Fuel additive compositions for enhancing the lubricity of hydrocarbon fuels in which the natural lubricity has been diminished due to treatment of the fuel to reduce sulfur and aromatic components for improved emissions are disclosed. Preferably, the fuel additive compositions include (1) a polyalkenylsuccinimide having a high molecular weight; (2) a low aromatic paraffinic base oil; and (3) a low aromatic petroleum distillate to impart improved lubricity to hydrocarbon fuels.
