The use of a complex ester obtainable by esterification reaction between aliphatic linear or branched C- to C-dicarboxylic acids, aliphatic linear or branched polyhydroxy alcohols with 3 to 6 hydroxyl groups, and, as chain stopping agents, aliphatic linear or branched C- to C-monocarboxylic acids or aliphatic linear or branched monobasic C- to C-alcohols, as an additive in a fuel for minimization of power loss in the operation of an internal combustion engine with this fuel.

Use of a complex ester to reduce fuel consumption

A lubricant composition includes a base oil, an alkoxylated amide, an ester, and an anti-wear agent including phosphorus. The alkoxylated amide and ester have general formulas (I) and (II), respectively. The lubricant composition may be further defined as a racing oil composition. Also disclosed is a method for maximizing the effectiveness of a friction modifier in a racing oil composition thus increasing the fuel economy of a racing vehicle. The method includes providing the racing oil composition and lubricating an internal combustion engine of a racing vehicle to increase the fuel economy of the racing vehicle.
