A synthetic multigrade oil with ester content for modern, highly stressed high-speed diesel engines, with and without turbocharging, operating under severe conditions. Product Features: - The highest quality synthetic base and ideal viscosity across a broad temperature range offer unparalleled protection against friction, wear, and scuffing, significantly extending the machine's life in all – even extreme – operating conditions and reducing fuel consumption considerably. - The stable synthetic base, combined with natural antioxidants, increases the oil's thermal oxidation resistance. Combined with excellent detergent and dispersant properties (TBN >12.5) and low ash content, reduces residue and varnish formation efficiently, prevents deposits of any kind, and keeps engine parts, especially the cylinder-piston group, ideally clean throughout the entire oil change interval. - A unique formulation gives the oil aging resistance; reduced evaporation capability and an increased flash point reduce oil loss during coking. This makes it usable both in engines with extended oil change intervals (Longlife service of no less than 500 operating hours) and in conventional engines. - Due to its synthetic base with optimum viscosity, it exhibits excellent cold behavior and a low pour point. This ensures good oil flowability, easy turning of engine components at low temperatures, trouble-free cold start (down to -30°C), and reduced start wear. - Compatible with engines with exhaust gas recirculation and SCR, not suitable for engines with diesel particulate filters (DPF). - Efficiently protects engine parts from any type of corrosion. - Has reduced foam formation. - Efficiently resists shear force increase during operation caused by increased viscosity due to soot distribution. - Can also be used with fuel with increased sulfur content. Designed for any highly stressed diesel engines of road (tractors, buses), off-road (construction, mining and agricultural machinery) and specialized vehicles from manufacturers in Europe, America, and Asia, meeting Euro I, II, III, IV, V requirements with required engine oil quality level CI-4 or lower. Can also be used in gasoline engines with required engine oil quality level API SL or lower.
