    Abstract: Fuel composition for internal combustion engines which comprises a larger portion of fuel and a smaller quantity of a composition of hydrocarbon oligomers almost totally saturated, characterized in that the above composition of almost totally saturated hydrocarbon oligomers: 1) is obtained by the oligomerization and subsequent hydrogenation of a hydrocarbon composition comprising basically C.sub.13 -C.sub.18, preferably C.sub.15 -C.sub.16, internal oligomers, in a quantity of more than 90% by weight, 2) is basically without any possible hydrocarbons having a number of carbon atoms equal to or less than 13, 3) has a viscosity at 100.degree. C. of betweem 5.0 and 12.0 cSt, particularly from 7.3 to 8.4 cSt.

    Abstract: 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 tricarbonyl 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.degree. C. The compositions are devoid of any metal-containing additive component other than the cyclopentadienyl manganese tricarbonyl compound.
