Came across this from engineering explained on youtube. Some may find it interesting so ill share it here
Not all engine oils are created equal

Was just about to post it here. Still watching, about halfway through. Thanks for posting!
AA+ video. Thanks for posting
It would be nice if they called out which oil failed those tests.
Mobil 1 controls the narrative. A 120,000 mile test on a dyno… Hmmm.
True with m1 ap they did 500k mile tests at 20k oil changes
Hey, a test on one oil, sponsored by the oil maker, in an engine that is easy on oil and isn't made anymore with purposefully altered environmental factors that are not typically present in most scenarios.
HOWEVER, very informative video. Thanks.

Leaves out a lot of very important variables. Air cleanliness is a factor since the silica in the oil scuffs the surfaces a ton which the engines don't seem to get as just stand there and not get driven on real roads or at least get fed dirty air. They didn't include any of that whatsoever, the oil filter is also important. Oil that is constantly hot is going to clean better and also be in a tribofilm state which reduces wear significantly and heavier yet very stable loads are also helping the engine. It's varying engine loads, oil pressure, and engine speed that account for wear. And they didn't state what engine rpm the Toyota was ran at and the variable oil pump pressure and rpm data is readily available so they could just be at the sweet spot in the highest rpm with the least oil pressure to maximize either efficiency by less pressure and less drag or better wear numbers with more oil pressure
And if I'm not mistaken that Toyota is supposed to get 0w-16 and 0w-20 only once and must return to 0w-16 the next time yet there is no 0w-16 EP. There is only 0w-20 and thicker so they had to have ran either that or thicker still as they also gave zero mention of what viscosity of M1 EP they used in the Toyota as you can't assume they used the required 0w-16 as that doesn't exist and they didn't mention a disclaimer about using the wrong oil which they pretty much did. And they also gave zero mention to the speed the vehicle was driving at on the dynamometer as it could've been a more constant 70 mph which racks up that mileage faster than real world average vehicle speed per engine running hour which are like 20-40 mph in the real world as the vast majority fall into that severe category.
They also say that in their "independent testing" that the oil doesn't oxidize as much as compared to the rest in the industry but are they counting the extreme fuel dilution to lower the viscosity of the oxidized oil? The video is hogwash that no one in their right mind would take beyond a grain of salt. No one should believe such one sided baloney from a manufactures doctored testing standard which gave no real information and data being given/excluded to the public. But sadly a lot of normal consumers are gonna be amazed by the few difficult things and think that's the whole story and believe it. Mobil also gave no mention that they don't guarantee going 2x over the 10k interval and that the product user should read what it says on the bottle and also follow manufacturer maintenance intervals regardless of what they claim but they don't. They heavily imply that you should leave it in there for 20k miles until something bad happens and if you try to go after Mobil after the dealer said "lol should've done 10k intervals tops not 20K" Mobil will hit you with the "should've read what it said on the back of the bottle in fine small print which we know full well no one actually does so we get away with fooling you since the disclaimer tells you to not do what we advertised to you on the front in big bold font since we know that no car brand says to go 20k miles in their intervals" and leave you SOL with the bill.
I can't find any of Mobil's testing standard information or any actual figures of the results. They just give some generic charts with no meaningful data points on the axes.

They still have doctored testing procedures and that's not at all indicative of the real world.
The dyno allows them to vary the load during the test.

How else are you going to control operating conditions for two separate vehicles? While it would be nice if they did a fleet test, there are too many variables. Doing simulated daily driving on a dyno is as controlled as you are going to get with the oil being the only variable.
Not exactly. Your looking at only one test rather than all of them as a whole.

Thanks for posting this! Very informative.
But load is different than stop and go, idling and cold starts.
The test fuel is designed to encourage sludge which would increase viscosity. Heavy dilution on the test fuel would generate higher amounts of oxidative thickening. That is the purpose of this particular test. Perhaps there's another test which measures how much an oil falls out of grade?
They don't heavily imply anything. There's a lot of talk on this board of oils which meet spec and oils which perform measurably better than the minimum required of the spec. Basically this video was about how M1 pushes the performance of their product above the "good enough to meet spec" threshold.
Yeah towing and such but at what speed, what level of towing weight simulated, and frequency. They don't say what degree of the modes they use in their data, is it evenly split or is it one over the other? If they tow only once for 30 minutes and never again during that run they can still undeniably clam they still tested towing but not give data as to how much it accounted for in the overall data but use it as a prop to their narrative. It's best to not be naive when it comes to one sided data with no real information. They give no real definable criteria in their testing standards and procedures just generic info.
It is but one test out of a battery of tests and the dyno test isn't even required to meet API SP.
