Abstract
A fuel composition and method for reducing friction or wear and improving fuel economy in an engine. The fuel composition includes gasoline and from about 10 to about 750 ppm by weight based on a total weight of the fuel composition of a hydroxyalkyl hydrocarbyl-substituted succinimide compound having at least two hydroxyl groups attached to a tertiary nitrogen atom of a polyamino group through a hydrocarbyl link, wherein the hydroxyalkyl hydrocarbyl-substituted succinimide is devoid of primary and secondary amino groups.
