A lubricant includes a hydrocarbon end group of the formula <?in-line-formulae description="In-line Formulae" end="lead"?>alkyl-phenol-alkylene oxide-Y <?in-line-formulae description="In-line Formulae" end="tail"?> wherein Y is the hydrocarbon end group; and wherein the polyalkylene glycol has the formula <?in-line-formulae description="In-line Formulae" end="lead"?>Z((CH<SUB>2</SUB>CH(R<SUB>1</SUB>)O)<SUB>n</SUB>(CH<SUB>2</SUB>CH(R<SUB>1</SUB>)O)<SUB>m</SUB>)<SUB>p</SUB>H <?in-line-formulae description="In-line Formulae" end="tail"?> 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; R<SUB>1 </SUB>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 above lubricant and a refrigerant. A method of lubricating compression refrigeration equipment, including the step of mixing the above lubricant with a compound chosen from a refrigerant, carbon dioxide, propane, or hydrocarbon gas. The above 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.
