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 µm.
La présente invention concerne l'amélioration du pouvoir lubrifiant des carburants à faible teneur en soufre, grâce à l'incorporation d'un élément constituant qui est du mazout lourd.
