Abstract
The lubricity of low sulfur content middle distillate fuel oil boiling over a temperature range of 100.degree.C. to 500.degree.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.degree.C., of at most 500 .mu.m.
