CLASSIC HEAVY is a premium mineral, 40-70, high zinc, low detergent engine oil designed specifically for petrol and diesel fuelled vehicles manufactured between 1950 and 1989. It features a double layer of engine wear protection with high zinc and increased operating temperature viscosity over older style multigrade oils or where SAE 50 monograde oil was specified by the manufacturer. It controls oil consumption and maintains oil pressure in older engines.
CLASSIC HEAVY is suitable for passenger cars, motorcycles, 4WD's, light & heavy duty commercial vehicles (trucks, buses & heavy equipment), tractors & industrial machines that originally specified a SAE 50, monograde engine oil and were fitted with an engine oil filter. CLASSIC HEAVY 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 for older vehicles operating in high ambient temperatures or as a summer grade oil for vehicles that require SAE 40 grade oils. It is also suitable for large engined vehicles that are suffering from excessive oil consumption. CLASSIC HEAVY is an API SG/CD grade oil and contains HIGH ZINC levels for added anti-wear protection for older engines. CLASSIC HEAVY 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 as they used to do. CLASSIC HEAVY contains a "Tacky Additive" so that when the vehicles are laid up, the engine oil doesn't run off the internal surfaces. This combined with an increased level of rust inhibitor, provides protection against corrosion and deterioration when the engine is not used or in storage. CLASSIC HEAVY is suitable for use in motor cycles fitted with a wet clutch.
