Mobil 1 claims that their Mobil 1 fully synthetic oil can withstand temps up to 500 degrees fahrenheit.

Does anyone know if Mobil has actually tested this and made video of the test?

Another question I have is have any other manf. of fully synthetic oil made a claim close to this?

I use M1 exclusively in my turbo cars. I promise that the turbocharger shaft, reaches 500 degrees F where it comes in contact with oil, as the metal's color temperature is solidly straw at the bearings edge, tapering to brown near the turbine side seal. Which is 500 deg F.

No coking of oil using M1.


People who count on their fingers should maintain a discreet silence.

Is the flashpoint of an oil also relevant? Turbo might be 500 degrees but that doesn't mean the oil is at 500 degrees? One of the attributes of Delvac 5w40 CJ4 is it had a relatively higher flashpoint than others (assuming due to PAO content) which I liked for the turbo diesel F550. Thanks for sharing.

Not sure what this is doing in the diesel oil part of bitog, but OK.
Mobil has several videos on youtube where they talk about turbo bearings and heat.
Yet, understand Ford says you can run conventional GroupII dino oil in Ecoboost engines, and they are proven to last just fine, with water cooling and oil cooling critical at shutdown time especially.

500F is 260C, so this is not too far from the temp at which NOACK testing is performed (250C).
I guess the big difference would be that anything that goes to gas in NOACK testing will be carried away by the air flowing over the pan while it would be confined near a turbo and likely go back to liquid after flowing back towards cooler oil...???

Mobil 1 says now it can withstand temps up to 500 degrees. I remember years ago they used to say up to 400 degrees. I can't recall what year they changed it.

When Pennzoil first introduced the PurePlus GTL formulations, their website talked about withstanding temps up to 400 degrees! I thought it was interesting because Mobil used to be about the only one saying that. By that time, Mobil had already saying up to 500 degrees.
Looking around the Pennzoil now, I don't see any mention of it anymore.

Same thing with Valvoline, a few years ago, I remember seeing on their website where they said their synthetics withstand up to 400 degrees. Now, I don't see it anymore

It looks like Pennzoil and Valvoline have backed down on their claims. Mobil is still saying up to 500 degrees.

PPPP 10W-30s last published NOACK was 4.7%. Being that stable, its gotta be able to withstand some heat. Thats why I run it in the WRX, instead of the 5W-30 it calls for.

Personally I'd take these claims with a huge dollop of salt.

Can the oil withstand 500F (260C) momentarily in a relatively oxygen free environment, like when it zips through something like a turbo bearing? Perhaps. But for sustained periods with lots of hot, oxygen rich blow-by around? I very much doubt it.

Also bear in mind that even if the PAO base could take this level of heat, any ZDDP or HSD VII in the oil markedly cannot without breaking down.

^^This^^

What does "withstand" mean? Momentarily? Sustained? Oxidation? Volatility? Flash point?

Every engine oil in every engine on the road hits this at some stage in the ring belt. And it does it for many thousands of km, and many hundreds of hours.

Therefore just about everything that you see on the shelf at walmart also "withstands 500F temperatures'

That is true, apparently backed up by Angela's statements at the 17:00 minutes point in:

I actually didn't know that a vehicle like my 2000 F150 would get really hot,say over 200 degrees. Now my zero turn mower is what I thought would get much hotter than my truck. That's why I use Mobil 1 10w40 in my commercial zero turn mower. I have always used Mobil 1 5w30 in my truck,just because I like using fully synthetic oil.
