    Abstract: A diesel fuel composition made up of a major amount of a diesel fuel, a minor amount of at least one metallic species and a minor amount of a detergent additive is disclosed. The detergent additive includes a compound of formula: wherein:each Ar independently represents an aromatic moiety having 0 to 3 substituents selected from the group consisting of alkyl alkoxy, alkoxyalkyl, hydroxy, hydroxyalkyl, halo and combinations thereof or additionally, in the case of formula II, acyloxy, acyloxyalkyl, aryloxy, aryloxy alkyl, halo and combinations thereof, each L is independently a linking moiety comprising a carbon-carbon single bond or a linking group;each Y is independently a moiety of the formula H(O(CR2)n)yX—, wherein X is selected from the group consisting of (CR′2)2, O and S; R and R′ are each independently selected from H, C1 to C6 alkyl and aryl; z is 1 to 10; n is 0 to 10 when X is (CR′2)7, and 2 to 10 when X is O or S; and y is 1 to 30; each Y′ is independently a moiety of the formula Z(O(CR2)n)yX—, wherein X is selected from the group consisting of (CR′2)2, O and S; R and R′ are each independently selected from H, C1 to C6 alkyl and aryl; z is 1 to 10; n is 0 to 10 when X is (CR′2)z, and 2 to 10 when X is O or S; y is 1 to 30; Z is H, an acyl group, an alkyl group or an aryl group;each a is independently 0 to 3, with the proviso that in formula (I), at least one Ar moiety bears at least one group Y; and with the proviso that in formula (II), at least one Ar moiety bears at least one group Y′ in which Z is not H; and m is 1 to 100.
