Much of the oil consumption issues with the 3rd gen prius has been traced to the egr. Its an easy fix. Take it out, clean it and put it back in. They get clogged and cause oil burning. While in there add an oil catch can. I do the egr cleaning every 50k on mine. Costs me a can of oven cleaner and two hours. 160k and zero oil loss between oil changes.
