OIL, Penrite, Shelsley 40W70 Heavy, 5L

SHELSLEY HEAVY is a premium mineral, 40-70, high zinc, very low detergent engineoil designed specifically for petrol, kerosene and diesel fuelled vintage, pre-war and postwar vehicles manufactured to 1950. It features a double layer of engine wear protectionwith high zinc and increased operating temperature viscosity over monograde oils.

APPLICATIONSHELSLEY HEAVY is suitable for passenger cars, motorcycles, 4WD's, light & heavyduty commercial vehicles (trucks, buses & heavy equipment), tractors & industrialmachines that originally specified a SAE 50 monograde grade engine oil fitted with/without an engine oil filter. Those vehicles that require a higher detergency should usePenrite Classic Heavy Engine Oil.SHELSLEY HEAVY is a 40-70 engine oil for vehicles that specified SAE 50 gradeengine oils. It is recommended for use in large engined vehicles operating in high ambient temperatures, or invehicles with oil consumption problems. Ideal in large capacity sleeve valve engines fitted to such makes asMinerva, Mors, Knight and Daimler.SHELSLEY HEAVY is ideal for use in early vintage (pre 1950) motorcycles, incorporating sight glasses, pilgrim oilpumps and total loss lubrication systems. It is suitable for use in motorcycles fitted with a wet clutch.SHELSLEY HEAVY contains a special additive pack that suits vintage vehicles of the era and is compatible withgrades that were originally specified. This oil exceeds the specification requirements of the original oils requiredduring this period hence offering a greater level of engine protection compared to original oils.SHELSLEY HEAVY features a standard multigrade cold temperature SAE viscosity grade with an increasedoperating temperature range that provides and added layer of protection for the engine especially under increasedload and temperature conditions. Multigrade oils provide better start up protection and better protection at operatingtemperature than monograde oils and they do not need to be changed in winter and summer as they used to do.SHELSLEY HEAVY is an API SC/CC grade oil that features very low detergent levels and contains HIGH ZINClevels for added anti-wear protection for older engines.SHELSLEY HEAVY contains a "Tacky Additive" so that when vehicles are laid up, the engine oil doesn't run off theinternal surfaces. This combined with an increased level of rust inhibitor, provides protection against corrosion anddeterioration when the engine is not used or in storage.NOTE: when changing oil, Penrite recommend usingPenrite Engine Flush, a fast acting, solvent free, enginecleaning formulation that removes engine deposits, sludge and contaminants with the oil service drain. It containsadded zinc for engine wear protection and its fast acting formulation works in 10 minutes.
