A composition that includes one or more compounds represented by the formula R1 -- O - R2 wherein R1 is a substituted or unsubstituted aryl or polyaryl group having from about 4 to about 40 carbon atoms, and R2 is the residue of a substituted or unsubstituted glycol ether having from about 4 to about 40 carbon atoms. The composition has a viscosity (Kv100) from about 1 to about 10 cSt at 100°C as determined by ASTM D-445, a viscosity index (VI) from about -100 to about 300 as determined by ASTM D-2270, and a Noack volatility of no greater than 50 percent as determined by ASTM D-5800. The disclosure also relates to a process for producing the composition, a lubricating oil base stock and lubricating oil containing the composition, and a method for improving one or more of oxidative stability, solubility and dispersancy of polar additives of a lubricating oil by using as the lubricating oil a formulated oil containing the composition.
