Oil is still burned but the burned oilis replaced with fuel and other combustion byproducts. As long as your not consuming a large amount I wouldn't worry about it. 1 qt in 4000 - 5000 miles is more than acceptable in my book. My 330 usually doesn't need any addional oil to meet my 10k mile oil change interval.
