1. A method of reducing foam in a diesel fuel, said method comprising adding from 2 ppm to 100 ppm of at least one poly(acrylate) polymer to the diesel fuel wherein the at least one poly(acrylate) polymer is prepared by polymerizing:
(i) a (meth)acrylate monomer comprising tertiary butyl (meth)acrylate; and
(ii) a (meth)acrylate monomer comprising trimethylhexyl (meth)acrylate and/or 2-ethylhexyl (meth)acrylate; and
wherein the ratio of monomer (i) to monomer (ii) ranges from 90:10 to 98:02; and
wherein the at least one poly(acrylate) polymer has a weight average molecular weight (“Mw”) from 10,000 to 350,000 Da.
