| 摘要 |
A method of preparing a fuel composition containing a distillate fuel, a detergent additive and a cold flow additive, of a further additive selected from (a) acids and mixtures thereof; and (b) lubricity enhancing additives are provided, for the purpose of reducing the effect of the detergent additive on the cold flow performance of the composition, and/or improving the cold flow performance of the composition, and/or reducing the amount of cold flow additive in the composition, and/or increasing the concentration of detergent additive in the composition without undue impairment of the cold flow performance. The further additive is preferably selected from carboxylic acids, more preferably fatty acids, and mixtures thereof. The distillate fuel is preferably a middle distillate fuel. The overall fuel composition is preferably an automotive fuel composition, more preferably a diesel fuel composition.
