    GM limited slip additive and 2 quarts of a good 75w-90.

    Every 25K miles or so would be a decent interval.

    Yeah go with what Mr. Luos said. Although I thought you could go a lot longer than 25k miles

    For the power our cars have & the vast amount of power our ls1's can be modded to have, the rearend they "equipped" us with is a joke!

    I think the recommended interval is 7000 miles if you can believe that.

    You can get the GM addative at the stealership or you can get pretty much its equivalent at Napa as well as the gasket, permatex sealant, 75/90 gear oil. I use Valvoline in mine.

    For the stock rear end....and a mostly stock car.


    Two quarts Mobil 1 75w-90 and GM additive from the stealership. Any gasket that will fit will do....with RTV (gasket maker) on it.

    Use a good synthetic oil such as Royal Purple, Then you will not need the additive.

    I do mine every spring when the car comes out of the storage unit. Mobil 1 75w90 and what ever LSD additive I can find at the parts store (usually kendal or atp.)
