Abstract
Abstract Amides from N-hydrocarbyl hydrocarbylenetriamine, which can be made by the reaction of the appropriate triamine 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.
