autumn55mn,
An oil consumption is the first test the dealer would need to do. Please keep me updated on your progress.

Through constant checking on the oil levels, I have determined that the problem exists when I take the car on a trip which is longer than one hour at freeway speeds. The dealer is still tracking the usage but that is all. Since most of my driving is local, it took a while to locate the problem. It is not what I expected of a Chev.
Thank you for your interest in my problem.

I have an 06 ss with 41,000 on it now it has been driven mainly in town with occasional trips with no oil usage but now my wife started driving 45 miles each way 5 day's a week and it has started using oil like crazy,1.5 quarts in 3000 miles.I am taking to the dealer now this should come under the powertrain warranty?

That sounds identical to my problem. As long as we drive in town, there is no oil usage but on infrequent road trips, it will use one quart or more. The dealer has me driving an additional 2,000 miles and is checking the mileage and usage. He says he will then send a report to Chev. I am hearing things like a possible ring job but I don't know what that is. Although I have explained that the problem only appears on trips with highway speeds, they don't seem to get it. How can driving another 1,000 miles in our small town give them any more information. Good luck to you. Please keep me informed if you can. I would certainly appreciate it.

After checking the mileage every 1,000 miles for 5,000 miles, the dealer got the ok to do something. They said they found the seals were not tight on the intake and they are doing something about that today. Hope this is the end of the problem.

I have the same car and had the same problem. The dealer just got the ok from GM to replace the intake valve and all the other seals around it at no cost to me as they determined that was the problem. My car has only 45,000 miles and didn't have such severe usage as you have but what they found was the usage increased the closer I got to the 3,000 miles without changing the oil. I was told the problem is fixed but will be watching it closely.

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.
