Royal Purple Diff oil already has the limited slip additive?
I was picking up an oil filter today at the parts store and saw the Royal Purple Diff fluid, called "Max" something or other.
Anyway, I was looking on the bottle and it says it already has the limited slip additive in it. If I use it, do I need the GM additive? I'm going to be changing the diff fluid soon.
Thanks,
Dan
