PURPOSE:An additive having an inorganic substance such as a metallic compound, etc., in high concentration and improved compatibility with fuel oil, comprising a composition as an active ingredient obtained by dispersing a bivalent - tetravalent metallic oxide(hydroxide) subjected to adsorption treatment with a specific compound into water by the use of a water-soluble surface active agent. CONSTITUTION:The aimed fuel additive comprising a composition as an active ingredient obtained by dispersing fine particles of one or more oxides(hydroxides) of bivalent - tetravalent metals selected from Mg, Ca, Al, Ba, Mn, Cu, Zn, Fe, Cr, Ti, Sn, Mo and Co having 100-600Angstrom particle diameters subjected to adsorption treatment with one or more of naphthenic acid, tall oil fatty acid, alkylphosphoric acid ester, oleic acid and lauric acid into water by the use of a water-soluble surface active agent.
