A fuel oil composition comprising a major amount of fuel oil and a polymeric additive of Mn 1,000 to less than 3,000. The polymeric additive comprises the condensation reaction product of an aliphatic aldehyde having 1 to 4 carbon atoms and a mixture of alkylphenols comprising a major amount of a monoalkylphenol with more than 10 to less than 35 mole % of a dialkylphenol. The alkyl groups of the phenol have 1 to 20 carbon atoms. The polymeric additive is useful for improving the low temperature flow properties of a fuel oil. |
