GMC Yukon XL Normal Oil Usage?

    Thanks but after the shenanigans at the dealer and all the problems everyone is having with their engines in about every GM forum I decided to trade in the "normal" Yukon. When I asked the service manager about the overservicing of my vehicle he told me that I checked the oil wrong. He states, "You cannot check the oil when it has sat for an hour....due to the oil passages being so this point I shut down. He suggested I run the truck to operatinb temp and then wait 15 minutes. Wouldn't you know it was the same level! Go figure. I then asked him what overservicing a vehicle could do to the engine. He states "No problem. These engines can operate with one qt of oil extra just fine without any problems." He even stated, "They are built to tight tolerances?" Really?? I almost thought I was talking to a janitor.

    I guess that is why there is a big bold statement to the effect of "operating an engine with too much or too little oil can cause damage......" in the Operators Manual. The more I think about it they probably put thicker oil in there as well to skew the test even more.

    It is because of the dealership and the numerous problems across the web concerning oil consumption problems that I traded my Yukon XL in for a 2012 Ford Expedition EL.

    I guess I gave my "normal" oil consumption vehicle to someone else. I feel GM knows there is a problem and they are trying to band aid fix these vehicles; coupled with my local service department trying to "play me" it was time to say bye to the GM brand for good. To make matters worse I now have learned that there are a few others that have had the overservice trick done to them at the beginning of this "oil consumption" test. If anyone gets one thing out of this...CHECK YOUR OIL LEVEL BEFORE YOU LEAVE AND MARK IT (a small scratch works well) AND LET THE SERVICE MANAGER KNOW AND WITNESS IT. MIGHT EVEN WANT TO START NEW AT ANOTHER SERVICE DEPARTMENT.

    From a once loyal 30 year hardcore GM a new Ford owner.


    BTW. As far as the door actuators as posted previously by another member: I replaced three separate door lock actuators and the last one was out when I traded the vehicle in. Also, the side body molding warps rather easily and starts to curl up and eventually starts debonding and cannot be fixed. It is a buy new, paint and replace item.

    LASTLY. If anyone lives in the Fort Worth area avoid the GMC Service Department in Grapevine, TX.
  • Wow... glad I did a search on this problem. I am going through the same issue on my Yukon XL 07. I have been to the dealer once per month for the last 5-6 months over the oil light. What a nightmare. Got the 'ol run the consumption test, then put the deflector plate on it.. had to pay the $200 deductable for my extended insurance, then pow... 3 weeks later there is that light again. Called the dealer tonight and said bring it in tomorrow. Service mgr was obviously exasperated. Reality is that there is a known problem, the methods to remedy arent fixing the problem and GM knows it.

    Sarah, how can I get this really fixed?

    plsfixmyyukon, I would try to get your $200 back. If your vehicle has under 100K of miles there should not be a charge for the drive train. If it is over 100K miles then GM wont cover anyways. It is a shame that we have all had to go through this. It took me 30-40 trips to the dealer with all the fixes they tried, they could have just put a new engine in and it would have been less expensive. I has the PVC replaced, clean the valve covers with a new deflector plate, then it was clean the valley, then replace the both heads, then after that replaced the Pistons, Rings, Rods and bearings. Hey finally it does not use but about 1qt every oil change which is about normal. Now I do not understand why this is a known issue and they require a good longer term GM buyer to waste so many trips in and use their gas and there time to fix something that would be so easy to just bring it in for one oil consumption test then if it fails, replace the engine.

    I find it funny that GM actually told me that they could not be certain that if the engine was replaced that it would stop the oil usage issue. So funny. I guess they have no confidence in their engine department to make a good engine that does not use oil. Seems a little strange. GM is just waiting this out to get all these vehicle over 100 miles or 5 years which is this year (2012) then they will not have to worry about it.

    I figure with all the extra oil I had to use and my time that I wasted coming in to the dealership, I spent about $5-7 K of my own money and lost time because of this issue. I wonder if a class action suit would get the engines replaced and quit wasting the GM customers time. But then the government owns them so what does it matter.

    I just hope everybody that reads this realizes you can make a difference in the future. I know I will...I will NEVER buy another GM product as long as I'm alive. My MANY years of driving Suburbans (Yukon XL, Yukon, Tahoes, etc.) since 1972 (often had 2 at a time...sort of the his/hers OVER! The USA should have NEVER bailed out ANY of the car companies!

    I'm sorry to hear about the drawn-out repair process you have been through; I'm sure that that wasn't convenient and got frustrating for you. It looks as though after all of the work that has gone in to your Yukon that the oil consumption concern you had had was resolved? How is everything running?

    Wow, why did I think maybe just maybe my 2007 Tahoe with 46,000 miles would not start to use oil like all these other people are going through. Well it has now I guess I will have to fight with Gm to get this problem fixed. This is just going to be a big hassle and a big waste of time.

  • Recently, my 2008 Yukon 5.3L (with 79,000 miles) began misfiring, and "service traction control" and "service stabilitrak" popped up on dash. I immediately limped over to my dealer. The car was definitely misfiring and shifting very hard. After 3 days (4 hours of diagnosis)???, the dealer explained that I was down 4 quarts of oil (within 3,000 miles), and claimes that they need to replace the deflector plate and de-carbonize the engine at a cost of $1,200. First of all, how is this not covered under the 100,000 mile warranty??? and how does oil consumption have anything to do with stabilitrak and traction control? I feel like I'm getting ripped off, and I'm in for a lot more headaches and wasted trips to the dealer. Can anyone shed some light on this?. Thanks.

  • My 2007 Yukon is doing the same thing. I took it and they did some work on the engine while I had just passed my manufacture warranty by one month. Good thing is that they still goodwill the job and was not charged. Great huhn? Not really because months later it still did the same thing, burned about 2 qts. in 2000 miles. Then I found out that it is a three step process in which the first two never fixes the issue until the third comes along. The change of the pistons and a little tweak here and there. Now they want me to pay half on step two. The average of this job comes to be around $6000. It will cost me $3000 to have the same issue in months this should be a recall on the engine. I have called GMC customer service but they have yet to return my call. I have two GMC vehicles and this issue is making me look into other manufactures for future purchase in cars. The sad thing is that I a only 28 years old. I have a lot of cars to purchase in my life to come. Hopefully:,)

    If it has the 5.3L V-8 you are certianly not alone. My 2008 did it after just 52,000 miles. GM refused to acknowledge any kind of problem and kept sening me back for oil changes. After i threatened legal action they replaced all pistons, connecting rods and rings. They know about the problem, they just know that the cost to correct would break them.

    I've since advised all of my colleagues and extended family to avoide GM products. We've always been only a GM family. We've purchased 3 brand new our selves and our relative have purchased many more. Venture, Aveo, Uplander, Cobalt, Saturn just in the past few years! That's over and GM can do as McCain once suggested, "Blame yourself!"
  • Since around November, I have been having this oil consumption issue and had worked done to my GMC Yukon. It has been worked on once and my next job will cost me a lot. I've talked with GMC personnel but they have been extending this issue too long. I wonder if it is to find a way to neglect paying or assisting me with this big problem and headache this oil burning issue has given me.

    They are calling me every other day to keep me up to date, but it should not be dragged this long. What should I do next? Anyone have any good advise?

    Not sure what the scope of GMC's participation is, but you could try the BBB Auto Line. Or try your local consumer protection agency or lemon lawyer. It's nice that GM went to bat for you when you took this problem to the dealer a month after the warranty expired but it doesn't sound like they fixed it.

    $3,000 would go a long way toward getting a crate engine installed.

    Add me to the long list of others with 2007 Yukon XL oil consumption problems. It started at the 30,000 mile mark and since then I have been through 3 oil consumption tests and three rounds of extension mechanical fixes per the GM specs and its still not resolved. I contacted GM customer service and was assigned a case number but all that did was put a rep on the case who called me and the dealer to monitor progress of the attempts to fix it. They declined my only request - which was to extend my warranty in light of the fact that I now have 68,000 miles on the engine and the 5 yr warranty period expires in July 2012. Its going to be tough for me to buy another GM vehicle.

    Question for the group...bought a new 2012 Yukon XL and took it to the dealer for it's first oil change. Afterwards (noticed this about a month later - my wife drives this truck) that the oil pressure jumps from 20s to 60+ when I give the truck gas. Harder throttles result in larger jumps...needle moves very quickly then goes back to the 40 range. Is this normal or has anyone else had this issue? Every car/truck I've had in the past the oil pressure never moves, regardless of RPM.
  • thecardoc3thecardoc3 Posts: 1,521
    The oil pump is directly driven by the crankshaft, so the faster the engine is runnng, the more oil is being pumped. (higher pressure) Industry guidlines typically call for approximately 10PSI per 1000 rpm. So essentially at idle, anything over 10PSI is additional capacity for the lubrication system. Keep in mind, gages like the one on your dash can have some variance in what they appear to read but your description of the gages operation sounds perfectly normal. Do be sure to always use an oil that meets the dexos1 specification oil with your truck. Your invoice shoud reflect that this is the oil that was used.

    So here I am again, 1800 miles since my oil change. Oil light is on again. We have done two of the update bulletins through GM through the service department. This has been going on for two years and 20,000 miles. I am beyond frustrated. You would think at some point in time GM would just authorize the engine to be done. I have the extended warranty through GM-that is what is the classic part! And I still can't get the engine replaced!!!

    Looks like I am not alone in having oil consumption issues with my truck! Wish I would have visited this forum before my purchase. 3rd time in for my truck. Guess they installed oil deflector and cleaned the carbon out. Hopefully this will work.
