I get 32+ as well. I keep it 5th at 45mph it usually rides around 2000 to 1800rpm. I shift around 3500 as well. its kind of like a game i play to and from work. But then again I travel 160 miles a day
i just did some maintenance on it, plugs, air filter, tires and new oil and still have yet to see anything different, i started driving less rough and still nothin, still around 29 and 30 doing down hill with a downward draft

some of the ppl on this site go to some extreams but theres a few cobalts on here.
but i would say lower you car that will help with areo dynamics but mainly more on the high way. but then again i just like the look of a slamed cobalt
I have a stock LS coupe and i get 32 MPG on city/highway trips to school and work and im not easy on the petal either. One of the biggest loses of mileage is under inflated tires.
