Re: Differential fluid (foundvettelifeisgood)
Two bottles of GM differential lube, 1 bottle of limited-slip additive(some people say 2, so go with what your heart tells you...)
If you need part numbers, I have the bottles in my shed. But you should be able to just tell the parts counter at the dealer what you want and you'll be fine.

Re: Differential fluid (foundvettelifeisgood)
From empty I'll add one 4 oz. tube of a Sta Lube product called Equa Torque, a posi/limited slip additive that meets GM, FOrd and everybody else's spec, and then pump in the oil--80W90 limited slip gear oil (the Sta-Lube stuff in the pump jug) until it dribbles out the filler hole. The limited slip oil AND Equa Torque might be overkill, but I've never had problems with this combo. Button it up and you're done. Take a slow drive around the block to mix it up good and then hammer on it.
