Maxima Racing Oils RS520 Full Synthetic 5W-20 Engine Oil – 1 Quart

Manufacturer Part Number: 39-04901

Maxima RS520 is a race-grade, full-synthetic 5W-20 engine oil developed for high-performance racing, street/strip and competition engines requiring a lower-viscosity lubricant. Its advanced triple-ester formulation provides exceptional film strength, thermal stability and wear protection under extreme engine loads and elevated operating temperatures.

RS520 combines friction-reducing chemistry with advanced anti-wear and extreme-pressure additives to protect bearings, camshafts, lifters, crankshafts and other critical engine components. The lower 5W-20 viscosity helps reduce internal friction and parasitic drag while maintaining the protective oil film required by high-output engines.

Its shear-stable polymer system resists viscosity loss during sustained high-RPM operation. The high-zinc and phosphorus formulation provides additional anti-wear protection for both flat-tappet and roller-cam engines. RS520 is fully formulated and does not require supplemental zinc additives or oil boosters.
