I have a Moser 12 bolt with a eaton posi, what weight gear oil do I need? It says use non synthetic, but can I add the GM limited slip additive?

Thanks,

I think I used GM Brand 80-140, I can't remember, but I think that was it.

I'm using the GM LSD additive in my 12-bolt.

I've used Pennzoil 80-90, Torco 85-140 synthetic and Valvoline 85-140 in my Moser...I prefer the Valvoline non-synthetic 85-140 since it helped reduce the driveline "clunk" you get when you go into reverse or going into neutral in slow turns....always use GM original limited slip additive for the best quality anti-chatter for the clutches. Some of the offbrand additive doesn't work as well as GM.
