Question about 2007 GMC Yukon

2007 GMC Yukon using a quart of Oil every 2000 - 3000 miles

I have been getting a message "engine oil low /add engine oil". I have 70k miles and this started around 60K miles. This is the second time it has happened. No oil spots in the driveway. I get the car serviced at the GM dealer every 5K. The dealer is telling me using a quart of oil every 1K miles is within specs. I have never heard of a car with this low mileage using 1 -2 qts between oil changes.
Is there a known problem with this engine using oil? With all the other problems with this car, I cannot see myself buying another GMC.

Sounds funny, I would take it to an indepened repair shop and have them check it out, we have many customer's with Yukon and have not heard of that, I have a GMC with over 315,000 miles and between oil changes, maybe a qts low, have it check else where.

I have a 2007 gmc Yukon denali with the 6.2l in the last month it has randomly puffed a bit of smoke on start up what might be wrong only 120k on it

Hi Bryce, For the miles and engine in your vehicle, a bit of visible smoke from the tailpipe on cold start is normal. It indicates a small amount of engine oil is leaking past the "valve-guide seals" in the cylinder head. For now, I wouldn't let it concern you too much because it's actually a VERY small amount of oil making its way into the combustion chamber while you're snoozing.

It only takes a drop or three to produce a huge amount of visible smoke when it burns, and it probably won't even leave deposits on your spark plugs at this point.

This condition isn't harming anything except your nerves, and it won't cause a breakdown or leave you stranded. The oil lost (per mile) is too small to result in the need to check the dipstick more often, but you should get a sense of the loss-rate by periodic checks over a given number of miles.

Top off your oil, and check it every two or three fill-ups, and, my guess is, you won't have to add a quart before driving 1000-1500 miles, which is nothing to worry over, but determine how many miles it takes to use a quart, so you know when to add.

If you want to narrow it down, pop the plugs out and check for any light colored deposits, and note the particular cylinder from which a contaminated plug was removed. You'll probably see little, if any, deposits for now.

Oh, and there are NO magic snake-oil remedies, despite fancy promises on the labels of opportunistic, quick-fix makers. Don't fall for their distractions. The best you can do is to keep up on your oil maintenance. Running dirty oil causes accelerated seal wear.

Happy Motoring!!!

Oil say 36 percent use what does that mean

36% means only that much of it's life is left.

If you vehicle is low on oil it will say check oil. To do so you need to open the hood and use the dipstick to do so.

Also if your ol life is only 36% that usually means you have driven 6000 miles since your last oil change............ I suggest every 3000 miles.

Impala low engine oil pressure

Could be oil pooling in the valve cover caused by a partial blockage of the drain gallery, but you'd almost certainly get a oil low message too. I assume the oil and filter is changed regularly? You could try adding Marvel Mystery Oil, about 12oz for about a hundred miles and then change the oil and filter. Depending on your level of adventurism, you could drain the oil and replace it with new oil, except add a quart of automatic transmission fluid in place of one quart of oil. Some people say ATF is bad for seals, some people use ATF to rejuvenate leaking seals. I don't know who to believe. Run that for 100 miles and change the oil and filter. I've even seen someone replace their oil with kerosene and a quart of oil and run it at idle for 5 minutes, then change the oil and filter. Instantly freed 2 stuck lifters and the engine was fine.

Best bet would be to run the Marvel Mystery Oil first. Then, if the problem persists, either change the pressure sensor and see where that gets you or go for the ATF in the oil trick.

Low oil pressure/ guage fluxuates but runs low

Sounds like a valve lifter or in queens english a hydraulic tappet ,Now what i used to do on the rover V8 was to add a tin of gunk brand name exterior engine cleaner and then let customer have the car back and do some miles,or as soon as the noise stopped ,then change the oil and filter and add the diesel/petrol turbo engine oil as this is detergent and then change the oil every 5/6000 miles with a oil filter every third oil change ,if no engine cleaner then try half a litre of diesel or just change the oil for one detergent type diesel engine oil you will not hurt the engine using this oil the cheaper it is the better as well .In extreme cases i give a 2 second squirt of fairy washing up liquid to the oil as well ,has to be fairy mind them cheapos are no good for this job .Stop worring about it and just do as i say

It is normal to use over a quart of oil before oil change

My 1993 voyager is like that. It may burn some , it definitely leaks some , and it could be just sending some through the PCV valve. Oil leaks and burning oil causes pollution . If you can fix it with a new seal or a valve cover gasket it is easier than constantly checking your oil. Temperature, trailering, speed, outdoor temperature, and engine RPM all can be factors if you are losing oil. If your engine is a quart down, the engine oil consumption rate doubles or triples. In other words the lower the oil level the faster it disappears. High mile cars will drive for years as long as you add oil when it is needed (keep the oil level between the marks). Fix any obvious leaks. Then determine your oil change interval (3000 miles, 4000 miles, 5000 miles). I change between 4000 and 5000 miles. If i am a quart low at 3500 I add a quart. If I am a quart low at 4500 miles I just change the oil in the car. A good practice is to carry a quart of oil in your vehicle just in case you need it. It is far cheaper to add a quart when needed than to go to the dealer once to maybe fix a problem that they may not be able to find or fix. Older engines (even some newer ones) just use oil , especially in hotter climates. Fix the obvious and carry a quart.

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...

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.
