摘要

A method of improving the low temperature properties of a fuel oil composition comprising a major amount of a fuel oil and minor amounts of (a) at least one polar nitrogen compound effective as a wax anti-settling additive and (b) at least one polyamine detergent. The method comprises adding to the composition (c) at least one acidic organic species. A use and a process of improving the low temperature properties of the fuel oil composition are also described.
