I have an 05 with the 3.6 and it uses about 2 quarts of oil between oil changes and just like everyone else the GM dealership said that it is normal... They actually changed the oil, I drove it for about 1500 miles and they checked out the useage and told me it was within tollerance. I have seen crazy sh*t like this dealing with military contracts and equipment but for it to be acceptable to burn 2 quarts of oil in 6000 miles is unbelieveable! No wonder GM is going bankrupt! (I still love my CTS)
