Abstract: The low temperature flowability of a middle distillate petroleum fuel oil, boiling within the range of about 250* to about 700* F. at atmospheric pressure is improved by adding to the fuel oil from about 0.001 to about 1.0 wt. % of a flow improving additive such as a copolymer of ethylene with another ethylenically unsaturated monomer such as an unsaturated ester or an alpha olefin, along with from about 0.01 to about 0.099 wt. % of an essentially saturated hydrocarbon fraction which is substantially free of normal paraffinic hydrocarbons and which has a number average molecular weight in the range of about 600 to about 3000.

Abstract: The response of a middle distillate petroleum fuel oil to the addition of a flow improver, such as a copolymer of ethylene, whereby flow and pumpability at low temperatures are improved, is increased by incorporating said fuel oil a small proportion of a paraffinic wax in sufficient quantity to furnish from about 0.03 to about 2 weight percent of normal paraffin hydrocarbons whose average molecular weight is within the range of from 300 to 650. The paraffinic wax that is added has a molar heat of fusion that is greater than the molar heat of fusion of the first wax that separates from the fuel upon cooling to or below its cloud point. Preferably, the added wax contains normal paraffin hydrocarbons ranging from n-C24 to at least n-C28 inclusive.
