#61 of 92 2006 Impala SS oil consumption
Feb 22, 2012 (9:05 am)
We have a 2006 Impala SS, we bought it new and it it using 1 qt every 1000 miles, told the dealer and there answer was it is acceptable to Chevy to use this amount of oil in this engine, GM wil do nothing about it, but I have owned Chevy all my life and am serously thinking about buying Kia or ford, I have been told that the oil is getting burned up in the catalytic converters and this is why you dont see the smoke , and there are no leaks anywhere, If someone has an answer as to how to remedy this with GM or what to do, I would really appreciate it,

My 2008 had the same problem (see earlier posts). Finally they agreed to replace gaskets where they claimed they found "small" oil leaks - this after 6 months of an oil consumption test. I don't have the invoice handy now to identify exactly what they did but I mentioned all the work done in an earlier post within the past week. If you can't find the post, let me know and I can reply again with more info. Dealer had told me the same thing - the GM line is that a quart per 1000 miles was "acceptable". I raised the roof because that wasn't acceptable to me at all. I have to believe they found it when they added a dye to the oil when they changed it once (part of the consumption test) then scoped it with a black light after 500 miles or something like that. It took another problem for them to fix both the oil issue and the other issue that came up - the gasket replacement was covered by factory warranty, and the rest by an extended warranty. Good luck ... I know what a hassle you are experiencing.

Too much BS going on ! My 2008 Impala will suck the oil pan dry long before its due for a oil change. Same story taking car in for 20 min sit & wait, to check oil every 500 miles. The wife drives it to work 80 expressway miles round trip a day, plus her other shopping so almost 100 miles a day. Its sitting at the dealer day 2 now for another check engine light on. I found a Chevrolet Customer Relations Department # 800-222-1020 the lady was nice and said they will call the dealer today she even gave me a case # a phone# ext# as I told her, I will make signs of my car drinking out the hood with a baby bottle of oil, put them on the both sides front & rear and park it in front of every chevy dealer in town, I will make a unhappy chevy owner picket sign and have some of the internet emails to show interrest people thinking of buying a chevy! with chevy saying using 1 quart of oil every 1000 or 2000 miles is OK ! It dont leak a drop of oil, its not in the cooling system, so its burning it ! even if no sign of smoke !

Good afternoon oileatingchevy,
I'm happy to hear you've been in touch with our Customer Assistance Center - do you have a case number (71-**********)? I would be happy to check in on it to see if there are any updates for you.
It is correct that the accepted rate of oil consumption in passenger vehicles is 0.946 liter (1 qt) in 3200 km (2000 mi). All engines require oil to lubricate and protect the load bearing and internal moving parts from wear including cylinder walls, pistons and piston rings. When a piston moves down its cylinder, a thin film of oil is left on the cylinder wall. During the combustion process, part of this oil layer is consumed. As a result, varying rates of oil consumption are accepted as normal in all engines.
Other factors can affect oil consumption, including continuous driving at high speeds/high RPMs may increase oil consumption (because this may not always be an everyday occurrence, it is hard to determine exactly how much the oil economy will be affected) and engine wear (piston scuffing, excessive piston-to-wall clearance, tapered or out of round cylinders, worn, damaged or improperly installed valve guides, seals and piston rings will all cause an increase in oil consumption).
Again, I'm happy to check into your case if you wanted to get that number to me!

Like I told Gm Customer Service , I made signs w/ pictures of my car drinking oil, a picket sign that said UNHAPPY CHEVY OWNER ! I parked it in front of 4 Chevy dealer lots, only took 5 mins for them to come out and talk to me. They were all nice to me except one , who called the cops on me, but its not against the law to picket, just keep moving, be nice, dont block people or cars ! He later came around to my way of thinking and said he will make some phone calls and try to help. I gave them all the case # names ect. only took 15 - 20 mins at each place. One of the Bigger Chevy dealers said they already fixed a car with the same problem before, and would gladly check into it, make some calls and call him back Monday morning, ended up taking the car there at 11:00 he gave the wife a 2012 loaner car. Car was ready next morning they did the heads, and also found the intake manifold gasket was leaking but not on the ground, they found it with mirrors. We bought 3 new chevys from our small town Chevy dealer in 2009, where we buy our next car ?

I want to buy a new 2014 Impala as soon as they come out. New one really great looking but I don't trust that 3.6 engine. After reading about it in the Cadillac and its been out a few years and do they try to change for the better or do they just keep building the way it is. I have a 2009 Impala LTZ with the 3.9 and its a great car. Change oil 3-4000 and dealer always checks before change and its always full. Thats bs that a quart to 700-900 is normal. I had over 65 cars in my life time and the most oil I had one burn was a quart to 1200-1500. I would like hear from someone who has 2012 with 3.6 or other GM with that engine. I've read most of the Cadillac complaints. I can't believe GM would keep building that bad of engine and not improve it and not take care of the customers who have already purchased them.

I also have the 3.9 V6 in a 2007 Uplander. It has 66k miles and does not use any oil between oil changes. I use Mobil1 and change the oil every 3k miles. A quart or two every 1k or 2k miles is ridiculous for a new car, especially a luxury car like a Cadillac. I agree with you, stay away from the 3.6. It's a poorly designed and engineered engine. Good luck with your next purchase.
#69 of 92 oil consumption/ 2008 Impala
May 29, 2012 (5:42 am)
We bought a 2008 Chevy Impala last spring from a dealership. The car only had about 23,000 miles, excellent condition inside and out. We noticed when checking the oil it was barely reading on the stick,so called dealership and they did not say much about it and changed the oil again. Then, it was very low again on stick and first thought " It's using oil because it was not leaking oil . Then, the dealership sent us to the Chevy dealership and they replaced a seal ,said it was a small leak . Then, it is still reading about 1 notch on stick and we are upset about this whole situation. Should this be considered a lemon car and pursue under the lemon law act ? It is still under warranty but we do not want this car because we know it will be nothing but continued problems . Please give us any feedback on this.

My 2008 went thru that for about 6+ months, with trips to the dealership every 500 miles for a consumption test (they checked the oil). Finally after another idiot light showed up (check engine) they kept it for a day checking it forward and backward. They found at least 3 "small" leaks, which took them 3 days to fix. It was all done under warranty but it was the idea that they kept telling me there was nothing wrong before they had to chase down the check engine light. Even told me the loss of oil was within toleration by the factory. So far their fixes seem to have done the trick. I even get better gas mileage if my last road trip is any indication. I've entered several posts here related to the on-going issue from months past. Search my id and you should get a feel for what I went thru. Keep at them and don't take their glib excuses; demand better service than that! I love the car but was very very disappointed in how they handled my questions and complaints. Good luck! ID=onemorebob
