Have you changed your driving pattern. I had a car once that burned no oil between changes when driving it at low speeds, less than 50 MPH, but then I drove on the freeway for a couple hundred miles and oil was so low the hydraulic lifters rattled due to low oil when going around a curve. The causes of high oil consumption are intake valve guide seals and oil rings that have lost it or perhaps the PCV valve that sucks the blow-by out of the crankcase is plugged Put in a new PCV valve and have the valve guide seals renewed and then check oil every time you fill with gas. If the high oil usage continues too high for you time to renew the engine or trade in the car.
