Abstract
The present invention discloses aryl-polyalkylene glycol monoester compound compositions that are suitable for use as a base oil, particularly a base oil for use as an automotive lubricant. The compositions can generally be characterized by having low kinematic viscosity at 100° C. high viscosity index and low Noack volatility. The present invention also discloses lubricant formulations including such aryl-polyalkylene glycol monoester compounds with other materials such as an API Group I-V base oil and/or additives.
