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. HMX 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.

Performance Advantages:
  • Minimizes wear and restores lost engine performance
  • Fortified with zinc/phosphorus anti-wear additive
  • Extended drain intervals
  • Exceptional oxidation stability
  • Reduces engine deposits
  • Superior corrosion protection

    Please Note: Royal Purple meets API Service SL warranty requirements for gasoline engines. API recommends SL oils for 2004 or older automobiles. Royal Purple recommends this product for any four-cycle gasoline engine with 75,000 miles (120,000 km) or more.
