Ray is correct. My wife's 2006 Impreza with over 200k on the clock gets checked every other time she drives it. I'd do the same with a new one until it breaks in and proves that oil doesn't isn't getting used.
On another note, after a half-day drive there, two days on the track(beating the snot out of it) and another half-day drive home, the Cayman used 4 ounces of oil. It has 107k on it. I'm pretty happy with that.
I nearly found out the hard way. On my maiden voyage, I just happened to check the oil at a second gaz stop and found my oil down a 1/2 quart, I say quart because I was down in Oregon here we say 1/2 a liter.
Even modern cars can and do use oil after a big trip but since no one ever checks their oil no one knows.
