My vehicle has the 3. 9 l ltz package. It uses 2 to 3 quarts of oil per oil change. I am currently working with the dealership to monitor my oil consumption every 1,000 miles. So far we have used 1/2 quart in 2,000 miles. The dealership does not seemed concerned but frankly my car should not be using any oil. Gm should do something. We have a 10 year/100,000 mile warranty. I hope gm doesn't try to squeak out of fixing this issue.
