An electrical oil having reduced gassing tendency includes a major amount of a paraffinic or naphthenic basestock and a blend of certain hindered phenols, especially a blend of 2,6-di-t-butyl phenol and 2,6-di-t-butyl cresol. A further enhanced gassing tendency can be provided to the electrical oil by including a tolyltriazole derivative.
