GM recommends 80w, 80W90 GL5 gear lube, + GM additive #1052271 for limited slip differentials for my KITT. I want to use Royal Purple 75w90 Gear lube to my rear end, will it screw up my rear end? Should I add the additive or not? or use something else?
Royal Purple has the additive built in. Just pour it in and go.

I have been using royal purple for all applications, in all my vehicles. I am running it in my 88 bird, and i did not use any additives. I have the 3.08 W/ posi and it has been fine. I don't have any whining that i have heard about on these cars.
