    Abstract: An additive composition comprises at least one polyoxyalkylene compound and at least one ethylene polymer, wherein the at least one ethylene polymer, in addition to units derived from ethylene, comprises units of the formula (I): and optionally, units of the formula (II): wherein each R1 group independently represents hydrogen or methyl; wherein each R2 group independently represents an alkyl group having 5 or more carbon atoms; wherein each R3 group independently represents hydrogen or methyl; wherein each R4 group independently represents an alkyl group having between 1 and 4 carbon atoms; wherein the proportion of units of formula (I) in the ethylene polymer is between 16 and 30 mol %; and wherein the total proportion of units of formula (I) and formula (II) in the ethylene polymer is between 19 and 30 mol %. The composition is particularly suitable for improving the low temperature properties of fuels having sharp distillation tails and low final boiling points.

    Abstract: Additive compositions comprising: (i) at least one oil-soluble hydrogenated block diene polymer, comprising at least one crystallizable block, obtainable by end-to-end polymerization of a linear diene, and at least one non-crystallizable block, the non-crystallizable block being obtainable by 1,2-configuration polymerization of a linear diene, by polymerization of a branched diene, or by a mixture of such polymerizations, (ii) at least one ethylene-unsaturated ester compound; and (iii) at least one comb polymer. The additive compositions are used to improve cold flow characteristics in fuel oils. The additive compositions are particularly effective in fuel oils having a 90-20% boiling temperature range, as measured in accordance with ASTM D-86, of more than 115° C., preferably more than 120° C., more preferably more than 130° C., and most preferably more than 140° C., and a final boiling point of more than 370° C., preferably more than 380° C., and most preferably more than 390° C.
