Why do they let this ride? I hope they fixed this problem. My Chevy impala started burning oil over the last 4 oii changes. 1.5 quarts of oil at last change 81,430. I know all engines can suffer from this especial with high wear (beating on it), mileage, not warming up on cold starts 32or less, improper oil change intervals. but i can say none of these reasons are possible. i have taken care of this old lady at the age of 3 yrs old! burning oil is alright for the environment we live in and the air that are kids breath? Not in a opinion of an engineer or an environmentalist. I would hope that chevy perfected the 4 stroke gasoline engine that they have been making for long f in time you know? If they want to go that way why not bring back the 2-stroke? I believe this is quality issue. material specifications, clearance specifications, engineering error, craftsmanship of worker, or cooperate idea to score more future repairs then realised its happening way sooner than they thought? oopps!! were's the government in this? o yeah they don't drive American cars at home they are so loaded anyway what's engine in there kids new car? 5000 bucks o i'm just going to have buy you that BMW u wanted for Christmas. Mass producing cars in not quite the way to go with lossy materials and designs and poor craftsmanship. Why not make something that Europeans would want to buy at mid range over say BMW 325 or Mercedes C class. And yes that mean's interior and electrical/computer Quality too!
i hope some reads this Cmartin

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.
