Driving an older vehicle? Does it have at least 75,000 miles on it? HMX is synthetic motor oil specifically designed by Royal Purple engineers to minimize wear inside older engines and restore lost engine performance. Chemically enhanced to revitalize hardened seals, HMX is especially effective at reducing oil consumption common in higher mileage engines with stout detergents that remove deposits and build-up. These detergents then maintain that cleanliness for superior corrosion protection and engine longevity. Royal Purple HMX is formulated with robust zinc/phosphorus anti-wear additives and Royal Purple's proprietary additive technology Synerlec® to provide unsurpassed film strength. HMX also provides outstanding oxidation resistance to safely extend oil drains. Engineered by the brightest minds in additive technology, HMX creates a molecular ionic attraction to metal components, which helps maintain a film of oil to minimize wear and tear upon start-up. HMX HIGH MILEAGE SYNTHETIC MOTOR OIL ADVANTAGES Minimizes wear and restores lost engine performance Extends drain intervals Exceptional oxidation stability Reduces engine deposits Superior corrosion protection Fortified with zinc/phosphorus anti-wear additive 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 4-cycle gasoline engine with 75,000 miles (120,000 km) or more.
