HPR 15 is a premium, full synthetic SAE 15W-60 engine oil. It features a DOUBLE LAYER of engine wear protection with FULL ZINC and Penrites advanced EXTRA TEN technology. It uses a combination of advanced additive technology and a low shear rate viscosity modifier, to ensure additional protection against wear, corrosion, oil oxidation, piston deposits and sludge under tough conditions. HPR 15 is recommended for use in vehicles where SAE 15W-50 or 20W-50 engine oils were originally recommended by the manufacturer. APPLICATION HPR 15 is designed for use in modern 4, 6 & 8+ cylinder multi-cam, multi-valve (including VVT), naturally aspirated, supercharged & turbocharged engines. It is not suitable for use in Rotary 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 ACEA A3/B3 or A3/B4 is recommended in model years prior to 2017 and also where API SN and previous specifications SM (2004-10), SL (2001-04), SJ (1998-2000) or earlier specifications are recommended. It is suitable for use in many Diesel and LPG powered vehicles requiring an engine oil meeting API CF or older specifications. It is not recommended for use in diesel vehicles fitted with a DPF (Diesel Particulate Filter). VEHICLES AND FUEL TYPES HPR 15 is suitable for use in passenger cars, competition & high performance vehicles, 4WDs and light commercial vehicles and is compatible with Petrol, LPG (Dual Fuel), E10, E85 (competition), Diesel (Non- DPF) and other conventional and racing fuels. If using with E85, Penrite recommend more frequent service intervals. It is not recommended for use in motorcycles. EXTRA TEN TECHNOLOGY HPR 15 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. IMPORTANT INFORMATION WHEN CHANGING OIL. 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.
