摘要: This invention relates to lubricating oil additives, and compositions, their method of preparation, use. More specifically, this several novel additives compositions which contain a tungsten compound an antioxidant, namely aminic antioxidants such as secondary diarylamine or alkylated phenothiazine. The use the with and/or phenothiazine provides improved oxidation deposit control compositions. are particularly useful crankcase transmission lubricants, gear oils other high performance lubricant applications.
