    Abstract: An additive concentrate comprises a lubricity enhancer dissolved in a solvent. The lubricity enhancer comprises from 10 to 90% by weight of the concentrate and is a salt formed by the reaction of a carboxylic acid with di-n-butylamine or tri-n-butylamine. The concentrates have excellent low temperature stability.

    Abstract: The lubricity of low sulfur content middle distillate fuel oil boiling over a temperature range of 100°C. to 500°C. is enhanced by incorporation of a heavy fuel component having hydrocarbon components resulting from distillation of a crude oil, whereby the incorporation of the heavy fuel component increases at least one of (a) the 50% distillation temperature, and (b) the polynuclear aromatic content of the composition, and wherein the composition gives a wear scar diameter, as measured by the HFRR test at 60°C., of at most 500 &mgr;m.
