based on the replies here, it should be clear that everyone has an opinion as to who's good or the best, no different than most everything about these cars and 99% of the time it's what they use.
Bottomline is they're all good and there is no difference other than price and choosing between conventional and synthetic. Also, if there's any performace to be had, it's going to come from quanity and viscosity. I know guys that have run synthetic engine oil in their rear ends too.
