HD Oil is a premium, heavy duty, high performance mineral, 50-70, non friction modified, 4 stroke engine oil. It contains a superior anti wear package of HIGH ZINC (exceeding 1750+ ppm levels) for ultimate engine, gearbox & clutch protection and a multi-grade viscosity designed to maintain oil pressure and consumption control for older and classic motorcycles.
HD Oil is primarily recommended for use in classic motorcycles where SAE 50 & SAE 60 monograde oils were specified. It is also equally suitable for use in transmissions with wet clutch systems where engine & gearbox oils are combined. It has optimum clutch slip prevention in these systems.
HD Oil is particularly suited to be used in pre-Evolution (1984) engined Harley Davidson motor cycles. Specific models such as -
HD Oil is also suitable for other large V-Twin bikes such as Ducati, Hummel, Indian, NSU, PUCH, Henderson & early Buell. It is also ideal oil for Classic British motorcycles such as Norton, AJS & BSA including single cylinder 350 to 500cc low revving engines and 500 to 650 cc Parallel twins.
