Abstract: An automatic transmission fluid basestock of mineral oil origin is produced from a neutral distillate fraction, preferably a medium neutral distillate, by severe furfural extraction to a dewaxed oil equivalent VI of about 95, severe hydrocracking, at temperatures ranging from at least about 700.degree. F. and pressures of at least about 1,500 psig, to achieve a minimum product VI of 120. The hydrocracked product is vacuum distilled to recover a lubricant oil product boiling above about 650.degree. F. which has a VI of at least 120 and a viscosity at 100.degree. F. of at least 100 SUS. The viscosity of the 120 VI product can be increased by increasing the distillation cut point without impacting the VI. The lubricant oil, having a wax content below 30 wt. %.
