Chevron Supreme Motor Oil is a premium conventional mineral motor oil formulated with quality base oils and a robust additive package including shear-stable viscosity index improvers, detergents, dispersants, anti-wear agents, corrosion inhibitors, antioxidants, and anti-foam additives. The SAE 20W-50 viscosity grade delivers outstanding protection against harmful deposits, sludge, and contamination in automotive engine applications.

This case contains 12 individual 1-quart (946 ml) bottles, providing a total of 11.35 liters of motor oil. The 20W-50 grade is specifically designed for older and high-mileage vehicles, high-performance and high-RPM engines, and vehicles subjected to demanding conditions such as highway trailer towing, sustained uphill driving, and racing or rally use. The high dispersancy level prevents deposit and sludge formation under both normal and stop-and-go driving, while superior high-temperature oxidation stability prevents viscosity increase and oil gelation in the crankcase, keeping the PCV system clean and engine performance smooth.

Certified to API SQ, Chevron Supreme 20W-50 is suitable for gasoline engines specifying legacy API specifications including SN Plus, SN, SL, SJ, SG, and SF. It is also compatible with four-stroke engines used in lawnmowers, forestry equipment, construction machinery, and snow blowers. Key technical data: kinematic viscosity 165.5 mm²/s at 40°C and 18.5 mm²/s at 100°C, viscosity index 126, flash point 248°C (478°F). Product manufactured in the USA.
