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 TYPE OF USE: Very high performance cars powered by diesel or gasoline, naturally aspirated or turbocharged multi-valve injection engines. Engines tuned operating in a wide range of rpm and temperatures, in the most severe driving conditions. Engines producing medium to high dilution in 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, improved deposit protection, better wear protection, and better low-temperature performance over the life of the oil. Perfect compatibility with the latest generations of engines requiring a lubricant with the specification API SM / CF.; 5W-50 grade allows excellent oil flow into the engine, faster oil pressure set up and faster revs rising. ;RECOMMENDATIONS: Oil change: according to your own use, or tuners recommendations. Can be mixed with synthetic or mineral lubricants.
