Maxima RS1040 Full Synthetic 10W-40 Racing Engine Oil – 1 Quart

Maximize power output and protect your engine under the most severe racing conditions with Maxima RS1040 Full Synthetic Racing Engine Oil. A high-performance, triple ester full-synthetic formulation engineered for peak performance and ultimate protection, RS1040 combines unique esters and proprietary friction-reducing additives with advanced anti-wear and extreme pressure agents — ensuring optimal power output and wear resistance from the first lap to the last.

Regenerative, shear-stable polymers maintain viscosity and film thickness throughout the oil’s service life, preserving the power and engine longevity needed to beat the competition.

Key Features

• Triple Ester Full Synthetic Formulation: Unique ester blend provides superior film strength, lubricity, and thermal stability compared to conventional or single-ester synthetics
