Abstract: The low temperature flowability of a middle distillate petroleum fuel boiling within the range of about 250* and about 700*F. at atmospheric pressure is improved by adding to the fuel a combination of a microcrystalline petroleum wax and a wax modifying additive which comprises either a polymer containing halogenated polymethylene segments or an N-aliphatic hydrocarbyl succinamic acid or a derivative thereof. The invention is particularly advantageous in improving the flow of a diesel fuel through a fine filter at low temperatures.
