HP No. 1 is a high-performance, super-premium diesel engine oil developed using advanced additive chemistry and top-quality paraffinic base oils. It has been specially designed to meet the demands of new-generation emission-compliant diesel engines equipped with Exhaust Gas Recirculation (EGR) systems. This modern formulation provides long-lasting protection against wear, corrosion, and deposit formation, ensuring smooth performance and extended engine life even under the most demanding operating conditions. The oil delivers outstanding thermal and oxidative stability, which prevents the oil from breaking down under high temperatures and severe loads. This ensures that the lubricant maintains its viscosity and protective film strength throughout its service life. By minimizing sludge formation, piston deposits, and varnish buildup, HP No. 1 keeps the engine’s internal components exceptionally clean, leading to improved reliability and reduced maintenance costs. It also demonstrates excellent dispersancy and detergent properties, allowing it to handle high soot levels effectively and maintain consistent lubrication in modern diesel engines. HP No. 1 enhances the longevity of crucial engine parts such as cylinder liners, pistons, valves, and rings, reducing wear and improving sealing efficiency. Its optimized viscosity balance provides superior lubrication in both cold and hot conditions, ensuring smooth starts, steady oil flow, and stable pressure in all types of operating environments. The oil’s superior shear stability prevents viscosity loss over extended drain intervals, contributing to longer oil life and greater cost-efficiency for vehicle operators. In addition to its strong protective and performance-enhancing characteristics, HP No. 1 also plays an important role in reducing emissions and promoting environmental cleanliness. The low volatility and clean-burning nature of this oil help minimize exhaust smoke and contribute to better fuel economy. It is ideally suited for use in heavy commercial vehicles, multi-utility vehicles, and smaller diesel-powered passenger cars that require a robust lubricant capable of handling high thermal loads and emission control systems. HP No. 1 meets and exceeds the performance standards of several global specifications, including API CI-4, ACEA A3/B4/E7, MB 228.3, Volvo VDS-3, MAN 3275, CES 20071/72/76/77/78, Global DHD-1, and JASO DH-1. Its blend of high-quality base stocks and advanced additive technology ensures maximum protection, outstanding performance, and long engine life across a wide range of diesel engines.
