So I recently had my rear end upgraded with strange axles, c clip eliminators, and a eaton truetrac. I know there is some mis-information about what type of gear oil you should run for a truetrac, but the consensus is that it should be free of friction modifier. I happened to stumble upon Torco RGO as it does not have friction modifier in it. It is not a synthetic oil, but it is suited for drag racing applications. I recently saw on the VMP website that you should not run this oil with a truetrac. Any reason why? Originally Truetrac's specified non synthetic oil without friction modifier but the newest owners manual says synthetic is fine as long as it doesnt have friction modifier. Does anyone know why Torco RGO would not be recommended for this diff by VMP?
