1. A diesel fuel composition comprising a major proportion of a diesel fuel and:
from 50 to 5000 ppm of a first additive (i) comprising one or more of:
(a) the reaction product of a carboxylic acid selected from nitrilotriacetic acid, ethylenediamine tetraacetic acid and propylene-1,2-diamine tetraacetic acid and an amine selected from dioleylamine, dipalmitamine, dicoconut fatty amine, distearylamine, dibehenyl amine, ditallow fatty amine and hydrogenated ditallow fatty amine;
(b) the reaction product of maleic anhydride and an amine selected from coconut amine, tallow fatty amine, oleyl amine, arachidyl amine, tridecyl amine and behenyl amine; and
(c) the reaction product of polyethylene polyamines having 2 to 6 nitrogen atoms and fatty acids having 16 to 20 carbon atoms; and
from 50 to 5000 ppm of a second additive (ii) which is a terpolymer obtained by reacting monomers of:
(x) ethylene;
(y) vinyl or propenyl esters of C1 to C20 carboxylic acids; and
(z) a third monomer different to (x) and (y) comprising an alkene functional group selected from:
an α-olefin;
an α,β unsaturated carboxylic acid or an ester thereof; and
an ester of an unsaturated alcohol,
wherein the diesel fuel comprises mineral diesel and at least 5 vol % of a renewable diesel fuel obtained by the hydrodeoxygenation of fats and oils; and
wherein the diesel fuel composition has an improved performance in a low temperature flow test (as defined in ASTM D4539 or CAN CGSB-3.0, no. 140.1-2017) as compared to the same fuel without the first additive (i) and the second additive (ii).
