Abstract
A reaction product of at least one C.sub.5 -C.sub.60 carboxylic acid and at least one amine selected from the group consisting of guanidine, aminoguanidine, urea, thioruea and the salts thereof is disclosed as an additive for hydrocarbon fuels. The reaction product is added to a fuel, such as gasoline, at levels of from about 5 pounds of reaction product per thousands barrels of fuel (PTB) to about 100 PTB to increase the lubricity of the fuel and thereby reduce the wear occasioned upon the fuel pump. A composition comprising a hydrocarbon fuel and the reaction product is also disclosed.
