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.
