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.
