Mobil 1 oil weight

[Ameer Antar]

I think you're talking about Mobil Clean. Mobil 1 is still PAO-based. You're
right about the GF designation, it's not the same as grouping. But I think
anything based on PAO's will be group IV, and group V are ester based. Group
III is regular oil processed to perform like PAO's. This is a pretty
informative site: http://www.peterverdonedesigns.com/motoroil.htm
 
Just to be sure I checked with the Mobil website and here's the answer: 
 
Q: Is Mobil 1 with SuperSyn Technology a fully synthetic motor oil?

A: Yes, it is. To meet the demanding requirements of today's specifications
(and our customers' expectations), Mobil 1 with SuperSyn uses high-performance
fluids, including polyalphaolefins (PAOs), along with a proprietary system of
additives. Each Mobil 1 with SuperSyn viscosity grade uses a unique combination
of synthetic fluids and selected additives in order to tailor the viscosity
grade to its specific application.

 No, Mobil 1 is not PAO based. You're about a year old on your info if you're
showing that. That was the big news on bobistheoilguy forum last year.

Pennzoil Platinum's original formulation was group V, never was group IV, now
is group III, which is the same crap they call "synthetic" that is the basis of
current Mobil 1, Castrol Syntec (exc. German Castrol 10W30) and pretty much all
others save Redline and some other esoteric oils.

I don't know what this GF rating you're talking about.

Splitting hairs, I know, but I'm not spending $4-5 per qt. for "fake synthetic"
oil- at that point, I might as well use whatever's cheapest. That's why I have
a small stockpile of "real synthetic" oil that I use for the turbo engines.
Once that runs out, the STi is getting Redline 10W30.
