CLASSIC LIGHT is a premium mineral, SAE 20W-60 CAN BE USED WHERE THE FOLLOWING SAE VISCOSITY IS RECOMMENDED SAE 30 20W-50 25W-60 CLASSIC LIGHT is suitable for passenger cars, motorcycles, 4WD's, light & heavy duty commercial vehicles (trucks, buses & heavy equipment), tractors & industrial machines that originally specified a multigrade 20W-40, 20W-50 or monograde SAE 30 engine oil and were fitted with an engine oil filter. CLASSIC LIGHT is a multi-grade oil that contains a special additive pack that suit vehicles of the era and is compatible with grades that were originally specified. This oil exceeds the specification requirements of original oils required during this period hence offering a greater level of engine protection compared to original oils. It is ideal in vehicles operating in cooler ambient temperatures and is suitable as an engine/transmission oil in vehicles manufactured by Austin, Morris, BMC & Leyland. It is also suitable for use in motorcycles that require this viscosity and grade of oil. CLASSIC LIGHT is an API SG/CD grade oil and contains HIGH ZINC levels for added anti-wear protection for older engines. CLASSIC LIGHT features a standard multigrade cold temperature SAE viscosity grade with an increased operating temperature range that provides and added layer of protection for the engine especially under increased load and temperature conditions. Multigrade oils provide better start up protection and better protection at operating temperature than monograde oils and they do not need to be changed in winter and summer.
