The invention relates to a lubricating oil base oil comprising a lubricating oil base oil comprising 5 to 50% by weight of 9-methylnonadecane and 95 to 50% by weight of 9-methyl-11-octylenecosan. The lubricating oil base oil has a relationship between Noack volatility at 250 ° C, as measured according to ASTM D5800, (y) and kinematic viscosity at 40 ° C as measured according to ASTM D445. , (x) which is smaller than y = 2.15-0.765 * ln (x). The invention also relates to a lubricating oil containing the lubricating oil base oil and one or more lubricating oil additives. The present invention also relates to a method for improving one or more of thermal stability and oxidation, regulation of deposits and traction in a lubricating oil by the use, as a lubricating oil, of a formulated oil containing the lubricating oil base oil and one or more lubricating oil additives. |
