HPR Diesel 15 is a premium high performance semi synthetic SAE 15W-50, non-friction modified engine oil. It features a DOUBLE LAYER of engine wear protection with FULL ZINC and Penrites advanced EXTRA TEN technology. It contains a combination of high technology additives, including increased dispersant levels and low shear viscosity modifiers. It protects against corrosion, oil oxidation and sludge under all operating conditions.


HPR Diesel 15 is designed for use in modern 4, 6 & 8+ cylinder multi cam, multi valve (Including VVT), naturally aspirated, supercharged, turbocharged common rail and direct injection engines.

HPR Diesel 15 is recommended for use in vehicles where SAE 15W-40, SAE 15W-50 or SAE 20W-40 grade engine oils were originally recommended by the manufacturer. It can be used where API CI-4, Global DLD-1, DLD-3, DHD-1 or JASO DH-1 are specified in the owners hand book. It can also be used where ACEA A3/B3, ACEA A3/B4 or ACEA E7 is recommended in model years prior to 2017. It is suitable for use in many older diesel and LPG powered vehicles requiring an engine oil meeting API CH-4, CG-4, CF-4 or older specifications.

HPR Diesel 15 is NOT recommended for use in diesels fitted with a DPF (Diesel Particulate Filter) that require an ACEA C grade Low-Mid SAPS (Sulphated Ash, Phosphorus & Sulphur) engine oil. We recommend checking the recommendation guide for the correct grade and specification.


HPR Diesel 15 features Penrites Extra Ten Technology in the oils operating temperature viscosity that provides better wear protection, oil pressure and reduced oil consumption at operating temperature. It provides an added layer of protection for engines that are under high load conditions, competition, operating in high ambient temperatures or showing signs of excessive oil consumption.


HPR Diesel 15 is suitable for use in diesel engines in passenger cars, motorcycles, 4WDs, light & heavy duty commercial engines in trucks, tractors, agricultural & earthmoving equipment as well as industrial equipment such as fork lifts & stationary engines. It can be used with Diesel & Petrol/E10/LPG (Dual Fuel). Suitable for petrol and LPG engines as a mixed fleet oil and can be used in motorcycles with wet clutches.


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.
