what differential are you running?

Myself, I have a locker and used good old conventional Valvoline no additive like Eaton suggested.

Well if you have a detroit locker (like myself), It is a mechanical unit therefore it does not need any additive because it has no clutches. I would use regular old valvoline or mobil one gear oil. Eaton discourages useing sythethitic with a locker.
