Beschreibung
Zusammenfassung:	A lubricating oil base stock including a lubricating oil base stock including from 5 to 50 wt % of 9-methylnonadecane and from 95 to 50 wt % of 9-methyl-11-octylheneicosane. The lubricating oil base stock has a relationship between Noack volatility at 250° C. as measured by ASTM D5800 (y) and kinematic viscosity at 40° C. as measured by ASTM D445 (x) that is less than y=2.15−0.765*ln(x). Also provided is a lubricating oil containing the lubricating oil base stock and one or more lubricating oil additives. A method for improving one or more of thermal and oxidative stability, deposit control and traction control in a lubricating oil by using as the lubricating oil a formulated oil containing the lubricating oil base stock and one or more lubricating oil additives is also provided.
