This isn't just an issue with Chevy/GM. Take a look at Edmunds' long-term road test blog. They are frequently adding oil to their cars, including their BMWs.
Several years ago I had a new '99 VW New Beetle. The 2.0L 4-cylinder in that car loved to consume oil. At least a quart every 3,000 miles. There was even a note in the owners manual to check the oil level at every fuel fill-up. I kind of laughed at that initially, but then quickly realized it was a necessity with that car.
I currently have a 2006 Impala, purchased new and now just shy of 48,000 miles. The oil consumption in the 3.5L V6 in mine varies with the kind of oil I am using. For the first 45,000 miles I used conventional oil every 3-4K miles. I would lose and add oil between changes. Last change I switched to full-synthetic Castrol Edge 5W30 as I am going to extend my oil changes and go by the OLM. I checked the oil level a couple of days ago, and with over 2,000 miles on the synthetic there has been no drop in oil level.
Now that I am going to be going ~8,000 miles between oil changes (that is the pace the OLM has me on based on the monthly OnStar reports), I will check it every 1,000 miles or so to make sure the level stays safe. There have been similar stories of owners who switch to full-synthetic and stop losing oil.
My previous vehicle, a 2003 Dodge Durango 4.7L V8, also lost about a quart of oil between changes.
It just seems normal to me.

My 2006 Impala SS purchased new by me started burning 3-4 quarts of oil between 6,000 mile oil changes as typically indicated by the cars computer before it even reached the 36,000 warranty expiration. Dealer has replaced the valve covers under warranty stating that a service bulletin stated the PCV valves which are built into the valve covers were allowing too much air flow in the engine and that the engine was pulling oil back in through the air intake. mechanic stated that this looked logical upon replacement of the valve covers due to the sludge he observed where the PCV valve feeds back into the air intake. Having now driven another 6,000 - 7,000 miles since the valve covers were replaced, total mileage now 46,000, the oil consumption has not improved. I will report the TSB reported in you previous posts relating to the nick in the valve guides and head replacement to see what the dealer tells me. Is there any new information you can provide me with, as the post I am replying to here is over 2 years old?

#44 of 92 Excessive oil usage
Feb 21, 2011 (9:44 pm)
My 2006 Impala is using all the oil in the car at about 2.500 miles. No message stating the oil is low or to add oil. It just runs out.
The local garage says they want to monitor the usage but I feel they are not telling the truth. If your message board is any indication of all the problems, then shouldn't Chev have a better answer by now? I drive my car about 100 miles a month (think little old lady) and only have 35,000 miles on it. I am told it is my driving or lack of driving which causes the problem. Don't believe it but I need more information.

I have a 2001 with 35451 mile on it with 3.8 Ido not use any oil. I use Mobil 1 5-30.

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.
