07 Sub oil usage?
Wife's 07 loaded up Sub....optioned to the max and the flex 5.3. Always change oil between 3500 and 4000 miles. Has about 70k on it. Will use over a quart between changes...almost 2!. No leaks and no noticable smoke. What am I missing? Mostly 2 lane highway used and never pulled with.
