Comparing a 30wt to a 40wt oil is what I was thinking. I've said this before, for a 0w-40, Mobil 1 is very shear stable. It only drops 1-3cSt at the most and for a 40pt spread, thats good IMO. A Castrol 0w-40 probably would be similar. But I do think GC is a better oil on a direct comparison.quote:
Oooo...please explain that one.
