Royal Purple HMX SAE 5W-30 High-Mileage Synthetic Motor Oil is specifically designed to minimize wear and restore lost performance in engines with more than 75,000 miles. This premium formula combines robust zinc/phosphorus anti-wear additives with Royal Purple's proprietary Synerlec additive technology to deliver exceptional protection and performance recovery for higher-mileage vehicles.

Key Features:

• Chemically enhanced to revitalize hardened seals, reducing oil consumption common in high-mileage engines
