摘要：
The fuel economy of an internal combustion engine can be improved by adding to the lubricating oil used to lubricate the crankcase of said engine a synergistic blend of amine/amide and ester/alcohol friction modifying agents, for example, by reacting (a) a carboxylic acid, such as oleic acid and/or isostearic acid with an amine, such as diethylene triamine or tetraethylene pentamine, and (b) glycerine monooleate and/or glycerine monoricinoleate.
