An energy-saving synthetic (PAO-based) motor oil for high-performance diesel engines of the latest generation with high speeds, with or without turbocharging, for heavy duty 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 unparalleled protection against friction, wear, and scuffing, significantly extending the machine's life in all – even extreme – operating conditions over a wider ambient temperature range and significantly reducing fuel consumption; - A synthetic PAO-containing base and an innovative additive package give the oil increased thermal oxidation resistance 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 the oil's aging resistance, reduced evaporation capability, and increased flash point reduce oil loss through carbonization. This makes it usable in engines with extended oil change intervals (long-life service up to 90,000 km) as well as in regular engines; - Due to its PAO-containing base, it has excellent cold behavior and low pour point. This ensures good oil pumpability, easy engine component rotation at low temperatures, trouble-free cold start (down to -35 ºC), and reduction of start-up wear; - Efficiently protects engine parts against corrosion of any kind; - Efficiently resists the increase in shear force during operation caused by the increase in viscosity due to soot distribution; - Can also be used when using fuel with increased sulfur content. Intended for any high-performance diesel engines of road (trucks, buses), off-road (construction, mining, and agricultural machinery) and special vehicles from manufacturers in Europe, America, and Asia that meet the requirements of Euro I–V with the required oil quality level ACEA E4, E7 or lower.
