Back in May, I noticed that my 02 Avalanche started to burn oil. It has the 5.3L engine. I got had gotten the oil changed and went from Las Cruces, NM to San Diego, CA and then on to Las Vegas, NV when the check engine oil light came on. Checked the oil, and it needed a quart and a half. Added oil, didn't think too much about it, and drove home the next day. I got home (about 20 miles NW of Santa Fe, NM) and the check oil light came on again. Checked the oil, and I was again a quart low. Added the oil, and said the next time I get to the nearest dealer, I would get it checked out.
I had to go to Las Cruces, NM again a few weeks later, and on the way down, I had to change the oil. After changing the oil, I drove to the dealer (3.5 miles away) and talked to them about the oil loss. No problem, they would start an oil usage test. They needed a mechanic to look at it though, so then wanted me to come back on the following Tuesday. (It was a Saturday.) Anyhow, I drove 800 miles between Sat and Tues and went it and was told I was 2 quarts low, so they topped it off and wanted to continue the testing. We have driven a few trips to Albuquerque and back, and went in and it was 1.5 quarts low. That is the only "official" reading they have because they won't take the proof of an non-dealer oil change 3 days before as proof to the 2 quarts in 800 miles.
Anyhow, my warranty is nearly up (at 33k miles right now). What can I do about this? GM says that using more than a quart of oil per oil change is out of specs. I am sure I am going to get an oil change needed light soon, and am afraid that if I get that done I will go beyond the 36k miles of my warranty and they will tell me F-U when it still burns oil. Any suggestions?
By the way, I bought this used in January and love it, except for the burning of oil.
