Provides outstanding engine performances in the most severe driving conditions. Very high performance cars powered by gasoline or diesel, naturally aspirated or turbocharged multi-valve injection engines. Tuned engines operating on a wide range of engine speeds and temperatures, in the most severe driving conditions. Engines producing medium dilution into the oil. Ester based formula to ensure outstanding oil film resistance at very high temperature for maximum horsepower, torque output and wear protection. Very high API (American Petroleum Institute) performance level for improved oxidation resistance and deposit protection, better wear protection and low-temperature performance over the life of the oil. Perfect compatibility with the latest generations of engines requiring lubricant with API SM specification. The viscosity grade 5W-40 allows excellent oil flow into the engine oil circuit, faster oil pressure set-up and engine revs rising.
