2017 Impreza Oil Consumption - Time to Trade it In?

In the meantime check your oil level every week (unless you want to ruin the engine). Switch to 5W20 or 5W30 synthetic and your oil consumption should be less.

Thank you for your reply! I hadn't thought of switching to 5W, I'll give that a shot.

Yes, you WILL reduce consumption by switching to 5w30, especially in the summer. That said, recall that the dipstick is VERY conservative, reading empty when only 1.5 qts down, and that the oil check-light illuminates when only 1 qt down. So you're consuming 1 qt of 0w20 every 2k miles? That's actually normal for these boxer motors. If you're in a warmer clime I'd even use 10w40 synth...especially in a hot summer. Note that 5w30 is the INTERNATIONAL SUBARU spec outside North America, where SOA was too afraid of very cold start timing chain rattles annoying owners and provoking calls to their Service departments. What a joke....

Your engine will be much happier if you never let if get more than 1/2 quart low. I can tell by the sound if my engine is getting close to 1 quart down.

Oh c'mon! Do you mean only in the first few seconds of a very cold start, or when running at temp? That last quart simply sits atop the sump. Maybe if you consistently corkscrew at 1+g forces you can cause momentary starvation if TWO quarts down? Dunno. I'm feeling one cup of morning espresso down, so need another cup...\that's different scenario, eh?
