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. Royal Purple has addressed this issue by developing a new engine break-in oil that promotes a gentle start-up and gives you superior protection from rough-running engine problems.
Royal Purple 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.
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. Its high film strength provides engine protection superior to full synthetic oils that are not engineered specifically for new engines. Perfect for your new factory-ordered vehicle and engine rebuilds, Royal Purple Break-In Oil is fully formulated and does not require the use of any other chemical additives. After the engine is broken in, we recommend using the right Royal Purple high performance synthetic engine oil for your vehicle.
