My 2007 gmc yukon xl burned a quart of oil from 29,000 mile to 32,000 miles. now it just bruned another quart at 35,000 miles. was told by the dealer that they have had some similar complaints. what's your advice

You may have already been informed of this, but there is a TSB on this issue. I too spent nearly a year on the so-called consumption tests. Kept getting the run around and told that 2 quarts or more in less than a 3000 miles was within "specs". I finally contacted GM directly and got more of the run around. I believe they were all aware of the issue and didn't want to deal with it. The bulletin pertaining to the excessive oil consumption pertains to nicks in the valve stems. After burning through almost 3 quarts while driving 400 miles to Oklahoma, a GM dealers service dept. there told me about the bulletin(mind you I had had in to my dealer no fewer than 8 times). Voila! Now they are taking care of it. Have to tear the whole engine down and my car will likely be gone for a month. Amazing quality for a 50k car!

My first question is, is the vehicle still under factory warranty at 35,000 miles? If it is have it checked out by the dealer. Aside from that there are situations of oil burn that fall into limits by the manufacturer, however, 1 qt every 3000 miles on a vehicle that new seems excessive. Your dealer should be able to provide you with the manufacturers limits as it's stated in the vehicles service manual on your vehicle. But make sure they give you a copy of the page not just hear it by word of mouth. If there are no external oil leaks on your engine then it has to be burning it internally which would mean the only way to find any worn parts would be tear down of the engine to identify them. There are a few things you can try before going to that extreme especially if your truck is running fine. Try a different grade of oil or switch to synthetic oil. Make sure you change all filters, pcv valve and maintenance items as prescribed in your owners manual at the time recommended depending upon your driving habits. Keep it well tuned.
If your dealer said this was a problem they've had similar complaints on there's a possibility there's a TSB (technical service bulletine) out on the vehicle for the problem. Which means the manufacturer is aware of the problem and has given instructions for a procedure to correct it in most cases. Hope that helps.

My 2007 GMC YukonXL is also using oil. It has been a problem since around 40,000miles. They have done the oil consumption test, changed the heads, etc. I am now at 70,000miles. I took it back today with still no sign of them fixing the problem. I WAS TOLD THEY WOULD DO OIL CHANGE AND ADD ENGINE CLEANER! IT WAS 1 1/2 QUARTS LOW AFTER ONLY 3000 MILES! I am very disappointed with GM products at this point. I know of at least 5-6more(2007Suburban or Yukons) in my small town alone with the same problem. WHY HASN'T GMC CORRECTED THE PROBLEM!

I have also been to my dealer at least 5 times for this problem. Yes, there is a bulletin on the oil consumption issue! I have had a head gasket replaced, rocker arms replaced, valve covers replaced, and lifters replaced and it is CURRENTLY at the dealer for replacing the rings and the pistons. I WANT A COMPLETELY NEW ENGINE! Illinois does have a "Lemon Law"! I feel my engine has been "molested" enough. Something to do with the production date and the sharing of Chevy Sbrbn motors on that day. The Chevy dealer is replacing complete engines left and right and a handful of Yukons got the bad motors. My service mgr. said that my problem has gone the furthest that he has seen for our dealership. I LOVE my truck and don't want to get rid of it. It has just 36K on it. I am very disappointed. Hoping this doesn't taint the engine for the future, all this "tinkering" to find a problem that GM doesn't quite know how to fix!

I too have a 2007 Yukon XL that burns oil excessively. I first reported the problem to the dealer lAugust 2009 and had been told for months that they were waiting for GM to come up with a "FIX!" I kept a log and I was adding 1 to 2 quarts about every 2000 miles or so. About 3 weeks ago, my truck started to idle rough and then the stabilitrak warning message would come on and the transmission would jolt as if I popped a clutch while reving the engine (even though I have an automatic). When I took it in, they replaced pistons, rings, seals and gaskets and told me this still did not address the oil consumption problem. What is going on??? If this didn't fix the problem, then there must be an engine block defect. I too think they should put a new engine in as it was a huge investment to buy the Yukon XL and I am concerned that with tearing th eengine apart and tinkering that something else will go wrong. If they want to keep future business, they need to remember the custoimer is always right and in this economy, they better treat the customer like royalty! Has anyone gone to the BB or some other agency to get a resolution?

If it is a re-occurring problem with that model, the manufacturer needs to be involved in the fix. Your local dealership will give you access to a factory service rep at your request. They have warranty power over and above what would normally be acceptable. They have acceptable oil consumption guidlines, because it will vary slightly from car to car, but if your problem is prevailant with others that own the same model, there is a design issue that should be addressed. If the oil is being burned, it has to either be blowing by your pistons or coming from the valve guides. Squeak to your dealer, the squeaky wheel gets the grease!!! Good Luck. Hope this is helpful!

I have a 2007 Yukon XL with 145,000 miles on it that burns oil as well. It has done so since it was new. I am told that it is the Valve-train on the cylinders that shut down during operating to save fuel. If I use Mobile 1 Oil like the owners manual recommends it will run for about 3500 miles before it needs a quart. If I use any other brand it will need a quart around 2400 miles. Since I run them about 250,000 miles, and in no mood to spend another $ 55,000.00 without achieving this kind of return on my investment I have decided to let it run. I've had five of them, and the 2007 is by far the nicest and seems to be holding up cosmetically better than any of the others. Having this experience I will share some of the problems I have had with all of them. The trans cooler is too small, so at about 100,000 miles you need to perform an update on the cooler or your trans will run warm and need replaced around 150,000 miles. I did this one at 120,000 miles and the temp went from an average of 203 to 180 during summer weather. All of them used oil. The 07 just has the add engine oil light. ( I think ?) They all need plugs and wires at 80,000 miles. And on the 07, if you turn off the Traction control and pull something you'll take the the motor mounts out. Agrivating for sure, but I have tried Fords, Toyotas and Jeeps, and none of them will run this long and look as good for the same money. As I have stated above, mine will turn over 145,000 miles before the end of the Holiday. I have spent $ 4,300 for repairs, and should be done other than brakes, shocks, tires and maybe a water pump.

I too have a 2007 Yukon XL and it is always burning oil. I have been involved in the oil consumption test now for 8 months and GMC tells me there is nothing wrong with my car burning 2 qts of oil within 2,500-3,000 miles. This is not right. The valve covers were replaced and still issue is not resolved. My dealer said there are others with the same problem who also can't get their car fixed. I believe the cylinders are bad, but they won't allow the dealer to run the test.

GM needs to fix this problem ASAP as it is frustrating to buy such an expensive SUV to only be in the shop every 2,000 miles to add oil..

They have to changes the pistons on my now because of burning to much oil.
