Abstract
A fuel oil composition comprises a fuel oil blend, at least one ethylene-vinyl ester polymer and at least one polyalkylmethacrylate polymer. The fuel oil blend comprises a middle-distillate fuel oil and a hydrotreated vegetable, animal or fish oil, wherein the amount of hydrotreated vegetable oil in the fuel oil blend is sufficient to provide the blend with an increase in the C15 to C20 n-alkane distribution of at least 3% by weight over the C15 to C20 n-alkane distribution of the middle-distillate alone.

A fuel oil composition comprising a fuel oil blend, at least one ethylene-vinyl ester polymer and at least one polyalkylmethacrylate polymer, wherein the fuel oil blend comprises a middle-distillate fuel oil and a hydrotreated vegetable, animal or fish oil, and wherein the amount of hydrotreated vegetable oil in the fuel oil blend is sufficient to provide the blend with an increase in the C15 to C20 n-alkane distribution of at least 3% by weight over the C15 to C20 n-alkane distribution of the middle-distillate alone.
A method of improving the low temperature properties of a blend of a middle-distillate fuel oil and a hydrotreated vegetable, animal or fish oil comprising adding to the blend at least one ethylene-vinyl ester polymer and at least one polyalkylmethacrylate polymer, wherein the amount of hydrotreated vegetable oil in the blend is sufficient to provide the blend with an increase in the C15 to C20 n-alkane distribution of at least 3% by weight over the C15 to C20 n-alkane distribution of the middle-distillate alone.
