Mobil 1 Offers Superior Resistance To Deposits Even At High Temperatures

Mobil 1 is more effective at resisting high temperature deposits than some other leading fully synthetic and semi-synthetic oils. Our test simulates high temperature piston deposit formulation which reduces engine efficiency. The test oil is heated to 285°C and directed onto a rapidly spinning (2500rpm) aluminum disc which is heated to 330°C. This test lasted 3 hours. At the end of the test, we assigned the oil a cleanliness rating out of 100.


I guess it should be of no surprise why M1 0w-40 is used in many high performance cars. The oil has it's shortcomings, but it can certainly handle high temps like most Mobil 1 oils.

330C = 625F. That's hot.

No offense to Pennzoil, but Ultra is nothing new. New to Shell maybe.

Check out the cleanliness photos.

Worthless. 285 C or 330 C is something no engine will see.

So vague. Anybody can cook up their own test that makes their own oil look good. At least Shell tells us they're showing the results of Sequence VG.

I'd like to hear their Sequence IVA results. I don't recall Mobil telling us anything about it. Quaker States proudly displays their IVA results for their used, dino oil.

As long as oil meets GF-4/API SM than the oil scored below < 90 microns on the Seq IVA, which is a low temp, low load test. So what's your point?

This is Shell's 3rd attempt to market an oil that cleans well. Big deal.

It's not worthless when you have a high performance engine! It's worth a [censored] of a lot, which is why I said high performance engines . In your grocery getter, no it's not worth it.

It is worthless when you're testing for conditions that don't happen. The least they could do is find some more sane temps like 150C. They actually do that in the second test, but they don't tells us what kind of engine test it is.

AFAIK, API doesn't police oils as well as I'd think it should.

There will be some spots in high performance or turbo'd engines that may see higher temps than even that. If high temp deposits are a big concern M1 is easily a reliable choice. For the sake of competition and advancement hopefully Penzoil/Shell show competative and even superior.

Cool post Buster, thanks.

I think they do that in another video.

Your turbocharger won't have the benefit of fresh oil. It's going to be filled with CC byproducts, fuel, and wear metals.

Combustion, that's a really cold process.

but then we couldn't such nice pictures at higher temperatures. I'm just saying there are severe flaws with the test. They're just going to show you something that looks nice and not necessarily what's representative of the real world.

EDIT: I am forgetting the obvious. The oil was heated to 285 C. You won't see those temps at the sump. I knew there was a reason why I didn't think of the CC area.

There's some photo that shows how esters did vs. PAO and other base stocks @ some ungodly temp. Naturally the ester was better. They didn't show the comparison at any sensible temp ..even 150C to show how they probably looked alike.

You're going to show what gives your formulation distinction, whether or not it's really significant.

So, M1 0w-40 has a flash point of 230C, yet nothing happens even at 330C?

From my chats with TooSlick, what that shows is how cleanly it flashes regarding deposits and residue. This is a major advantage of synthetic over dino. A dino's flash point might be the same, but they leave (more) [censored] behind.

The temporary combustion that occurs during flash point tests occurs because the "air/fuel" ratio just reaches combustible. One can heat any oil to a temp above its "flash point" by preventing the air/fuel ratio from becoming combustible, such as by making it too rich or too lean. I've done this personally. Oil tankers keep their tanks too rich to combust. Anyhow, Mobil didn't provide much detail about the test in that link, so I don't even know if their was combustion going on or not, but I doubt it because I've never heard of that kind of high temp deposit test.
