CAT market an NLGI 1.5 grease that's 5% moly, calcium sulfonate complex soap among other EP additives and very good.

Pop into a Westrac, they should have it on the shelf in standard tubes. I think it's called Ultra 5 ?

My favourite NLGI #2 grease is their Desert Gold, a full synthetic, calcium sulfonate 5% moly grease

Calcium sulfonate soaps resist water washout and rust better than any other soap base.
