Abstract
Improved organic anti-wear additive compositions are disclosed containing certain citric acid esters, e.g., mixtures comprising citrate oligomers, and fatty acid alkanolamides. The combination exhibits excellent and synergistic anti-wear activity in lubricants. The compositions of the invention beneficially allow one to reduce amounts of zinc and phosphorus that are often used in lubricants, while boosting anti-wear performance and maintaining, and often enhancing, friction reduction properties.
