An additive for transformer oils comprising a non-ionic fluorosurfactant and a halogenated hydrocarbon where the co-mixture is a liquid at least 70°F. and methods for preparing and using same. The halogenated hydrocarbon is preferably chosen from the group comprising C1-C3 alkanes which can be fully halogenated or can retain some hydrogen atoms on the structure. The most preferred halogenated hydrocarbons being dibromotetrafluoroethane, dibromodifluoromethane or bromochloromethane. The most useful surfactants for use in this invention are those that are capable of dispersing and holding a halogenated hydrocarbon evenly throughout an oil. This is best accomplished through use of a non-ionic fluoro-surfactant. The additive of this invention can be used with any transformer oil to increase the useful life of the oil as well as to enhance the operational parameters of the transformer.
