Abstract: The present invention relates to additives for enhancing the lubricity of hydrocarbon fuel oils, the inventive additive composition including one or more of the reaction products of (i) an alkylated polyamine and (ii) urea or isocyanate, or the salt adducts of these reaction products. More particularly, the present invention provides for a process for improving the lubricity of hydrocarbon fuel oils, which are low in inherent lubricity due to treatment to reduce sulfur and aromatic components for improved emissions.
