ABSTRACT OF THE DISCLOSURE An improved process for the manufacture of synthetic lubricant additives from internal olefins is described. The process utilizes boron trifluoride catalysis with a promoter to produce oligomer mixtures that have surprisingly low viscosities at low temperatures and surprisingly high viscosity indexes as compared with the oligomers found in other methods. It is important that internal olefins be used almost exclusively in the method of this invention.
