Abstract (en)
A method of improving the low temperature properties of a middle distillate fuel composition comprising:(a) a nitrogen-containing dispersant; and(b) one or more low temperature property enhancers which are not fumarate vinyl ester copolymers and which are selected from (x) wax antisettling additives; (y) middle distillate flow improvers and mixtures thereof;the method comprising adding to the fuel an additive (c) which is a copolymer comprising units of formula (A):and units of formula (8):wherein R is an alkyl group and each of R<sup>1</sup> and R<sup>2</sup> is an alkyl group.
