20W50 Synthetic Blend 1 Quart

The 20W50 Synthetic Blend 1 Quart from Extreme Racing Oil is designed for high-performance engines that require exceptional protection under extreme conditions. This motor oil is ideal for vintage, modified, and racing applications, particularly in flat-tappet cam engines, big-block V8s, and turbocharged engines that operate at high RPMs. Whether you're rebuilding a classic muscle car or maintaining a competition vehicle, this synthetic blend is engineered to meet your needs.

With a viscosity rating of 20W50, this oil flows like a 20-weight oil during startup, ensuring rapid lubrication of critical components before full oil pressure is achieved. It maintains a 50-weight film strength at operating temperatures, providing robust protection. The synthetic blend technology combines mineral and synthetic base stocks, enhancing oxidation stability and reducing sludge formation, which leads to extended oil change intervals compared to conventional oils.

This motor oil is particularly beneficial for engines with high-lift cam profiles or solid roller tappets, as it contains enhanced anti-wear additives like zinc and phosphorus. These additives protect vital engine components from accelerated wear, ensuring longevity and performance. The 1-quart container size is perfect for top-offs between oil changes or for those who prefer to keep multiple grades on hand for different driving conditions.
