oils. This puts flat tappet engines in danger of flat cams and damaged lifters. GM did market a product named E.O.S. or engine
oil supplement that replaced this zink for newly rebuilt flat
tappet engines. Does anyone know of another product that might
work in place of this. I have been told that you can use oils designed for diesels but zink is also being eliminated in these
oils. | | |
