i have read several threads and stickies over on nasioc aout what oil is best and all of that.
it seems the top 3 that i see mentioned a lot is mobil 1, german castrol, and rotella. I use synthetic mobil 1 5w-30 extended performance right now. It seems that many people say that the other brands are better.
what group are each of these oils? and what order would you rank them in?
