12 bolt Moser / Eaton Posi

[RBuhr69]

Moser said to call Eaton, they have never heard of this issue atleast the gentleman i talked with...lol

However, Eaton said more than liklely it is the oil I am using (Lucas). He stopped me mid sentence and said to switch and that should take care of it....

Go with Mobile1 or Shell mineral/petroleum based gear oil and a four ounce bottle of GM friction additive/modifier is also necessary for optimum performance.

with that said.......any advice of exactly what I need? I assume this is not the synthetic version of Mobile1 Gear oil and plain straight oil.......
