My gas mileage is good at about 30 and I have only got 2500 miles on the car. I just wondered what else can I do to improve gas mileage? CAI?

Your milage will go up a bit once you've broken the motor in around say 5k-6k miles. I use a little more fuel than usual because it's so cold up here, but as of now I'm still getting around 37-38.

i get about 25 mpg. I drive 90% highway. I need to keep the pedal off the floor.

If you want better fuel mileage, look at increasing hp slightly, more airflow through the exhaust and intake will improve the engine breathing. free up hp, and get better fuel economy.

I noticed about a 10-15 miles per tank increase when i did my cai and exhaust. that is pretty much 1 mpg.

Aside from that, trying different gas stations, i notice my car goes further (seems to) if i buy gas from the sheetz in slippery rock, than if i use the sunoco on banksville rd.. (since you are local, locations are included). But neither of them seem to be as good as Any BP station. I also have good luck with getgo..

with short air-2 1/2 " pipes with headers I get about 35-37 mpg. with 43k on it.

the engine still needs to break in like wolfman said

Yea I wasn't sure how many miles it took to break these in but 37-38 sounds great.
I usually get gas at the Getgo in Carnegie. I never really try other brands except for getgo or sunoco because of the fuel perks cards.

I always fill up at Chevron fuel stations w/Techron additives. We have a big problem up here with the cold tempatures seperating the molecules in the fuel and creating a lot of water in the fueling stations supplies, but I've never had a problem with Chevron's.

I've been tracking every fill up since I got the car...well since 350 miles. I made an exel file and input the info. I've written my milage down each fillup. Why, just because I guess. I wanted to see the real MPG I was getting.

I have been averaging 28-30.5 mpg. I filled up today and found I got 33+ for this tank. I have 3100 miles on my car. It is an all stock 2009.

I expect it to get better as I break the engine in.

Oh and I'm not babying the thing either. I drive pretty aggresively ...I actually expected less MPG this fillup because of how I have driven it. Go figure!

I have to say that now that I'm at 103000 miles my fuel mileage has been very consitent. Typically I commute 90 miles roundtrip per day and at every fill up I 'm always around 30 mpg. Now also bear in mind that I have an 04 Aveo and its an automatic.

I have a 2007 3 Door 1.2L 72 HP Aveo with 15000 miles on board. The fuel consumption is around 32miles/gallon and that is to much over here in Europe because the price of 1 gallon is around 5.4 dollars and a 1.2 L engine should do around 40 miles according to the owners manual.
