Description

Maxima's RS520 is a high-performance, full-synthetic, triple ester racing engine oil is engineered for peak performance while providing ultimate protection under the most severe conditions. The extensively developed formulation combines unique esters and proprietary friction-reducing additives with advanced anti-wear and extreme pressure agents to ensure optimal power output and wear resistance. Regenerative, shear-stable polymers maintain viscosity and film thickness, preserving the power and longevity needed to beat the competition. This 5-gallon pail uses a triple ester racing formula for ultimate protection and peak performance. The proprietary additive system and esters work together to fight oxidation and wear. Its surface-active chemistry clings to engine surfaces, helping to keep them clean. It also includes advanced anti-wear and extreme pressure additives that are particularly helpful for engines with flat tappet cams, enabling maximum torque and power output.
