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. 1500 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. APPLICATION HPR 50 is designed for use in 4, 6 & 8+ cylinder naturally aspirated, supercharged and turbocharged petrol engines. It is 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. APPLICATION 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 VEHICLE AND FUEL TYPES 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. EXTRA TEN TECHNOLOGY 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.
