HMX®

Royal Purple® HMX® is specifically formulated with robust zinc / phosphorus anti-wear additives and Royal Purple’s proprietary additive technology Synerlec® to minimize wear and restore lost engine performance.

HMX is chemically enhanced to revitalize hardened seals reducing oil consumption common in higher mileage engines. Stout detergents remove engine deposits and maintain cleanliness promoting engine longevity.

Royal Purple’s advanced Synerlec technology provides an exceptional film strength by reducing friction for peak engine performance. Synerlec also provides outstanding oxidation resistance to safely extend oil drains, and an ionic attraction to metal components maintaining a film of oil on parts minimizing start-up wear.
