Castrol Magnatec 0w-20 - 16 Tundra - 6,175 miles *Heavy towing* - 07/20/19 01:28 AM

As a disclaimer, this report is not from my own personal vehicle, it's from a work colleagues I wanted to share; he was curious to see what his results would be on his truck after discussing my own UOA's over the years that I've done on my own vehicles.

This sample on his 2016 Tundra saw some 5,500 miles of towing a 5th Wheel RV weighting in at roughly 14,000 lbs loaded on a vacation trip that saw the Smoky Mountains. Additional details are he changes oil every 5,000 miles since it was was purchased brand new, although this trip he went over a little, along with BG MOA oil additive used every other oil change (this one not being that oil change, but the previous oil change) also using Castrol Magnatec 0w-20 from a bulk tank, and, he is also by no means easy on his vehicles towing, or not towing, as it's his daily driver too.

I'm no expert on UOA's but IMO that's either an excellent engine or an excellent oil....probably both...
I guess the moly is from the BG additive?

So much for the theory that thin oils=heavy engine wear!! This one throws that theory right out the window! Of course, it is Castrol Magnatec, so that's a (good) factor as well. I wish AZ & AAP would give away the 5W30 Magnatec like they did the 5W20 & 0W20-I would use it in EVERYTHING gasoline powered!

Yes, it appears to be from the BG additive: although the calcium value seems a bit low for it, would of been nice to see this sample be the oil change he added it to, instead of the time he skipped it.

The OCI from the manufactures calls for 10,000 miles, not 100% sure if the verbiage in the owners manual calls for less under severe usage that this truck sees (I'm sure it does), I would have to look it up, but knowing him, he's not going to extend the drain interval based on the data provided.

Toyota quality no doubt, my parents having had a few trucks from the domestic side of the competition, after purchasing a 15 Tundra 1794 edition that they have nothing but good things to praise about, have said they won't go back.

I concur, I had mentioned to him in the past, that he may want to consider not using the 0w-20 oil, and switch to a more stout oil of higher viscosity for the towing he planned on doing. What he's towing now is a upgrade from a travel trailer he had before, he wanted something bigger, an RV layout only a 5th wheel could offer, along with a more stable towing experience compared to it's travel trailer counterpart, so when that happened, I had also mentioned to him he may want to consider buying a bigger truck, a diesel one specifically from the big 3, to have something more suited for the job of towing assuming the Tundra wasn't capable of it. Well when he sent me this sample, it was one of those " insert foot in mouth" scenarios, I couldn't of been more wrong in my statements to him.






Some additional information for those interested that I didn't mention, first off this isn't a one use case scenario towing once in a blue moon type thing, hes been towing from day one with it 2-3 times a year with it. He's done a few modifications to both the trailer, and the truck to have a better towing experience most of which are braking upgrades, none of which skew the numbers on the engine oil sample fyi.


The 5th wheel trailer (Chaparral 370FL) has upgraded disc brakes on both axles from the drum brakes it originally had.


Tundra has upgraded rotors & brake pads, and rear air ride suspension (with a PSI gauge built into the center console with a toggle switch to adjust on the fly) to accommodate the extra weight.



Now, the engine holding up is one thing, as far as the transmission holding up longevity wise is another topic up for debate, but in regards to that; I would have to ask him, but I'm certain it was replaced at 30,000 miles with BG Premium Full Synthetic ATF, along with BG ATC Plus Automatic transmission Conditioner additives at the time of replacement. Hes also got a ScanGauge II that he uses to monitor transmission temperature when towing, when towing up steep grades says that transmission temp stays at the 200F mark out of overdrive & Tow/Haul mode, and has no issues towing while maintaining a decent speed even up grades.






A picture is worth a thousand words they say, so here it is, and well for any doubters.

One would assume so, yes, especially since for those that can barely drive a regular car, let a alone something that's X amount in length, and weights X amount have the ability to get behind the wheel with absolutely no experience. Unfortunately, for personal recreational vehicles the laws are relaxed compared to commercial requirements when it comes to towing. It depends on the state on what requires a certain CDL, but for the majority of them, as long as the GVWR (gross vehicle weight rating) between the tow vehicle & trailer doesn't exceed 26,000 lbs you don't need to get a CDL. Without getting into to much detail since there is really that much variation by state, you would have to look it up your self to get all the details, some which require either a commercial drivers license, and some that require a non-commercial license to tow a RV, some examples are you are required to have a CDL if you are towing more than one trailer, like a RV with a boat behind it in certain states, another being you to have one if you are towing something more than 40 feet that requires a non-commercial special drivers license, while in another state you need a commercial CDL for a combined vehicle length exceeding 45 feet. As far as his knowledge regarding the issue, he is well aware of where he can go.

As far as engine wear, that's very good for such use. Probably no surprise; the 5.7L is a great engine from them.

********************

Allow me to now heap shame upon your friend, because frankly, he deserves it.

As far as the load, Tundra's don't have a very large payload capacity (relative to some other brands), and I can assure you that application is over any rating Toyota would approve.

Using their official website: https://www.toyota.com/tundra/2019/features/weights_capacities/8261/8252/8375

Looking at various combinations I see that max payload is 1660 lbs.
Max towing for a CrewMax 4x2 is 10,100lbs and 8,80lbs for 4x4.

Here's the data on the RV: https://coachmenrv.com/fifth-wheels/chaparral/370FL/2149
It is nearly 12k lbs unloaded !!! And the hitch weight is 2200 lbs.
And the unsung hero here are the tires under the truck. I suspect they are way over taxed. Assuming he's using typical P-rated truck tires, he's just asking for problems.

Toyota makes very reliable vehicles and nice trucks. I'm not knocking them. But the use of that truck with that RV is borderline irresponsible and would be a big problem should he cause an accident that injured someone. Airbags are the crutch of the foolish when it comes to payloads. All airbags do in the suspension system is apply the ability to level the truck; they do NOT, IN ANY MANNER, increase the ability of the truck to handle greater loads past the engineering intent. Airbags don't make the frame stronger. Airbags don't make the wheel bearings bigger. Airbags don't make the wheels beefier. No matter how much he wants to rationalize it, he's over-taxing that truck. Can the engine handle it? Probably so. But the chassis was never made to take that kind of load. Google some of the YT vids showing how the Tundra frame flexes under heavy loads, etc. Again - Tundras are great trucks and I like them. But they are NOT appropriate for the load he's put it under and he's risking damage and injury by doing so. Assuming he's got the 4x4 version, then the GVWR of the RV is 65% larger than his max tow rating !!!

As far as I can tell, the CrewMax is only available with the 5.5' bed. By the time the 5vr hitch is installed, it's very likely to be (at best) over the axle and probably actually a slight bit behind. That unloads the front wheels. Not good. Not good at all. And yes, I realize there are cam'ed sliding hitches allowing tighter turns. But you cannot cheat the laws of physics. The pin weight is supposed to be ahead of the axle, not over it or (worse yet) behind it.

Is it impressive that the truck is surviving? Yes.
Am I impressed at your friend's exploits into the RV'ing world? Not in the least. He's risking himself and those he travels around. From a fellow RV'er, please tell him to step up to a truck that befits the RV.

If he has a 4x4, it's probably closer to 65% overloaded to the towing rating. The tow rating is 8800 lbs for a 4x4 in that configuration. It's 10,100 only if it's a 4x2.

Frankly, people whom travel like this tick me off; they are either ignorant (they don't know any better) or arrogant (they know better, but don't care about the consequences). it's irresponsible and dangerous.

Maybe because Mr Newton is concerned about this guys family and the safety of others … he did not go to all that trouble and research … (and as a moderator go off topic) because it was not a serious issue.

I no longer own an RV … but, I live in the middle of “RV world” between RV parks and RV sales … and I’m surely used to seeing big units like that hitched to 350/3500 LT’s … For sure, have never seen what that picture shows …

There is a big difference between making a mistake and gross endangerment of others’ lives.

This is correct. There's a big difference between personality traits ( who likes what brand of lube ...) and egregious, dangerous behavior.


I've been around RVs my entire life, even as a kid. There are people whom know what they are doing, and those who don't.
This is not the OPs fault; it's just his buddies rig and truck. But ....
This is darn dangerous, and should the unthinkable happen, there's going to be a BIG lawsuit. You think Toyota is going to say "Sure - we are fine if you ignore our towing and load limits. After all, we're just some multi-billion-dollar international company with deep pockets. We'll go ahead and cover the punitive damages from the jurors' award because this guy killed a family when his overloaded truck could not handle the situation and crushed the family."

You don't think accidents happen due to overloading? You don't think people are killed every day by overloaded and unsafe vehicles? I just had to deal with a multiple fatality last month where an overloaded class 5 truck could not stop in time, swerved and the load caused him to roll over onto a motorcycle at a stoplight.

The Tundra in this thread is dangerously overloaded. Can the engine pull the load? Yes. Can the engine do it and survive? Apparently so, because the wear is commendable.

Let's remember that the SAE introduced a new towing standard J2807 a few years ago so that fair, accurate, reliable comparisons and contrasts could be made for all vehicles intended to tow. I looked at Toyota's website and could not find any claim to the SAE standard, but I'm fairly sure all the major brands (GM, Ford, Ram, Toyota, Nissan) all use that standard for their truck tow ratings. Don't you think if Toyota could have the tundra tow/haul more, they would rate it higher? After all, the Toyota actually is way low on towing and hauling ratings contrasted to the Big 3. If Toyota states it's Tundra 4x4 towing limit is 8800 lbs, then that's what they mean. It sure as heck isn't anywhere close to 14,000 lbs like the rig we see in the picture! And adding air springs in the rear only levels the truck; it does NOT in any manner increase the load carrying limit.
https://www.sae.org/standards/content/j2807_201602/

Ford, for example, has their SAE call-out right on page two, at the bottom of their towing guide:
https://www.fleet.ford.com/resource...des/Ford_Linc_18RVTTowGuide_r11_Jan4.pdf

Toyota does not specify if they use the SAE standard (at least I could not find it ... but I may have overlooked it)
https://www.toyota.com/t3Portal/document/om-s/OM0C009U/pdf/OM0C009U.pdf
As you can clearly see, starting on page 170, they talk about weights, capacities, limits, etc. One thing that is not immediately obvious but is very critical is the max axle loading. Often will be stated on the vehicle ID label in the door jam. I suspect this example is WAY OVER the axle limits.


But there are times when the glaringly obvious needs to be addressed, and I hope the OP takes the opportunity to tell his buddy that the rest of the world does not appreciate him taking liberties with my family and all those around us. In this case, the off-topic is actually far more important than a boring UOA from a well-running engine.

As a fellow RVer I completely agree with dnewton. That truck is totally wrong for the application and is risking the safety of himself ,his passengers and those around him. By the look of that hitch it’s mounted way too far back on the chassis too. He needs a 1 ton pickup with a diesel. If he ever gets to a DOT stop he is in trouble. Any state trooper should know that Truck is overloaded just by looking at it.

As far as the engine wear, it’s fantastic for the use.

I suspect that the owner is aware of the overloaded condition due to the upgrades he made to the braking system of both the RV and the truck.

Thin oils can protect properly when an engine is properly designed, engineered and produced. Of that there is no question. A great example would be the various gas turbine engines in the aviation world.

However, it's good to note that there are a great many engines that fail early due to oil related issues.

A while back, Shannow posted a great article on the lifespan of internal engine components with upcoming ultra thin oils. The conclusion was that lifespan was increased when the parts were designed properly for the thin oils. The issue remains that many manufacturers fail to do this and continue to use many of the same components they've been using for the last 30+ years.

Hi all. I haven't posted in a while but I must on this one. While I agree that is an impressive UOA the owner of that truck is grossly negligent! That truck is grossly overloaded and he is a danger to everyone on the highway. I pull a 42 foot fifth wheel CAT scaled at 16500 pounds with a 3800 lb pin weight. I also pull it with a 2019 F350 dually with 5250 pound payload rating. Naturally the truck pulls it effortlessly but no way would I pull it with anything less. Fellow RV'ers on here know how people cut you off, slam on the brakes in front of you, etc. NO WAY that truck has enough brake to stop a trailer that big. The rear truck tires are probably overloaded by double their rating, WHEN, not if, one blows out it will be an ugly scene. I promise you someone will get hurt. I implore the OP to have a talk with his buddy and encourage him to search the web and RV owner sites and get some input and advice. Proper tow vehicles are expensive but how much is your families life worth to you?? Rant over lol
