+1 There has to be some oil in the pistons to allow them to move freely, so you'll burn at least some. If you change your oil frequently, it's usually too little to notice.

FWIW, on my car, the oil sensor has never showed less than full, but I've changed the oil relatively frequently. First at 4000 (I paid for it) and 11500 miles (free 1 year oil change). I'll get another free one around 17500 miles, according to the service indicator.
