Royal Purple HMX 10W30 Fully Synthetic Performance Engine Oil
Royal Purple HMX 10W30 Fully Synthetic Performance Engine Oil
Royal Purple HMX Fully Synthetic Performance Engine Oil 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.
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.
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. These detergents then maintain that cleanliness for superior corrosion protection and engine longevity.
Meets API Service SL warranty requirements for petroleum engines. API recommends SL oils for 2004 or older automobiles. Royal Purple recommends this product for any four-cylinder petroleum engine with 75,000 miles (120,000 km) or more.
