Classic MEDIUM is a Premium Mineral, 25W-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 40 Monograde oil was specified by the manufacturer. It controls Oil Consumption and maintains oil pressure in older engines.
Classic MEDIUM 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 40, Monograde engine oil and were fitted with an engine oil filter.
Classic MEDIUM 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 moderate ambient temperatures or as a Summer Grade oil if using Classic LIGHT engine oil as a Winter grade or if the engine is suffering from excessive Oil Consumption.
Classic MEDIUM 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 MEDIUM 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.
