A friction modifier for combustible fuels is provided that is prepared by combining a saturated carboxylic acid and an alkoxylated amine or etheramine. Furthermore, there also is an additive concentrate for use in fuels, especially in gasoline for internal combustion engines, comprising (a) a friction modifier comprising of a branched saturated carboxylic acid salt of an alkoxylated amine, such as isohexyloxypropylamine isostearate; (b) a detergent package, as well as the combustible fuels containing this additive concentrate. The particular selection of friction modifier (a) enables a stable additive concentrate to be formulated providing a significant benefit in friction loss when incorporated in gasoline used to fuel an internal combustion engine, and hence an improvement in fuel economy. Moreover, the use of the friction modifier (a) in combination with a detergent package permits increased fuel efficiency to be obtained without increasing the incidence of IVD deposits in combustion engines running on a fuel modified with the additive concentrate.
