Abstract
Abstract Products of reaction between a bis(2-hydroxyethyl)alkylamine or certain higher oxylated members, a dihydrocarbyl phosphite and a boron compound have been found to be effective friction reducers and fuel reducing additives for internal combustion engines when such products are compounded with lubricants and liquid fuels.
