CHEVRON MOTOR OIL API SG / CD SAE 20W-50

Quality engine oil for use in a wide range of older passenger car and lightduty commercial vehicle gasoline engines where API SG or lower performance lubricants are required and SAE 20W-50 viscosity is acceptable. Proven metallo-organic anti-wear additive system resists wear under all operating conditions by forming a protective layer on contact surfaces. Multigrade viscosity provides additional protection against wear at start-up and under high temperature operating conditions. Metallic detergent and ashless dispersant additive system preserves power and performance by providing good control of piston and ring deposits. Good thermal and oxidation stability resists in-service oil degradation that contributes to filter blocking and sludge formation.
