I bought my car used with 88000 miles in May ...Started out with every 2000 miles I would need to add oil. Then about 1500 in about july now its progressing to about every 500 miles I will need to add a little under a quart. Its extremely annoying as I just bought this car this year 2012. Now it has engine problems and this particular problem is VERY common in Tahoes. Its a shame GM wont recall this. However I plan to exhaust every level of management up to the President of GM or Chevy. There's absolutely no reason why someone should have to pay out of pocket for repairs due to issues that were present during assembly of the car. This is a major defect and I will not pay for GM's mistake.

I just started having this problem a couple of months ago. I am about to take it to the dealer for a oil change and tire rotation. I am curious as to what he says the problem is and more importantly, how to fix it. I should not have to take 6 quarts of oil with me every time my family and I go out of town. We keep this Tahoe serviced on a regular basis, so I am very concerned about this issue. I would say I would trade it in for a Ford product, but I have a 2010 F-150 with transmission problems. So much for buying American made automobiles!

About 8 months ago I had the oil changed at a local quick lube. About a month or two later my wife called and said there was some kind of warning light on... something about oil. After adding 2 quarts I blamed it on the quick lube guys. I normally change my oil, always have, but I won a coupon at a raffle. We were getting ready for a short trip, recently and I gave the Tahoe engine bay a once over. A feel good thing. A quart low. I blamed that on myself. Wrong. Checked the oil the other day..... A quart low.

I E-Mailed GM and complained. At 98000 miles I'm just barely under warranty. The GM rep called and I got a voice mail saying that I have a reference number and that the service bulletin says that it is "normal" for the Tahoe to use 1 quart every 2000 miles. GM recommends every 75000 miles. I change mine at 5000 miles.... SO They, GM is telling me that it is normal to use 2 1/2 quarts between 5000 mile oil changes.

This is a 40,000 dollar vehicle with less than 100,000 miles and here I am in the driveway adding oil. I have been an auto and industrial mechanic ALL my life and the only car I EVER owned that used this much oil was a worn out '51 FORD. Did I here class action law suit some were??

Noticed at around 40,000 miles, my tahoe was using excessive oil! What? This is basically a new vehicle. May have started b/f then but I didn't notice and they didn't mention it when I had my oil changed. I shouldn't have to carry a case of oil around in a new vehicle. But this is normal? I don't think so!! This isn't my first vehicle... I've never had this problem. Had a Land Rover Discovery b/f this Tahoe and at 135,000 miles never had an engine problem... NEVER was low of oil!! GM needs a recall but they'll never own up to this problem b/c it would be too expensive to fix! It will cost them in the long run though because we will purchase more vehicles in the future and if something isn't recalled on this, it won't be a chevrolet!!!

I own a Chevy Tahoe. It is suppose to be the reliable family car. I am so angry over this oil consumtion problem that I cannot stand it. My Tahoe was a $40,000. investment and to think that I have to stop in to get the oil topped off every 1000m is pain in the butt. My Tahoe is currently in the service center as we speak and they say there is nothing wrong with it. It just has a hot burning engine and it is no problem to come in and top it off. My customer service gentlemen is at least being fair with us in regaurds to our Tahoe. He thinks the oil consumption issue is a real problem too. Butt I am getting all his promises in writing and have a wittness everytime we talk about the engine issues.

My biggest problem is that I do errands in town and do not drive great distances to often. So for me to come in every 1000m is going to take a while. I was promised that if I follow the oil consumption test to T, and never mess it up that my Tahoe will be taken care of long after warranties have run out. I am not suppose to have any cost out of pocket while dealing with this oil consumption testing.

I think GM needs to step up to the plate and recall this V8 5.3L engine!!!!!!!!!!!

this truck uses 1.5 -2.0 qts of oil every 1000-1500 miles? GM says this is normal?? my local dealer ankeny iowa.... tells us to call the 1 800-chevy usa .. they cant call me back for 4 more days .. sometime between 1-3pm on friday the 25th .. when did the cable company start running general motors? we have had both synthetic and conventional oil in it and makes no difference. over 1 yrs of oil consumption analysis and all i get is just keep your eye on it . how is that even acceptable! this truck only has 22k on it now and getting worse. Its not hard to guess why gm is broke. junk cars and crappy management!!!!!
