I've had oil consumption ever since I bought the car 4 years ago at 45k miles. It was mostly a quart per 5k miles for 3.5 years until my AOS blew last fall. I replaced the AOS but my oil consumption vastly increased. I replaced the AOS again (assuming the new one was faulty) along with the PCV but the consumption remained high. No drips underneath. No unusual visible tailpipe smoke. Water fluid is clean. I did compression/leak down tests and the numbers were good.

I've now burned 7 quarts in the last oil change cycle of 5k miles with the car at 92k miles. Where else could my oil be going?
