Royal Purple HMX high-mileage motor oil is specially formulated with robust zinc/phosphorous anti-wear additives and proprietary Synerlec technology to minimize aging and restore lost engine performance.

Stout detergents remove engine deposits and maintain cleanliness to promote engine longevity. Royal Purple's advanced Synerlec technology provides exceptional film strength, which lessens friction for peak engine performance.
