A synthetic multigrade oil for high-speed, highly stressed diesel engines with and without turbocharging operating in severe conditions. The motor oil has successfully passed the road and laboratory tests at VOLVO, MACK and RENAULT test centers and received their written approvals. Product Properties: - An innovative additive package combined with a high-quality synthetic base and optimal viscosity over a wide temperature range provides excellent protection against friction, wear, and scuffing, significantly extending the machine's life in all – even extreme – operating conditions and reducing fuel consumption; - Phenolic and amine antioxidants combined with a synthetic base give the oil increased thermal oxidation resistance, which, in conjunction with excellent detergent and dispersant properties and low ash content, efficiently reduces deposits and varnish formation, prevents deposits of any kind, and keeps engine parts, especially the cylinder-piston group, ideally clean throughout the entire oil change interval; - A unique synthetic composition ensures excellent aging resistance, while reduced volatility and increased flash point reduce oil loss from coking. Thus, it is usable in engines with extended oil change intervals (Longlife-Service) as well as in regular engines; - Due to the synthetic base and optimal viscosity, it boasts excellent low-temperature performance and low pour point. This ensures good oil pumpability, smooth operation of engine components at low temperatures, trouble-free cold start (down to -30 ºC), and reduction of start-up wear; - Compatible with all exhaust gas neutralization systems; Diesel Particulate Filter (DPF), Three-Way Catalyst (TWC), Exhaust Gas Recirculation (EGR) and Selective Catalytic Reduction (SCR) due to Low SAPS technology; - Efficiently protects engine parts from any kind of corrosion; - Reduced foam formation; - Efficiently withstands shear force increase during operation, caused by increase in viscosity due to soot dispersion; - Suitable for engines powered by liquefied natural gas (LNG) or liquefied petroleum gas (LPG). Suitable for any highly stressed diesel engines of road (trucks, buses), off-road (construction, mining, and agricultural machinery) and special vehicles from manufacturers in Europe, America and Asia, meeting the requirements of Euro I–V with the required oil quality level CK-4 or lower. Can also be used in gasoline engines with the required oil quality level API SN or lower.
