Stay away from high mileage or thicker oils, those are for people that don't know what they are doing, first you need to see why the engine is consuming oil, it could be from 3 places: the crankcase ventilation, the valve stem seals or the piston rings. Once that you know from where the oil is coming you need to fix it, simple as that.
Any other trick (motor honey, high mileage or thicker oil) is just homeopathy for your car.
