HPR 50 is a premium high performance mineral, 40-70, non-friction modified engine oil. It features a DOUBLE LAYER of engine wear protection with FULL ZINC (approx. 1400+ ppm levels) and Penrites advanced EXTRA TEN technology. Protects against corrosion, oil oxidation and sludge under all operating conditions.

HPR 50 is recommended for use in vehicles where SAE 20W-50, 25W-50 and 25W-60 multigrade or where SAE 50 monograde engine oils were originally recommended by the manufacturer.


HPR 50 is designed for use in 4, 6 & 8+ cylinder naturally aspirated, supercharged and turbocharged petrol engines. It is particularly suited for use under high load conditions such as towing and competition or where ambient temperatures are high.

It can be used where API SL and previous SJ (1995-2000), SH (1992-1995), SG (19891992) or earlier specifications are recommended. It is suitable for use in engines showing signs of excessive oil consumption and can be used to provide protection for older and worn engines that require a heavier viscosity engine oil to maintain oil pressure.

HPR 50 has been proven for years in race and competition conditions where it has an unequalled reputation for protection in engines requiring a high performance mineral oil. It is the product of choice for many competitors running competition vehicles in circuit & drag racing, rallying, drifting, hill climb, targa events, time trials and regularity


HPR 50 is suitable for passenger cars, 4WD's, light and heavy duty commercial vehicles, motorcycles, industrial and agricultural machinery. It is compatible with petrol & E10 for on road use & racing fuels such as Methanol, Nitro, Avgas, Alcohol & E85 for competition use.


HPR 50 features the Penrite EXTRA TEN in the oil's SAE rating. This technology helps protect your engine by using a normal start up viscosity with an oil that has a higher operating temperature viscosity. This improves engine oil film strength, lowering frictional heat whilst providing an extra layer of anti wear protection over standard SAE grade oils, reducing engine wear in all driving conditions.


HPR 50 is a full zinc formulation engine oil for greater protection of cam shafts, lifters and other internal engine parts from wear. No further zinc or other additive is needed with this product.


NOTE: when changing oil, Penrite recommend using Penrite Engine Flush, a fast acting, solvent free, engine cleaning formulation that removes engine deposits, sludge and contaminants with the oil service drain. It contains added zinc for engine wear protection and its fast acting formulation works in 10 minutes.
