German Gold Engine Power 10W-40 is a high performance semi-synthetic low friction oil to be used in passenger cars gasoline and diesel engines. It is produced by blending high quality synthetic oils and mineral base stocks and additives of most progressive technology. Suitable also under severe operating conditions in modern passenger car engines, turbo- or non-turbo charged, and for vans, too. German Gold Engine Power 10W-40 by its optimized formulation provides lowered fuel and oil consumption. Because of its extended viscosity range, the all seasons use is possible. A special booster raises the quality level up to API SN, which provides improved oxidation resistance, improved deposit protection, better wear protection, and better low-temperature performance over the life of the oil. This leads to an improved engine cleanliness and at least to an extended engine life.
