Polyoxyalkylene esters, ethers, ester/ethers or mixtures thereof containing two C/sub 10/-C/sub 30/ linear saturated alkyl groups and a polyoxy (C/sub 1/-C/sub 4/) alkylene glycol group of molecular weight 200 to 5,000 have been found to be effective distillate fuel flow improvers, especially for narrow boiling distillates hitherto difficult to treat, they may also be used in combination with conventional additives such as ethylene/unsaturated ester copolymers and nitrogen compounds such as diamides or amide/amine salts, ester/amides of dicarboxylic acids.
