Royal Purple 11903 HMX SAE 0W-20 High-Mileage Full Synthetic Motor Oil 5 Qt

Royal Purple HMX SAE 0W-20 is a full synthetic high-mileage motor oil engineered specifically for four-cycle gasoline engines with 75,000 miles (120,000 km) or more. Formulated with Royal Purple's proprietary Synerlec® additive technology and robust zinc/phosphorus anti-wear additives, HMX works to minimize wear and restore lost engine performance in aging powerplants.

HMX goes beyond standard motor oil by incorporating seal conditioners that revitalize hardened gaskets and seals, helping reduce the oil consumption that commonly develops in higher-mileage engines. Stout detergents aggressively clean existing engine deposits and maintain internal cleanliness for superior corrosion protection and long-term engine longevity.

Key Features:

• Proprietary Synerlec® technology delivers exceptional film strength to reduce friction and protect engine components
• Ionic attraction to metal surfaces maintains a protective oil film during cold starts, minimizing start-up wear
• Chemically enhanced seal conditioners revitalize hardened seals and reduce oil consumption
• Heavy-duty detergent package removes power-robbing deposits and prevents new build-up
• Outstanding oxidation resistance supports extended oil drain intervals up to 15,000 miles or one year
• Meets Chrysler FCA US MS-6395, Ford WSS-M2C962-A1, and GM dexos™1 Gen 3 warranty requirements
• Meets API Service SP performance requirements for gasoline engines
