We are doing the oil test they wanted to do now. I did find a tech bulletin that says 1 quart in 2000 miles is acceptable. That's BS. That is GM's way of skirting the problem. We'll see what happens. If anyone of us built an engine and it used a quart of oil in 2k miles, we would tear it back down. It's still a great truck, but will be gone at the end of the warranty.
