I have about 250,000 miles on my 04 and it started burn oil about 1 year ago. I have to add 1Quart every 1000 miles and i am tired of it. It does not matter what kind of oil, synthetic or convention, still burn oil bad. So I tried to use sea foam and it fix the problem. Now it burn no oil with mobile 1 after 2000 miles. I made a video of it.
