I would suggest that add a single bottle after the 3000 mile rinse. That is some heavy oil consumption. I am wondering if you might have some blocked drain holes in the heads of the motor. When this happens oil gets pumped up to the top end of the motor faster than it can gravity feed back down to the oil pan for recirculation. So under the valve covers the area gets flooded with oil. And quite possibly the oil is getting sucked out through the PCV valve and into the intake and gets burned off. Also this could be the reason for the heavy smoke in the cold morning starts. Excessive oil sits on top of the valves for a longer than normal period of time. Some oil slips past the valve stem seals and down on top of the piston crowns. So when you start the cold motor that oil burns off the top of the pistons.
Many times if the oil draining from the heads are restricted and not totally blocked this will be remedied from the Auto-RX cleansing. However, if they are blocked solid, then it might be necessary to poke open the drain holes in the head. Auto-Rx can only clean where the oil can flow.
