Amsoil ISO100 Compressor Oil
It works great for compressors and suckers(vacuum pumps) for me. It absorbs and deals with water far better than any other oils I've used in those roles.
A town I know, the guy who takes care of the sewage system, I talked him into trying the Amsoil in their sewage lift pumps, and he was thrilled with the results, the dino would turn white and foamy in a month, he's getting 3 months on Amsoil and it's still not dead. It's paying for itself, apparently the pumps are lasting longer too.
