RAVENOL 10W-40 is a high additive treated engine oil that allows an energy-saving operation because of its additivation, choice of base oils, and viscosity adjustment. In order to guarantee the low viscosity of the SAE class 10W as well as a low evaporation loss RAVENOL, TSi SAE 10W-40 is produced on the basis of hydro crack oils and polyalphaolefins (PAO) which correspond to the high tech demands. RAVENOL TSi SAE 10W-40 contains less than 30 % Polyalphaolefins (PAO).
