Claims15
A lubricant composition comprising a major proportion of an oil lubricating viscosity and a minor antioxidant or antifriction amount of a product of reaction made by reacting a N-hydroxcarbyloxyhydrocarbyleneamine of the formula ##STR3## wherein R is a hydrocarbyl group containing 6 to 30 carbon atoms, R.sup.1 and R.sup.2 are hydrocarbylene groups containing 2 to 3 carbon atoms and R.sup.3 is hydrogen or a C.sub.1 to C.sub.5 hydrocarbyl group with a boron compound.
A method for decreasing fuel consumption of an internal combustion engine by lubricating the parts of said engine with a lubricant composition comprising a major portion of an oil of lubricating viscosity and a minor antioxidant or antifriction amount of a product of reaction made by reacting a N-hydrocarbyloxyhydrocarbylenediamine of the formula ##STR4##
