Mine was about 1/2 quart low after around 4000 miles. It did not concern me and I added 1/2 quart of 5w20 oil. I have not had to add any more oil since then and it now has almost 7000 miles. I am planning to change the oil one of these days. If it is more than a quart low after only 1000 miles or so you may want to check with the dealer. I don't think that it is too unusual for a new car to burn a little oil while it is first breaking in.
