The first summer we had it, we drove to Maine for vacation. About 240 miles each way, all highway.  I drove and I usually drive conservatively so 60-70mph. Both there and back we achieved 43mpg over at least 50 miles. I kept it in the mileage logger because I thought it was so good. Within a couple years, one of the cam actuators crapped out and both intake and exhaust were replaced. It occurred to me, sometime after that that our gas mileage was nothing like it used to be. The best highway I can get is 33 mpg and mixed is about 24. I see the current mpg is about what others are posting but I was curious if anyone else has had a similar experience or if GM changed the actuators and they no longer function the same.</p></blockquote><p></p>
