Low tension rings to extend engine life are the general cause of this oil consumption issues in the 5.3. all of the 5.3s Ive owned have used some oil (02-08) but none were what I would consider excessive. never had one more than 1 quart low at oil changes @ 5000 miles. All had miles ranging from bought new to 226K. I would not hesitate to purchase any of the Non AFM 5.3
