Oil Question

BrandonT · 07-09-2011, 08:32 PM

Is that GC still available? At least in the formulation that tested so well? I'll have to look at the M1 0W40 more closely. Aside from uoa what do you know about the formulation? M1 formulations have changed quite a bit over the years.

Mobil1 0w40 has very favorable uoa's as well as it's still a true synthetic vs. all the other mobil 1 formulations ie. 5w30 etc.

Not to mention, it's also standard fill for the GTR, Viper etc, so I'm in good company.

I've tried a few off the shelf synthetics, GC was the best of the bunch so far (my own UOA results).

I've only found GC at autozone.
