Premium 10w30 Break-in Oil, 6 quarts, 1 Pack

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. To address this issue, Royal Purple has developed a new engine break-in oil that promotes a gentle start-up and delivers superior protection from rough-running engine problems.

Formulated to allow optimal ring seal and protect rotating assembly components such as the camshaft and valve train from initial start-up wear, this engine break-in oil boasts a high film strength that provides engine protection superior to full synthetic oils not specifically engineered for new engines.

Ideal for your new factory-ordered vehicle and engine rebuilds, this fully formulated oil does not require the use of any other chemical additives. Featuring advanced additives with high levels of zinc and phosphorus, it is designed to optimize protection in both flat-tappet and roller engines.
