Description
Assembly lube is non-negotiable when building or rebuiling any engine—it protects critical bearing and valve train surfaces during initial startup before oil pressure fully circulates. Lucas Oil’s semi-synthetic formula clings to metal surfaces longer than straight oil, reducing wear on fresh components and ensuring proper lubrication during those critical first moments. This 12-pack gives you enough product for multiple builds or to keep on hand for your shop.
