I typically burn half a quart to a quart between oil changes (~5k miles). The top hole on the dipstick to the bottom hole is a quart. This is normal, modern engines burn oil on purpose.
While it would be a bit odd for an engine to suddenly behave differently, it could be that you just started noticing at 17k? Perhaps your driving changed a bit (different commute, more aggressive on throttle, etc)?
Also, it's entirely possible the dealer filled it half a quart less than maximum for one reason or another. Oil fill isn't the most precise of measurements.
