An energy-saving synthetic (PAO-based) engine oil for high-load high-speed diesel engines of the latest generation, with or without turbocharging, for severe operating conditions. Product Features: - A unique low-viscosity synthetic PAO-containing base of the highest quality with ideal viscosity in the required temperature range combined with an innovative additive package provides unrivaled protection against friction, wear, and scuffing, significantly prolonging machine life in all – even extreme – operating conditions over a broader temperature range and significantly reduces fuel consumption; - A synthetic PAO-containing base and an innovative additive package grant the oil increased thermal oxidation stability and excellent detergent and dispersant properties (TBN>12.5), efficiently reducing residue and varnish formation, preventing deposits of any kind, and keeping engine parts, especially the cylinder-piston group, ideally clean throughout the entire oil change interval; - A unique PAO-containing composition ensures oil aging resistance, reduced volatility, and higher flash point reduce oil loss during coking, making it usable both in engines with extended oil change intervals (Longlife service up to 90,000 km) and in ordinary engines; - Due to its PAO-containing base, it has the best cold-weather performance and low pour point. This ensures good oil flow, easy rotation of engine components at low temperatures, trouble-free cold start (down to -35 °C), and reduction of start-up wear; - Efficiently protects engine parts from corrosion of any kind; - Effectively resists the increase in shear force during operation caused by the rise in viscosity due to soot dispersion; - Can also be used with fuel having increased sulfur content. Intended for any high-load diesel engines of road (trucks, buses), off-road (construction, mining, and agricultural machinery), and special vehicles from manufacturers in Europe, America, and Asia, meeting Euro I–V requirements with the required motor oil quality level ACEA E4, E7, or lower.
