Royal Purple Engine Break-In Oil - 1 Quart

Royal Purple Engine Break-In Oil is specifically formulated to provide outstanding wear protection while allowing a quick break-in period for newly built and rebuilt engines. Engine builders have grown increasingly concerned that current engine oils that are API licensed for new cars and trucks do not provide adequate wear protection for freshly built performance engines, particularly those using flat tappet camshafts and lifters. Royal Purple has addressed this issue with Royal Purple® Engine Break-In Oil.Royal Purple Engine Break-In Oil is formulated to provide the critical wear protection needed by the engine valve train and camshaft while allowing new piston rings to quickly seat to the engine cylinder walls. Engine Break-In Oil combines highly refined mineral base oils (preferred for engine break-in) with an advanced additive package containing elevated levels of zinc/phosphorus anti-wear additive to optimize wear protection during the sensitive engine break-in phase.Royal Purple
