  • Railway lubricating oil
    Patent number: 4820431
    Abstract: Disclosed is a lubricating oil composition for enhanced protection against silver wear in railway diesel engines which is formulated with no chlorinated hydrocarbons or with reduced levels thereof. The composition comprises a silver protective compound selected from the group consisting of (1) C.sub.8 to C.sub.22 fatty acid esters of C.sub.1 to C.sub.12 polyhydroxy alcohols or mixtures of such esters, wherein the alcohol portion of the ester has at least two unesterified hydroxyl groups; and (2) a mixture comprising the polyhydroxy compound of (1), above, and a chlorinated paraffin.
    Type: Grant

  • Metal-containing lubricant compositions
    Patent number: 4767551
    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.
