Abstract
The low temperature properties of a distillate petroleum fuel oil boiling in the range 120.degree. C. to 500.degree. C., are improved particularly the lowering of the cloud point by the addition of a polymer or copolymer of a n-alkyl vinyl or fumarate ester having at least 25 wt. % of n-alkyl groups of average number of carbon atoms from 14 to 18 with no more than 10 wt. % containing less than 14 carbon atoms and no more than 10 wt. % containing more than 14 carbon atoms.
