    I am having my 2010 yukonxl with 93k miles in for the piston and ring replacement. Went through a few oil consumptions and there was a problem. Will check back once I get this done.
    Are there any engines that do not use oil? The dealership was business like but showed some attention to me . Do you think this will fix the problem or am I better off dumping it and buying a F150 King Ranch

    Hi vayukon,

    Please keep us posted on your dealership visit. We're sorry that you've had to return for service, but we hope that your dealer is able to resolve this matter for you. If you have any additional questions or inquiries during this time, please do not hesitate to send us a message.

    I just finished my last consumption test on my 2008 yukon which has about 83,645 miles, its seems that I will need to have my car engine taken apart and possibly have my pistons replaced. The gmc repair shop has just stated that since vehicle is no longer under warranty and its been 425 days since warranty expired, gmc will only cover 45% of repair cost and I will need to come up with 55% of the remaining cost. This yukon has burnt oil and I really do not feel that this is fair to me the owner for a "defect" according to me. This seems to be a very common problem with Gmc yukon apart from other issues with the locks and windows on my car. I feel cheated that this vehicle is not fully covered as stated 100,000 miles . I dont have 55% percent to cough up.

    We have a 2007 Yukon Denali XL and are also experiencing a host of issues, along with high oil consumption. Our issue is that our local dealership keeps wanting to charge us a diagnostic fee for each issue, which would be nearly $800. In addition to the high oil consumption we have a host of electrical problems and transmission problems.
    When we purchased the vehicle it was in the dealership 13 times in the first few months for problems. Our dealership told us they'd find us another vehicle (we purchased Certified GM Used) and they never followed through. We had nearly 100 calls to them for updates and they told us our vehicle was "too rare" and he had his guy searching 13 states. We have a white Yukon Denali XL. We see about 4 per day where we live. Not so "rare". We're so disappointed. We purchased this vehicle to tow our travel trailer and take trips with our family. Unfortunately, we haven't been able to tow for nearly 2 years due to all the issues that the dealership can't seem to fix. They just want to "guess" at the repairs and hope it works, meanwhile charging us astronomical amounts of money. So bummed.

    I too have this oil consumption issue with my 2009 Yukon SLT with 52,000 miles. I first discovered the issue in the upper 30K mile range when it suddenly lost considerable power. I later discovered that the oil was being consumed by the engine after the dashboard light came on. The dealership service center required that I go through the oil consumption test whereby they determined it was consuming about 3/4 quart per thousand miles. They then agreed to replace the oil deflector per the service bulletin, stating that it should resolve the issue. Now, at 52K miles the vehicle appears to be consuming much more oil, approximately 1 quart per 1200 miles by my estimation. Aside from that, it appears that the dashboard light no longer illuminates to warn of low oil level/pressure. I returned to the dealer today with 4 months left on my warranty, and of course they want to go through the oil consumption test again. GM is obviously aware of this issue with the AFM engine and they are aware that the only complete solution is to replace the engine. I feel that at best they will only replace the rings, lifters and pistons which is only a temporary fix that addresses the negative affects of the problem, not the problem itself. I am dumbfounded by their claim that 1 quart of oil consumption per 2000 miles is normal. Would GM make this claim if oil was leaking onto the ground instead of internally? If this is "normal" then what is the point of having the oil changed as it will continually be topped off with fresh oil? If this is "normal" then GM should be required to disclose this information up front and list the "oil economy" figure along with the fuel economy figure.

    Given the number of cases I have found simply by looking through various forums online, I am surprised that there is not yet a class action lawsuit filed against GM for this issue. [non-permissible content removed].
    Thank you

  • I have a 2009 Yukon XL with 92310 Miles and with 40% left til Oil needs changing. the dipstick is dry. Sent it to dealership for Oil Change and Oil Comsumption test.
  • Wow! I knew a lot of people have these issues but not this many. We have a 2009 GMC Yukon XL with 76,000 miles. We had the oil consumption issues (and issues related to it like noisy lifters) going way back and the same "we would have to do the test" or it's not that far from "normal" consumption comments from the dealer for years.

    Well, it all came to a head last week when the Yukon started smoking on startup last week and we took it in to the dealership yet again. This time it was definitely time for serious action. Pistons, Rings, Valve cover, Oil Deflectors, Lifters, etc. $4,100.

    "But I'm sorry you are out of warranty by 20 days." "GM will help however and cover all but $1,000 of the repairs."

    No, I'm sorry. That is not fair. If I would have brought it in three weeks earlier everything would have been covered. This is a pattern failure folks. GM has been aware of this for years. Their own TSB has been revised 5 or 6 times already (now TSB# 10-06-01-008G). They knew of the issues with my vehicle and documented it over the years.

    We have always owned GM vehicles. 2 Chevy Blazers, 2 Tahoes, 3 Suburbans, 1 Yukon denali and this Yukon XL, etc. We have been happy with them in the past but their refusal to pay this entire repair is unacceptable and really makes you think twice about ever going GM again.

    Not fair?

    You have a six year old car with 76,000 miles and you can get a total engine overhaul for 1000.00??

    I must be missing something here.
  • A friend of ours had a 2008 GMC Yukon and had started having the high oil consumption problem. They took their vehicle to the dealer and were told it was their engine. The dealer told them it was because of the engine switching from V8 mode to V4 mode. They told them it was a bad design and when the engine would go to V4 mode it was causing problems with the other 4 cylinders that were not being used. Not sure how that whole thing works but they told them this was the problem and the only way to fix it was to replace the engine. They bought a new vehicle instead. I own a 2007 Yukon and was hoping this wouldn't be a problem. Well I have 119,000 miles on it and have put 2 quarts of oil in it now in the last 2 weeks.

    My question is if the GMC dealers know this is a problem why hasn't there been anything done about it?

    What oil have you been using in your truck? Be very specific.
  • I usually use Valvoline Max Life 5W30 for high mileage.

    You car when originally built required a 5W30 motor oil that met API SM, ILSAC GF4 AND was approved to meet GM spec6094M which was obsoleted in 2010 and replaced with the dexos specification. This isn't saying there is anything necessarily wrong with the product that you are using, but it doesn't meet the specs and requirements for your engine. To get GM's 6094M specification approval an oil had to resist producing piston ring land deposits, (a likely cause of the oil consumption problem that you now face) and be much thinner at cold temperatures than an oil that only met the API and ILSAC specs. ( FYI There was in fact more to it than just those two requirements) There are many people who are in the same position that you are, your engine oil consumption problem are most likely the result of using products that failed to meet the manufacturers specs.

    This very issue was made worse by articles that served to confuse the issue and make it appear that anything that had API and ILSAC approvals was an equivalent product to what GM required. API and ILSAC were (and still are) only a minimal standard that fall short of a lot of manufacturers specs.

    Follow this story and read the comments to see where a lot of the confusion came from.

  • I have a 2007 GMC Yukon with the same issue ! I bought it used with 110,000 miles and now I know why they got rid of it ! On a recent trip to Florida used 3 quarts of Oil. NOT happy ! I love the truck , I have always bought GM cars and trucks. GM needs to recall these trucks and make this Right !
  • I just checked to be sure ! Using Pennzoil 5x30 with the GM 6094m rating !
  • thecardoc3thecardoc3 Posts: 3,613
    That spec is obsolete now, you should be using a dexos approved product. However, the problem is already present. Was the previous owner using the right product for the entire time?
  • It should say that on the Oil filler cap ! not just "5x30". "Use Dexos approved oil only". When they realized there was an issue, they should have recalled the trucks and changed the cap and put stickers under the hood letting people know ! But that would be acknowledging that they found a issue! Many of these trucks are 1 owner trucks.Mine is not. But I bet if people knew, there would be a lot less of this.

    It should have a picture of the owners manual on the cap too which meant check the information in the manual, but that apparently was too subtle for people to notice.

    There were issues all right, but it wasn't with the truck or the oil cap labeling. Just look at articles here and you will see how much pressure was put towards shouting down the oil specifications, especially when it came to GM switching to the dexos standard. (which made the 6094M and 4718M specs obsolete)

    The arguments "against" the new specifications by certain parties relied on misinformation between what is a specification, versus what is a brand. It was no accident on their part that they played that game, IMO. That led to no shortage of "expert consumer" advice which discouraged the use of products that truly met the specifications. Do some research, and you will see the misuse of the Magnuson Moss act which blurred the lines as to what was really "equivalent". There were some "experts" that went as far as to attack shops who followed the manufacturers recommendations claiming price gouging on basic services. That served to encourage consumers to go to cheaper alternatives, which meant in all likelihood that their cars were (and may still be getting) serviced with products that fail to meet their vehicle's specifications.


    Many of these trucks are 1 owner trucks.Mine is not. But I bet if people knew, there would be a lot less of this.

    I wish that was true, but the effort to try and educate the consumer was rewarded with accusations of greed while ignorance of the changes in the specifications was lauded as being in favor of the consumer because it allowed for cheaper prices. Just do a little searching and watch it play out even inside of this forum, in fact this very thread.
  • Anybody tried anything like Marvell Mystery Oil or anything to clean up the oil control ring gland ? Just wondering ? Or are the Oil control rings worn out ?
  • Mr_ShiftrightMr_Shiftright CaliforniaPosts: 52,732
    The only sure way to test for ring wear is a Cylinder Leakdown Test. I suppose Marvel Mystery Oil, being mostly mineral oil and white spirit, could clean up some sludge---if that was your problem--although sludge that bad probably needs a more serious intervention than magic in a can.

  • I never used Marvell Mystery oil myself but I have friends who swear by it. Just wondering. Magic in a can ! Love it !

    Well now this oil consumption issue has turned into a emissions issue ! Now I got an emissions / check engine light in. It seems the burning oil has trashed my catalytic converters. Replacing the cats will only temporarily fix my truck.So now I have to get the oil control rings replaced, then the y pipe/ cats .! Thing of dumping this truck !

    I have an '08 Yukon Denali 6.2 with only 58,000 miles. When I tow my boat, I use 1 quart of oil for every 200 miles. Not 2000...200. When not towing, I use a quart of oil every 2500 miles. And this is AFTER having the suppposed ill-designed valve cover replaced. I don't think this oil consumption issue is about oil specs or valve cover deflectors. GM built these engines for gas mileage and the short-skirted pistons/rings simply fit "loose" in the cylinders, partly to allow for AFM. Mine exhibits piston slap for the first 10 minutes of operation. When not towning during the winter, the engine totally carbons up due to the oil burning and when I start pulling my boat in the spring, the check engine light comes on as the carbon is being blasted out of the engine, setting off the exhaust sensor. Instead of owning up to the issue for long-term goodwill, they force owners to go through "oil consumption tests"and jump through other hoops until they give up or force them into submission to pay for rings/pistons or full engine replacements. This is just one step down from VW's diesel emission scandal as far as putting one over on customers. When I replace this thing, it will be a Ford.

    2500 miles per quart is well within specs but 200 miles per quart is nuts! I have to wonder just how big your boat is and how much it weighs? I mean towing is tough on any car or truck but this makes no sense UNLESS that poor truck is REALLY stressed by tremendous weight.

    Fords can use oil too BTW.

    The quart in 2500 miles is well within the requirements. However, I assume that should also apply when towing as long as that weight is within the tow capacity for the rig. What is the powertrain warranty on your truck? 10 years/100k miles?

    I'd see the dealer and let them do a use test with your boat in tow.
