    Abstract: It has been discovered that compositions that are blends or mixtures of certain lubricity additives and corrosion inhibitors and/or stability additives can serve as improved lubricity additive compositions in distillate fuels. The corrosion inhibitors may include, but are not necessarily limited to, saturated or unsaturated monomer, dimer, and trimer fatty acids, succinic acids, imidazolines, and mixtures thereof. Suitable stability additives include, but are not necessarily limited to, amines, amides, amine/aldehyde condensates, polymer dispersants, and mixtures thereof, where the stability additive is different from the lubricity additive. It has been surprisingly discovered that less lubricity additive may be used in the compositions when the stability additive or corrosion inhibitor is present to achieve the same lubricity result, as compared with compositions that do not contain a stability additive or corrosion inhibitor, yet the same total amount of additive composition.
