I can't believe that the 07 Suburban oil consumption problem hasn't been mentioned on this site, it is everywhere else. Many 07 Suburbans burn a lot of oil - GM will try to tell you that a quart every 1500 - 2000 is normal - which is just ridiculous. If you burn a quart every 1000 as mine did they will repair it (if you are under 100,000 miles). It's a big repair, major engine rebuild. In mine, there was a lot of valve train damage, so it's not just that the engine burns oil, it is slowly eating itself. It is a huge amount of work to get Gm to admit to this problem and fix it - I think they hoped I would just give up and let them off the hook.

Burning 2 qts of oil every 3000 miles.....no leaks...no smoke from the exhaust. Lots of reports of this posted by lots of owners. Obviously a big problem the GM. Has not addressed.

I am burning a quart every 1000 miles. And I get a fog of smoke when we start the Suburban that looks horrible.

It's burning oil excessively. My check engine oil level light comes on a lot. I get my oil changed every 3000 miles but before that 3000 Miles is up the check engine oil level is on. It's a lot of miles on my truck but I keep it up to date I have put at least $2,000 worth back into the engine and cooling system but it still runs good besides the oil consumption

Engine will start running sluggish. Check the oil and have to add at least one if not two quarts of oil. Haven't taken it to a dealer yet but have heard of this issue on other GM/Chevy products with the same engine.

Quickly Burns oil

Been complaining for a year or two. Dealer acts if if they don't know if this issue. Now their telling me new rings and Pistons. I think it's bs I've always kept up maintenance on vehicle. I'm sure they knew when they sold me the vehicle now they expect me to pay them $3300 to address a problem I've complained about for ever.

Our Suburban starting burning oil at around 60,000 miles...several quarts between oil changes. The dealer required multiple oil consumption tests and offered several short term fixes up through our warranty at 106,000 miles, but did not want to rebuild the engine as it should have done (they said GM will only approve a complete rebuild after all other repair options have been exhausted). The dealer admitted to us that this condition is a known defect in the engine, GM is aware of it, and that they have a number of people with the same problem. We have a long history of these problems documented in our service record and are now again experiencing oil consumption problems starting at approximately 120,000 miles.

Due to our long service record of oil consumption problems, I hope that GM steps up to the plate and properly takes care of the repair at no cost to us, but we are prepared to fight them. My advice, if at all possible, is to get them to rebuild the engine while under warranty.

New Rings and Lifters needed. GM offered to pay 40%. Still feel hosed. A vehicle this expensive with only 80,000 miles should not need serious engine repair.


Some models are effected from carbon build up around the rings causing them to stick. There is a procedure to correct this and if it doesn't help, I have put several sets of pistons in w/ new rings.

1quart consumed every 600 miles, then low oil press go/off, then Trac contro warning. Started knocking no reason. Dealer can't figure?

2005 Chevrolet Suburban 1500 - 5.7L V8 214,000 mi,
I have this issue in my suburban,i change my oil every other month,i have no leaks but I see white smoke during start up at times especially when its warm outside,its a common chevy problem I hear its because people went from using flex fuel to reg and the flex fuel alcohol burns up the rings, I use lucas and nosmoke during all of my oil changes so it is what it is,fyi my husband has a 05 which had the engine replaced and no burning oil issues,,go figure

2007 Chevrolet Suburban 1500 - 5.7L V8 49,000 mi,
Have contacted the dealer and they are to get back with me. I have checked on line and this is a common problem it seems. I have regular service, purchased new, now have 53,000 miles. No leaks and no smoke but I was told that the catalytic converter will take care of smoke until it clogs. Have purchased several cars from same dealer so will wait and see what happens. I am guessing it uses one quart every 1500 miles. Until 49,000 miles, I never had to add oil. Lincoln is looking better but I still remember the problems with their 1948 Continental V12 (awful engine) which I changed to a Cadillac V8 and I still have. The Suburban LTZ has been perfect except for this.

Change oil every 3000 miles and have to add 1.5 to 2 quarts between oil changes

My suburban burns oil ever since I got it. I have to make sure to fill again before the next oil change at least once. Someone said that it burns hot?! I've had to do this since owning for two years.

Waaaaayyy too much oil used.

2012 Chevrolet Suburban 1500 - 5.7L V8 197,000 mi,
the vehicle is consuming 3 quarts of oil in 3 months

Engine oil is consumed as soon as I get an oil change. Have to add 5 QT every few weeks.

2011 Chevrolet Suburban 1500 - 5.7L V8 95,000 mi,
Not fixed and researching new issue of burning excessive oil.
