITY SELECTION **************

THE BENEFITS OF USING THINNER OIL:

• Thinner oil flows quicker at cold start-up to begin lubricating critical engine components much more quickly than thicker oil can. Most engine wear takes place during cold start-up before oil flow can reach all the components. So, quicker flowing thinner oil will help reduce start-up engine wear, which is actually reducing wear overall.

• The more free flowing thinner oil at cold start-up, is also much less likely to cause the oil filter bypass to open up, compared to thicker oil. Of course if the bypass opened up, that would allow unfiltered oil to be pumped through the engine. The colder the ambient temperature, and the more rpm used when the engine is cold, the more important this becomes.

• Thinner oil also flows more at normal operating temperatures. And oil FLOW is lubrication, but oil pressure is NOT lubrication. Oil pressure is only a measurement of resistance to flow. Running thicker oil just to up the oil pressure is the wrong thing to do, because that only reduces oil flow/lubrication. Oil pressure in and of itself, is NOT what we are after.

• The more free flowing thinner oil will also drain back to the oil pan quicker than thicker oil. So, thinner oil can help maintain a higher oil level in the oil pan during operation, which keeps the oil pump pickup from possibly sucking air during braking and cornering.

• The old rule of thumb that we should have at least 10 psi for every 1,000 rpm is perfectly fine. Running thicker oil to achieve more pressure than that, will simply reduce oil flow for no good reason. It is best to run the thinnest oil we can, that will still maintain at least the rule of thumb oil pressure. And one of the benefits of running a high volume oil pump, is that it will allow us to enjoy all the benefits of running thinner oil, while still maintaining sufficient oil pressure. A high volume oil pump/thinner oil combo is preferred over running a standard volume oil pump/thicker oil combo. Because oil “flow” is our goal for ideal oiling, NOT simply high oil pressure.

• Oil flow is what carries heat away from internal engine components. Those engine components are DIRECTLY oil cooled, but only INdirectly water cooled. And better flowing thinner oil will keep critical engine components cooler because it carries heat away faster. If you run thicker oil than needed, you will be driving up engine component temps.

• Thinner oil will typically increase HP because of less viscous drag and reduced pumping losses, compared to thicker oils. That is why very serious Race efforts will generally use watery thin oils in their engines. But, an exception to this increase in HP would be in high rpm hydraulic lifter engines, where thinner oil can allow the lifters to bleed-off at higher rpm. In everyday street vehicles, where fuel consumption is a consideration, thinner oils will also typically increase fuel economy. The majority of new cars sold in the U.S. now call for 5W20 specifically for increased fuel economy. And now Diesel trucks are increasingly calling for 5W30, also for fuel economy improvement.

• With the exception of high rpm hydraulic lifter engines, almost no engine should ever need to run oil thicker than a multi-viscosity 30 weight. The lower the first number cold viscosity rating, the better the cold flow. For example, 0W30 flows WAY better cold than 20W50. And 0W30 flows WAY better cold than straight 30wt, which is horrible for cold start-up flow and should be avoided at all cost. And the lower the second number hot viscosity rating, the better the hot flow. For example, 0W30 flows WAY better hot than 20W50.

• Thicker oil DOES NOT automatically provide better wear protection than thinner oils. Extensive “dynamic wear testing under load” of dozens and dozens of motor oils, has shown that the base oil and its additive package “as a whole”, is what determines an oil’s wear protection capability, NOT its viscosity. For example, some 5W20 oils have proven to provide OUTSTANDING wear protection, while some 15W50 oils have only been able to provide MODEST wear protection. So, do not run thicker oil under the false assumption that it can provide better wear protection for our engines.

• BOTTOM LINE: Thinner oils are better for most engine lubrication needs.

As per the other times that this has been posted (this week even), he's using one parameter that if you reach it you have already failed in lubricating your engine to state that any given oil is better than any other.

His testing method is not representative of any place in any engine that you or I are ever going to see.

And his conclusions have absolutely nothing to do with the parameter of choice by which he ranks them.

Well, that's the "pseudoscientific method" for you. Certain people, including the author of that study, obviously have problems with the way the API, ACEA, ILSAC, and so forth test lubricants. They're dissatisfied with academically accepted standards, since they don't give the results that they wish to see (i.e. a marked difference between two SN/GF-5 lubes). So, they invent some sort of test that provides the results they wish to see.

True it's been posted but this is the motorcycle version because some of us don't bother
with the cager threads...

Mercy Mr. or Mrs.BEMEch why don't you challenge *him* and his testing methods or come up
with your own test that wows us???

There's a bunch of people called SAE, API, ACEA, JASO, not to mention OEMs, that seem to be doing OK at the present time...and they don't use the one armed bandit or shill for oil additives...

OMG, posted again? Where are the mods, this will be at the top of every section soon!

Yeah, BLS thinks the 'cagers' need help understanding oil or can't appreciate all this wonderful PSI garbage data? Thanks a lot. With that kind of obvious derision as a start, here we go again down a long road of snortin' and a-puffin' about what we can tell YOU, you ignorant car drivers.

I'd stock up on Pennzoil Ultra promo items at this point. Hats, shirt, key chains... would be nice collectibles.

This oil is already an oddity to find on store shelves.

We'd be lucky if they start incorporating GTL basestock into QSUD and Platinum...

Well, I missed the other threads since they weren't titled as clearly.

While it only looks at one aspect, it corresponds to a lot of other things that have been published in different reports and the way technology is going.

Remember all the predictions of doom when CJ-4 came in?, Where are they now? Things other than ZDDP have shown us results.

We often look at simple results on an oil analysis and think we are seeing the whole picture. But we can only see the values of certain elements, and not even know what compositions they are. "Calcium" can be in many forms. Molakule could expand much more on this aspect than I can.
