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.

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.
