Heat transfer, lubricating, functional and/or insulating fluid compositions for use in apparatus such as electrical transformers contain up to 25 weight percent of one or more oil additives and a 1-octene and/or 1-decene dimer and/or a 1-octene and 1-decene co-dimer oil having improved low temperature properties which oil contains less than about 2.5 weight percent of, respectively, the 7-methylpentadecene, 9-methylnonadecene and, 7- and 9-methylheptadecene isomers. The dimers can be hydrogenated to provide the saturated counterparts of the isomers.
