either its burning or you are checking it at the wrong time, check it when it is cold in the morning and you havent started it, and after 2K miles you have literally now oil or is it about a quart low? If you use vtec a lot then a lot of dohc vtec motors tend to use a quart every 3-4k miles especially if you are running it hard, even new cars will use oil if you redline all the time....
