Abstract
The low temperature properties of a distillate petroleum fuel oil boiling in the range 120.degree. C. to 500.degree. C., and whose 20% and 90% distillation points differ by less than 100.degree. C., and/or whose Final Boiling Point is in the range 340.degree. C. to 370.degree. C. are improved by the addition of a polymer or copolymer having at least 25 wt. % of n-alkyl groups of average number of carbon atoms from 12 to 14 with no more than 10 wt. % containing more than 14 carbon atoms.
