Lubricants comprising 2-hydroxyalkylamide friction modifying compositions
Lubricant compositions comprising an improved ashless organic friction modifier additive, capable of reducing both friction and wear, is provided. It has been found that mixtures of fatty-alkanolamides containing secondary hydroxyls on the amino alkyl substituent, such as amide mixtures prepared from bis(2-hydroxyporopyl)amine and mixtures of at least two different C.sub.8-24 fatty acids, provide better oil solubility and friction reduction than alkanolamides with primary hydroxyl functionality, such as amide mixtures prepared from di-ethanol)amine.
