Production of extra-heavy lube oils from Fischer-Tropsch wax

Extra heavy lube base stocks are separated from heavy lube oils with a polar solvent in an amount sufficient to form a first light phase and a second heavy phase. The phases are then separated and the solvent is removed from the second heavy phase to yield an extra heavy lube.
