Mobil 1 oil weight

[Ameer Antar]

To me, I think this is a matter of personal preference like coke vs. pepsi. I'm
surprised to only hear a couple opinions though...
These are all called fully synthetic. I'm know that Penzoil is PAO-based too,
but I seriously doubt that it's 100% PAO due to the expense. I just have a hard
time believing that one company is selling oil that's so much better and
expensive to make for about the same price as another.
 
To me, the important thing is how it performs. Just comparing specs for 5w30
Mobil 1 and Penzoil Platinum, the Mobil 1 specs are a little bit better:
 
Pour point: M1: -54C, PP: -39C
Flash point: M1: 230C, PP: 196C 
 
The flash point is definitely important for a turbo motor. And, looking at the
viscosity, M1 is actually thicker at both 40 and 100C.
 
I think this is really a preference issue. I doubt most of us will actually
feel the difference, but I think it's good to know that what you're getting is
the best option within reason... I mean I think $5-7 a quart is a lot of money,
and I'm not about to special order any oil. 
 
Just my 2 cents.

 No, check bobistheoilguy forums. You're wrong. Mobil 1, in any formulation, is
NOT PAO based any longer.

Show me a current sample and spectrophotometry results to back it up like the
guys on BITOG.

The quote you have below- "Mobil 1 with SuperSyn uses high-performance
fluids, __including__ polyalphaolefins (PAOs)"

That's the big out- "including," meaning that it is not the only base, which it
used to be.
