Abstract
Abstract N-Hydrocarbyl hydrocarbylenediamine carboxylates, which can be made by the reaction of the appropriate diamine and organic monocarboxylic acid, demonstrate friction reducing properties when formulated into lubricants, particularly lubricating oils, and fuel consumption reduction properties when formulated into such lubricants or into fuels.
