    • Fuel oil compositions which contain detergent species and are susceptible to the formation of wax at low temperatures are provided, and a method for improving detergency properties of a fuel oil while avoiding an adverse effect of the fuel oil on the cold-flow properties is provided, wherein the use of alternative species to the conventionally used fuel oil detergents does not have an adverse effect on the cold-flow performance of wax anti-settling additives in addition to providing of the detergency properties. A fuel oil composition comprises: 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 reaction product of a hydrocarbyl-substituted succinic acid or anhydride and hydrazine. As a method of improving detergency properties of a fuel oil composition comprising a major amount of a fuel oil and a minor amount of (a) at least one polar nitrogen compound effective as a wax anti-settling additive while not substantially adversely affecting cold flow properties of the fuel oil composition, the method comprises adding to the composition a minor amount of (b) at least one reaction product of a hydrocarbyl-substituted succinic acid or anhydride and hydrazine.

    • Improvement methods of fuel oil compositions and fuel oil compositions are provided to contain detergent species and be susceptible to the formation of wax at low temperatures, wherein low temperature properties of the fuel containing a wax anti-settling additive and a polyamine detergent can be restored by the additional presence of a third co-additive species. As a method of improving 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 (c) at least one acidic organic species to the composition. The at least one polar nitrogen compound comprises an oil-soluble polar nitrogen compound having one or more, preferably two or more, substituents of the formula >NR^13, where R^13 represents a hydrocarbyl group containing 8 to 40 atoms, wherein the substituent or one or more of the substituents may be formed in the form of a cation derived therefrom. The at least one polar nitrogen compound comprises an amide-amine salt formed by reacting one molar proportion of phthalic anhydride with one molar proportion of dihydrogenated tallow amine. The at least one polyamine detergent comprises a reaction product of a poly(isobutene) substituted succinic anhydride acylating agent and a polyamine or a mixture of polyamines. The acidic organic species comprises an unsaturated monocarboxylic acid having 8 to 30 carbon atoms, preferably 12 to 22 carbon atoms.
