Any 80W90 or 85W140 But try and stick with the GM friction modifire.

Even though it is a 7$ bottle of gear lube with white lithium grease mixed into it LOL but works better than that positraxx swill from auto parts stores.

The posi will just chatter around slow corners at all if u dont use any period.

The guys by me swear by Royal Purple, I've used the standard valvoline synthetic with the GM additive. I've had no problems, but I don't drag race.

I will agree with others and say from experience use the GM additive and dont' waste your time trying other stuff. I threw it in with some mobil 1 and never a problem.

Redline is realy good.

Redline is realy good.

I agree. Used this stuff for years. It has the friction modifier already blended in.
