Description

The Maxima Racing Oils RS is a premium 10W-40 full synthetic engine oil engineered to meet the demands of race-grade performance. Its foundation is a 100% synthetic triple ester blend, providing a robust base for an industry-leading additive system focused on maximizing engine performance and protection. This technologically advanced formula incorporates specialized anti-wear and extreme pressure additives. These components are crucial for shielding vital engine parts from the intense stresses and extreme temperatures encountered in high-performance racing applications. Furthermore, its regenerative, high viscosity index synthetic polymer system ensures the oil maintains its integrity, resisting mechanical breakdown and viscosity loss even under severe operating conditions. The benefits of using Maxima RS oil extend to tangible improvements in engine output and longevity. Users can expect increased horsepower and torque, alongside enhanced engine cleanliness. It actively reduces wear on critical components such as bearings, cams, and lifters, ultimately contributing to an extended engine lifespan. The oil's formulation is specifically engineered with a high Zinc/Phosphorous content, making it ideal for engines utilizing both flat tappet and roller element designs.
