I am planning to do a rear end "gear oil change".
Previously, I used to get everything from GM - namely the rear gear lube + one bottle of "Limited Slip" additive.
Is this additive available from the local Auto Parts Store - in an "aftermarket" brand name?
If I decide to get other-than-GM Lube - I am thinking maybe some "lighter-in-color" Valvoline. I wish to ask the rated viscosity - should it be 80w90?
Many Thanks !!!
