I just put Motul Gear in my Chevy truck and I noticed it says on the label that it is for racing diffs and transmissions. I was worried I accidently got race only lube, but after some research I verified it is for road vehicles too. Unlike racing motor oils which trade some traits for more important short term needs, it seems that racing gear lubes have longevity too. Are most racing diff and trans lubes streetable? Know of any that aren't?
