How have you improved your fuel economy?

I have. While going to college it is all highway miles, I don't get that every tank because I am usually running late. If I keep my speed at 70 mph it is easily done.

You're not doing it in Beckley.
Sorry.
Maybe on some of the downhill trips
I've driven all around that area, and the only way you will get 40 mpg for a whole tank of gas is in an XFE, and drive on flat ground.

I didn't say in the city of Beckley, I said when commuting to college about 50 miles all highway.That being said, when i drive in town with stop and go traffic I am getting around 27-29 mpg

I get 35-40 in my 2.2 XFE on the highway, though I think my air filter is disrupting that. I'm burning fuel like a V8 all of a sudden. Depends on what roads you drive on and how you drive on them.

Make sure your tires are air correctly.
And lose some weight from the car.

My buddy is getting over 40 on the highway and all's he did was went to a K&N cold air intake on his 06 LT. This is the first thing I am doing to my 06 LT. Next I would go to the improved catback exhaust system which should further improve mpg by 2-3 (some report higher but this is where you need to start to "chip" the system to maximize the changes in air flow and exhaust).
One caution though, both of ours are manual transmissions which get greater mpg to start with.

I get 40+ (2.2 XFE) but I live in Texas it's all flat and it's all highway miles
The #1 way to increase fuel economy (assuming you've kept up maintenance) is to reduce rotating weight. On cobalts this mostly means lighter wheels and tires. On trucks and it's axles and drive shafts... And don't carry around a bunch of junk in your car. Ditch the tool box get onstar or AAA XFE's don't have spare tires or jacks for this reason.
You can look at ultra low rolling resistance tires ( the trick is they're lightweight) but the performance is total crap. Great gas mileage but a nightmare on wet roads.

The MPG difference between auto and manual is almost negligible. Auto transmissions have come a long way since the 60s. They get about the same now.

I agree that the automatics have come a long way but when you are talking about overall weight factor in increasing gas mileage manual transmission is still the way to go. Manual transmission for the cobalt is still about 100lbs lighter than the automatic.

its debatable on that point. weight versus perfect shifting.

ya ... oil and air filter ... tire PSI .. should go without saying . the best MPG saver is a ecotec sticker .. i heard a chevycobaltforum.com sticker works better but cant find one ....

Fuel Economy Improvement
Some suggestions:
check out the ecomodder.com website for general ideas.
consider using tufoil (tufoil.com)
If your engine has lots of miles on it, make sure its clean inside (seafoam, auto-rx for examples)
For something completely different: rvsmaster.com
Best of luck!

Fuel mileage? What's that nonsense? lol Might help if I had any sort of a linear throttle response. Turbo doesn't help any with that, quarter pedal pegs me at 1psi off the line.
