A lubricant includes a hydrocarbon end group of the formula alkyl-phenol-alkylene oxide-Y wherein Y is the hydrocarbon end group; and wherein the polyalkylene glycol has the formula Z((CH2CH(R1)O)n(CH2CH(R1)O)m)pH wherein Z is a residue of an aryl compound having 1-8 active hydrogens and at least 10 carbons when Z is an aryl group; R1 is hydrogen, methyl, ethyl, or a mixture thereof; n is 0 or a positive number; m is a positive number; and p is an integer having a value equal to the number of active hydrogens, the compound of which Z is a residue, Y replacing the H. A fluid composition for use in refrigeration systems including the lubricant and a refrigerant. A method of lubricating compression refrigeration equipment The lubricant used as a seal swell additive, an additive for compressor and machinery applications, a mineral oil pour point improver, a machinery cleanser, and a carbon dioxide additive.
