#54 of 92 Re: 03Impala LS uses 1 quart of oil evey 3300 miles [heyphillip]

I have a 2008 50 Aniversary Impala that has the same problem I read about here. I noticed on long trips, I was using a great deal more oil than in city driving, once running nearly dry. My dealer now has me on the familair consumption test, but has already documented the heavy usage each time I return from a trip. I have even taken it to Chevy dealers in the distant city and document that they added a quart after a 350 mile trip. When asked, the dealer tells me they have never seen this problem in an Impala! From this message stream, I guess I'm not hearing the truth from them.

After I completed the consumption test, the dealer sent the information to Chev. The dealer replaced all the seals and gaskets stating that the cause was "leaking valve guilde seals. This work took several days but as they had given me a 2012 Chev to drive, it was not a problem for me.
I also noticed that the consumption seemed to increase as I was getting nearer to the time for the oil change.
One other item is that I kept the dealership informed about this website and my responses about their service.
Good luck to you.

I'm still enduring the consumption test. Just was in for the scheduled oil change and continued to discuss this issue with the Dealer. They are still maintaining the company (GM) line that... "expected oil usage for this car is 1 quart every 2,000 miles". I find that totally unexceptable. I also shared the information from these postings, and he just shrugged off information from "blogs" or non-GM websites. I've also advised the dealer that it seems my lifelong loyalty toward GM might be at an end. And now I have to make another hi way trip where I'll be nearly out of oil by the time I reach my destination (350 miles) like the 3 trips before. Getting to know the GM dealers that as much as this one at home! This just doesn't sound like the image GM keeps trying to convince us they are. Pretty sad...

I also owned an 2006 Impala SS that consumed far to much oil. My gut feeling says the root cause is caused by the displacement on demand. Like everyone else, oil consumption was far heaver on the highway compared to city driving.
While driving to Chicago from Indiana I notice an issue when the engine went from 4 cylinders to 8. I could only replicate this problem If I drove 65-70mph on 4 cylinders anywhere from 5-8 miles without engaging all eight cylinders. After the extended 4 cylinder mode driving I would gently press the gas to engage all 8 cylinders and a plum of smoke would exit the exhaust. I am not talking about a small amount of smoke either, It was a significant amount.
The challenge is to keep your car from engaging all 8 cylinders for an extend period of time. A neighbor who owns a 2007 was able to replicate the exact same problem Has anyone also notice this problem?

The latest in this never-ending story is that the dealer added some dye to the oil, then after 500 miles, scoped the engine and under carriage with a black light. I'm still waiting to hear the results but this was supposed to prove the oil wasn't leaking somewhere. A total of 3 different GM dealers have checked every inch of the vehicle and could not find any leak. But anything they want to do to prove the problem is consumption rather than leaking, I'll endure. I just want the problem addressed and fixed. But they still seem extremely reluctant to admit any problem. There was even a factory letter GM published about the 8 cylinder Impala. Same problem but the letter doesn't address my 6-cyl Impala. I'll share the info the dealer offers me (if any); it looks like I'll have to call them because they haven't called me like they promised, and its been over a week. Customer service - what a crock.

After 5 - 6 months of the oil consumption test, and the dye, I had the "check engine" light come on, with a traction warning (while driving in a snow storm) so I had them look at that while doing the next oil consumption check. Several things were "discovered" -
Steering Fluid gear leaking - replaced
Tie Rod Ends loose - replaced
Small Leak from Intake Gasket - replaced gasket
Front Crank Seal leaking - replaced seal
Trans Fluid leak - replaced trans line fitting
Gasket replacement covered by factory warranty
All else covered by extended warranty
We will see if this solves the problems. I'll take it back in 500 miles for another oil consumption check. Does seem to be a lot of "problems" in a car only 4 years old and 51,000 miles! My trust in this car has been severely compromised. I see a trade in near future!
#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.
#63 of 92 Unhappy owner of oil drinking 2008 Impala

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 !
