PURPOSE: To provide a fuel oil that exhibits improved conductivity properties, and an additive system for obtaining the conductivity properties. CONSTITUTION: The composition for fuel oil comprises a fuel oil having an inherent conductivity of less than 10 pS/m; and an additive comprising one of the following component (a), component (b) and component (c): (a) polymetacrylate, polyacrylate or polyfumarate polymer that has a number average molecular weight of about 1,000 to 10,000,000, but is not prepared from a quaternary ammonium monomer; (b) a conductive improver comprising (i) olefin polysulfone, and (ii) a polymeric polyamine reaction product of epichlorohydrin and an aromatic primary monoamine or N-aliphatic hydrocarbyl alkylene diamine, or a sulfonic acid salt of the polymeric polyamine reaction product; and (c) a conductive improver comprising a hydrocarbon soluble copolymer of an alkylvinyl monomer and a cationic vinyl monomer, the copolymer having a ratio of an alkylvinyl monomer unit to a cationic vinyl monomer unit of about 1:1 to about 10:1 and a number average molecular weight of about 800 to about 1,000,000. |
