Disclosed is a method of simultaneously manufacturing high quality naphthenic base oil and heavy base oil using a single catalyst system, by subjecting an oil fraction (slurry oil or light cycle oil) produced by fluid catalytic cracking and an oil fraction (deasphalted oil) produced by solvent deasphalting to hydrotreating, catalytic dewaxing and hydrofinishing of the single catalyst system, thereby obtaining not only products having low viscosity but also heavy base oil products (150BS) having high viscosity which was impossible to obtain using a conventional catalytic reaction process, and also thereby producing base oil products having different properties using the single catalyst system, thus generating economic benefits and exhibiting superior efficiency.
