    Abstract: A gasoline composition contains an organometallic compound of formula Mea(R)x(CO)y where Me is chromium, molybdenum, manganese, iron, cobalt or nickel a is 1 to 4, R is an aromatic ligand, x is 0 to 5, and y is 0 to 9, both x and y not being zero at the same time, and as a stabilizer for the organo-metallic compound an artificially aged phenylene diamine of formula: where R and R1 are alkyl or aryl radicals having 3 to 7 carbon atoms. The phenylene diamine is artificially aged by exposure to light, or by oxidation with peroxides or oxygen, or by adding traces of metal, so that its solution in a liquid hydrocarbon has a colour which absorbs light rays of wavelengths of 350 to 550 millimicrons. The composition contains 0.01 to 0.3% by weight of the organo-metallic compound, and 0.001 to 0.3% by weight of the phenylene diamine, and may contain 0.001 to 0.2% by weight of an aliphatic long-chained fatty amine. In examples gasoline contains methylcyclopentadienyl manganese tricarbonyl, cyclopentadienyl manganese tricarbonyl, dimestiylene chromium, dicyclopentadienyl nickel and molybdenum hexacarbonyl; N,N1-di-secondary-butyl-p-phenylene diamine aged by exposure to sunlight and by treatment with reformed gasoline containing peroxides, N,N-1di-benzyl-p-phenylene diamine, N-butyl-N1-propyl phenylene diamine and N,N1-di-isobutyl-p-phenylene diamine, the last three being aged by exposure to sunlight; oleylamine and laurylamine, and red dyestuff. Lists of aromatic liquids which may be present in the organometallic compounds and suitable phenylene diamine derivatives, are given.
