13. What gear oil should I use?

You can find this in the owner's manual. Otherwise, 75w90 or 80w90 will work fine. It is not necessary to use synthetic oil. Also if you have an auburn carrier you will need the limited slip additive.

I would stay away from synthetic gear lube. 80w90 or 85w90 is what we use, along with posi additive. The Truetracs do not need posi additive for those of you reading this, who have a Truetrac. Bob
