Abstract
A low viscosity oil has more than 50% by weight of 9-methylnonadecane. A lubricating composition has this low viscosity oil as base oil and, optionally, another base oil or an additive. The low viscosity oil has a kinematic viscosity at 100° C., measured by the ASTM D445 standard, of 0.5 to 2.5 mm2s−1. The low viscosity oil can be prepared using a metallocene catalyst, and the low viscosity oil can be used as high performance lubricant for lubrication in the field of motors, hydraulic fluids and gears, in particular bridges and transmissions.
