Abstract (en)
A middle-distillate fuel oil composition comprises minor amounts of (A) a quaternary ammonium salt of a polycarboxylic acid; and (B) a polyalkylene amine detergent. The concentrations of (A) and (B) endow the composition with better low temperature properties than a corresponding composition in which (A) is replaced with (Aref), an amine salt of a polycarboxylic acid analogous to (A) and which is not a quaternary ammonium salt; and the concentration of (B) is such that it would adversely affect the low temperature properties of (Aref) in the corresponding composition.
