    Re: Typical oil consumption for a 3.6?

    GM says 1 quart every 2000 miles is acceptable. If your car consumes more than 1 quart every 2000 miles, that is excessive. Be aware that GM will fight you every step of the way to not fix this problem. On my 2006, it had oil consumption issues since day one. At 30,000 miles, after several oil consumption tests, they pulled the engine and put in new rings and valve stem seals, but no cylinder work. That will help for a short time. In my case, about 10,000 miles later, back to high oil consumption (1 quart every 800 miles). I pressed for an extended warrenty, GM denied it because the entire car is a POS, but gave me a component coverage letter on the engine. After several more oil consumption tests, they put in a new engine at 65,000 miles on the cars odometer. Yes, I am bitter about the whole thing. You would be also after buying a new car and having it require over $24,000 in warranty repairs. And yes, that gets noticed when you want to trade it in, which is why I am still driving this car.

Then again, the minute I got the car, it was pedal to the metal to finish breaking the engine in if needed (which is not as those engines are broke in from factory).
    What do you mean by 'special ordered'. My CTS was ordered as well. Its coming up on 100k miles and I drove it hard from from the 1st start. I didnt redline it until 5000 miles, but I ran it 'city-hard'...50-75% throttle, varying rpms from 2000-4000 consistently. I did a couple extra oils changes early on, as well. I think I had 4 engine oil changes by 10000 miles, and all fluids replaced once by that point. I see about 1/2 qt every 5000 miles and I drive it hard. Seems those of us who have driven the car hard from the start see no serious oil burning issues....

    I feel for you, only if you mean YOUR CTS is a POS. Good luck with another brand. All of them will treat you the same way. They will step on you until the NHTSA tells them to watch where they are walking.

    With the CTS on the other hand, around 2K is when the sweet spot starts, meaning right when the light turns green and that's in a V6, that's why I love driving my car, I'm having fun all over the rev range it's like having a junior V8 under there
    While I applaud you support of the CTS (Im a huge 1st gen V6 lover...have owned a few and have been driving some version of 1 since 04), I have to call you on the Miata comments. The Mazdaspped Miata will take a stock 1st gen V6 in every performance category besides top speed. There is very little little turbo lag, and makes good power everywhere as well, especially in such a light package.
