38-40 MPG is very doable with just a little bit of care. 35 MPG is very doable on any highway trip. Not too bad for a midsize car.
You're right in regards to my NVH comment. The Ecotec is much smoother than other 4cyls I've owned. I'm sure it related more to the car it's bolted in. The stellar MPG figures I see owners post has always puzzled me. I do 90% straight hywy travel with my 2.2L, auto, base model Cobalt and the best I can do is maybe 33.5mpg tank to tank (warm weather)and that's rare. Sure, short hywy bursts can yield more, but tank to tank averages are typically 29-32mpg. Fillup to fillup avg. is the only figure that matters IMO.
