I had an 07 lbz and I always just went by the oil life monitor so I can't tell you the mileage between changes. Anyways my 07 would use about a quart to quart and a half of oil between oil changes. I put over 900,000 Mike's on that truck and it was consistent since day one on oil consumption. Fast forward to now and my 17 L5P. This thing...twice now, has not read on the dipstick when I would change it. It has 140,000 miles now. I know some of you will say I need to check it often between changes, but I don't and feel like I shouldn't be worried about running low on a new vehicle. What have you all noticed about oil consumption on your trucks?
