Chevron Supreme Motor Oils are premium quality automotive engine oils.

Chevron Supreme Motor Oils SAE 5W-20, 5W-30, 10W-30, 10W-40, and 20W-50 are formulated with ISO-SYN™ base stocks, a shear-stable viscosity index improver, and contain detergent, dispersant, wear control, antioxidant, corrosion inhibitor, and foam suppressant additives.

The high viscosity index of Chevron Supreme Motor Oils ensures low viscosities at low temperatures for easy cold starting and rapid warm-up and high viscosities at high temperatures for fuel economy, oil economy, and effective protective films for engine parts.

Their antiwear additive provide excellent wear protection of critical engine parts.

A high level of dispersancy in Chevron Supreme Motor Oils protects against deposit and sludge formation in stop-and-go driving and sustained high temperature operation, and protects against corrosion.

Their excellent high temperature oxidation stability prevents viscosity increase and oil gelling in the crankcase. They keep PCV systems clean to maintain smooth engine performance.

Applications

Chevron Supreme Motor Oils are recommended for all four-stroke gasoline engines used in passenger cars, light trucks, power boats, motorcycles, and other mobile and stationary equipment. They are excellent for high revving engines in small cars and light trucks. All grades are specially formulated for using in turbocharged engines.

SAE 10W-40 is still a very popular viscosity grade in warmer climates, though it is not recommended by most auto manufacturers for their late model North American vehicles. It is often recommended for older model cars that see regular high temperature operation.
