摘要: A binary two phase engine oil composition having two substantially immiscible liquid phases exhibits improved fuel economy which is maintained over an extended period. The first liquid phase comprises a base oil, natural or synthetic. The second liquid phase is a polar organic liquid, preferably a complex alcohol ester, preferably derived from a polyol, a polybasic acid, and a monohydric alcohol.
