Royal Purple Royal Purple Engine Break-in OIL (1 Qt.)

Engine builders have grown increasingly concerned that many modern motor oils do not provide adequate wear protection for new engines particularly those using flat-tappet cams. The Royal Purple Break-in Oil is formulated to allow optimal ring seal and protect rotating assembly components such as the camshaft and valve train from initial start up wear. The Break-in Oil combines highly refined mineral oil preferred for engine break-in with advanced additives containing high levels of zinc and phosphorus to optimize protection in flat-tappet and roller engines. The Royal Purple Break-in Oil is fully formulated and does not require the use of any other chemical additives. Recommended: Use the Royal Purple Motor Oils after the engine is broken in for maximum engine performance. SHIPPING: This product cannot be shipped 2nd-Day Air
