Royal Purple produces a wide range of high performance lubricants for nearly every consumer and industrial application. Royal Purple’s founder John Williams was a pioneer in the development of high performance synthetic lubricants and collectively, Royal Purple’s formulators have more than 200 years of expertise in developing high performance lubricants. Royal Purple focuses exclusively on developing state-of-the-art lubricants. Unlike companies that primarily focus on fuel and other petroleum byproducts, Royal Purple’s sole mission is to develop products that significantly outperform other synthetic and mineral based oils.

ENGINE BREAK-IN OIL
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® Break-In Oil.
