The composi­ tion has a viscosity (K i ) from v 00 about 1 cSt to about 10 cSt at 100°C as determined by ASTM D445, a viscosity index (VI) from about -100 to about 300 as determined by ASTM D2270, and a Noack volatility of no greater than 50 percent as determined by ASTM D5800. A process for producing the composition, lubricating a oil base stock and lubricating oil containing the composition, and method a for improving one or more of thermal and oxidative stability, solubility and dispersancy of polar additives, deposit control and traction control in a lubricating oil by using as the lubricating oil a formulated oil containing the composition.
