Fully Synthetic Ester based lubricant, specially designed for high performance tuined turbo-charged, supercharged gasoline and diesel multi-valve fuel injection engines. Provides outstanding engine performances in the most severe driving conditions. API Standards: API SM/CF TYPE OF USE: 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. ;PERFORMANCES: Ester Technology: Ester based formula to ensure outstanding oil film resistance at very high temperature for maximum horsepower, torque output and wear protection. Oil pressure is stable whatever the conditions of use.; 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. ;RECOMMENDATIONS: Oil change: according to your own use, or tuners recommendations. Can be mixed with synthetic or mineral lubricants.
