The resulting Group I base stocks can have a viscosity at 100°C and/or a viscosity at \" 40°C that is greater than the corresponding viscosity for a conventional Group I bright stock formed by solvent processing. Addi - 0 tionally, the resulting Group I base stocks can have one or more properties that are indicative of a high quality base stock.
