Abstract: Lubricant compositions having improved load carrying capacity comprising an extreme pressure compound comprising a sulfur-containing compound, a load carrying capacity enhancing combination comprising a hydrocarbylamine compound and an alkylphosphorothioate compound, a friction modifier compound, and a diluent or base oil as applicable. These lubricant compositions can be used as industrial oils well-suited for the demands of geared device applications, such as in wind turbine gear-boxes and automotive gears and axles.

Abstract: Lubricant compositions having improved anticorrosion performance comprising an extreme pressure compound comprising a sulfur-containing compound, an antiwear compound comprising a phosphorous-containing compound, an alkylene amine friction modifying compound, a dispersant compound containing basic nitrogen, and a diluent or base oil as applicable, wherein any of compounds other than the diluent or base oil can be the same or different compounds. These lubricant compositions provide improved anticorrosion resistance and fatigue performance, which prolongs service lives of lubricated parts, especially those used in outdoor applications.

Abstract: A method of enhancing the operation of diesel fuel combustion systems in a combustion system includes supplying a fuel and additive that includes a manganese compound to a diesel fuel combustion system. The fuel is then combusted in the combustion chamber to produce at least one byproduct including the manganese compound. The manganese compound is supplied in an amount effective to complex with the combustion byproduct. The diesel fuel combustion system operation is enhanced by improving the attributes of lubricating oil loaded with the combustion byproduct soot particles.
