Zinc Rich Oil for Flat Tappet Cams
My suggestion is use Schaeffer racing oil or their 7000 series that is fortified with tons of Moly, this company is the oldest USA oil company that is little known outside the industrial industries or people in the know, they spent money on product to reduce downtime and repair in industry and kept their product priced right not wasting it on sponsorship and mass qty advertising. Trust me and ask around those in the know will tell you nothing but great things, me included.
