I forget the weight, its non-syn Valvoline, whatever Moser recommends. No diff additive since the tru trac doesnt use it. I will see if Moser list a recommondation on their site.

I'm using Amsoil 75w90 in my right now...I will probably go up to 75w115 on the next change. My S60 has a spool so not additive.
