VP Engine Assembly Lube is relentlessly tacky to ensure superior clingability. It provides outstanding rust and corrosion protection. Our no-drip, no-run formula won't clog oil ports like other types of engine assembly grease. VP Engine Assembly Lube has a stout base stock that provides superior protection against scuffing, galling and metal transfer during engine assembly and the critical break-in process. It provides exceptional wear protection and is miscible (mixable) with both synthetic and conventional oils. It's an outstanding pre-lube safeguard for engines, including cylinder walls, piston skirts, bearings, camshafts, cam lobes, lifters, wrist pins, and other valve train components.
