Hydrocarbonaceous distillate fuel compositions and additive concentrates are described that provide improved performance in evaporative burners. The additive components comprise a mixture formed from at least (a) a cyclopentadienyl manganese districarbonyl compound; (b) a succinic derivative ashless dispersant; (c) an aliphatic dicarboxylic acid having at least 24 carbon atoms in the molecule, the two carboxyl groups being separated from each other by at least 6 carbon atoms; and (d) a metal deactivator of the chelation type. Preferably, the compositions also contain (e) alkoxylated alkylphenol; (f) a demulsifying agent; (g) a tertiary monoamine in which each substituent on the nitrogen atom is a hydrocarbyl group; and (h) liquid inert solvent having a final boiling point no higher than approximately 300°C. The compositions are devoid of any metal-containing additive component other than the cyclopentadienyl manganese tricarbonyl compound.
