ABSTRACT:
A metal-containing lubricant composition containing an overbased copper metal-containing compound is disclosed which improves high speed, high temperature operation of gasoline and diesel engines. The overbased copper metal-containing compound acts as a dispersant/detergent and oxidation and corrosion inhibitor and avoids the acceleration of wear rates typical of many copper compounds.
