Abstract
Certain branched carboxylic acids may serve as improved lubricity additive compositions in distillate fuels, and in particular for cold weather applications. Suitable branched carboxylic acids may include, but are not necessarily limited to, isostearic acid, neodecanoic acid, isononanoic acid, neononanoic acid, neoundecanoic acid, isovaleric acid, pivalic acid, and the like and mixtures thereof. The branched carboxylic acids may be used alone or together with straight chain carboxylic acids, and optionally with an aromatic solvent.
