Bill you are lucky. My 07 Avalanche would burn almost a quart of oil in between 3000 mile oil changes. I looked online and found that to be normal. I loved my avalanche but it had constant minor issues. Air ride went out twice,fuel sending unit, air control unit,cruise switch and a tranny. All within 18 months. Sold it and got a Dodge 2500 with 5.9 Diesel and haven't had one issue in 7 months. I never thought I would own a dodge. Now im not sure I will buy anything but.
