If you ordered your rear with the Truetrak, you do not need the additive. I would stick to non synthetic gear lube, Moser won't warranty rears that use synthetic. Bob

I just bought a moser 12 bolt w/ the HD eaton posi, does that get additive?

I didn't use additive or synthetic, I thought it came with papers saying not to. I just used 75w90 gear oil.

The Eaton posi uses the additive, the Truetrac does not need it. Bob
