Process for the preparation of a lubricating base oil with a high viscosity index and a low pour point by catalytic dewaxing, which process comprises contacting under dewaxing conditions a feedstock containing at least part of the hydrocrackate of a wax-containing mineral oil fraction, which feedstock has a kinematic viscosity at 100 °C of at most 10 mm2/s, with a dewaxing catalyst. The invention further provides a lubricating mineral base oil comprising hydrocarbons with a boiling point of at least 250 °C, and having a viscosity index of at least 125 and a pour point of at most -20 °C.
