Despite all the godly PAO and esters and whatnot the results are not what you would expect.


Cooking an oil at over 700°F in a glass flask and visually evaluating the sludge formed is utterly meaningless. The conditions are not even close to an automotive engine and no correlation to engine performance has been established. No scientific conclusions whatsoever can be drawn from such testing, and the results are more apt to mislead than guide.

The engine and/or fleet tests conducted for certification under API, ILSAC, and ACEA standards are run is actual engines under very severe conditions with standardized equipment and procedures and all variables under control. These are the only scientifically valid methods for evaluating motor oil performance in engines. Everything else is marketing.

Your best guide for selecting motor oils is certification under the official specifications relevant to your engine/environment/driving pattern.

The exact deposit composition for each oil is something which would require lots of testing to determine, but really, what's the point? Your engine is going to have much bigger problems than sludge if your oil sees temperatures over 500*F, heck over 300*F usually spells trouble. The standard NOACK test is as extreme as any test needs to be.

Ester based oils were first developed for gas turbine engines where the operating temperatures are substantially higher than piston engines. In those applications esters are the only choice, but in road going piston engines other factors are much more important than ultra-high temperature stability.

Eventhough there may be no relevance to actual engine operation, it's odd that similarly specced oils react so differently to heat.

As far as marketing goes, I don't think the test favoured any brand or specific oil and was more of an armchair science project.


700°F is beyond the thermal stability on many components in motor oil, and the rate of oxidation is thousands of time higher than what an engine sees. The chemical reactions that take place under these conditions bear no resemblance to the reactions taking place in an engine. An additive that out performs all others in an engine may fall apart at 700°F, but who cares if it never sees those temperatures. If you ran the test at 1,000°F for ten hours, all of the oils would turn to carbon, but that doesn't mean they are all the same.

My marketing comment refers to companies that use non-standard tests to promote their products.

Before you know it, companies will be using machines made for testing gear oils to market their engine oils. Oh wait, nevermind! LOL

Try making a whole drift/track day and you'll see what's the difference between PAO/Ester high-priced oils and the group 3 ¨synthetics¨.


I'll bite on this one. I've had my car on track for about 45 days this year alone. Nobody would accuse me of being a "granny" driver. I've run M1 0W40, RL 0W30, and RL 20WT Race oil. I can't tell a difference between them. What am I doing wrong? What big difference should I be noticing?

Quite well formulated, I completly agree.

It is proved that all kind of tests on engine oils, which consist of cooking above 700F, friction machines etc. are irrelevant to a real engine oil test, don't prove or disprove anything, create conditions that have nothing to do with the lubrication of an engine.

It's your car man, you can use whatever you want. If you think that holding an engine near the rev. limiter for hours in a 40C summer day is the same with a 7$ per cuart oil and with a 20$ per cuart one, it's your choice.

I do drive in the summer here in Texas, where it can easily be 100F+ ambient and well over 120F+ on the asphalt. So far my motors have all held together just fine. I've got about 30K track miles on this one.

You clearly stated that the difference was big and noticeable. What should I be feeling for when I'm out on the track this weekend?

How does anyone pretend to know the composition of Mobil 1 0W-40? It may indeed contain group III+, but I bet a tidy sum that it's at least a blend of III+ and IV...

Just like how they pretend to know the composition of most oils: Repetition.

Repetition.


LOL! Not that it matters anyway. The oil has an arms-long list of certs and approvals, holds its grade, has a very low NOACK and lasts an extremely long time in use. It is an exceptional lubricant.

What are you, a Mobil 1 fanboy? Keep that stuff to yourself. Some of us don't have blind faith in everything the big companies tell us.

Now, if you'll excuse me, I have to go buy this oil I read about on the Internet.

Turbokick, I'm curious of the answer to this as well. I've never notice a real world difference between the two...and I'm a bit inclined to believe I have an engine that produces quite a bit more power than 95% of the cars on a road coarse track.
