I was thinking... a lot of performance cars prefer mobil 1... mitsu lancer turbo (19 psi I believe!), porsche turbos, subaru wrx turbos, MB AMG supercharged cars... as well as a bunch of na performance cars.
and they typically use M1 10w-30, an A1 oil. Now, I think its safe to assume that under high temp/high shear, high stress conditions, and A1 oil will not hold up as well. yet, they reccomend A1 mobil1. Why is this????
-any damage that would occur wouldnt be realized until the car is way out of warranty
-the engineers at these companies are idiots or didnt think of it
-it doesnt really matter, tolerances could accept a 20wt oil just fine, so long as its synthetic
Any ideas? I just have had such a strong feeling of necessity for A3 oils (like in my brother's 3000 GT twin turbo), but maybe its not all that necessary...
Any comments?
