Update. Just got back from a weekend road trip. My best average on a tank of gas was 37.5 mpg while traveling a relatively flat stretch of highway with no a/c on setting the cruise at 64 mph. My worst was 30 mpg while loaded up with camping gear and climbing a lot of hills.

replaced CO2 sensor by smalltown

I have a 2005 Spectra5 with a little over 30,000 miles. My "check engine" light would come on and go off in a day or two a few times a month for the past 3 or 4 months. The dealer was finally able to isolate it to a bad CO2 sensor. After a replacement under warranty, my mileage improved a little. On the highway it went from 29.5 to 32.5 MPG. In town MPG went up about 5%.

I've gotten anywhere from about 24 to 38. I need to update my MPG chart, I was keeping an overall tally but I stopped about six weeks ago. I believe I will get 40 or better in strictly highway driving, if I don't have to use E10.

OK, I found and updated my graph paper.
First tank was 36.6, and from there I've gotten 31.0, 21.9 (two tanks of E10), 31.9, 30.7, 26.2, 29.6, 33.7, 29.5, 39.9, 31.1, 35.5, 32.5, 26.1, 37.2 on last tank.
Total of 3729 miles, 115.76 gallons = 32.2 MPG overall.

I get anywhere for 27-32. Mostly shorter trips, but have taken it on some longer trips and can't get any better than 32.
Could be that I don't have cruise but for some reason on my 06 it wasn't installed.
Even though it has been on every automatic that I see. What's up with that KIA?

Cruise is optional on most/all Spectras. Mine had it ($250) and pinstripes ($0) but it was not standard on most Spectras.

But I have yet to see it on a manual transmission car(which I have).
Test drove an automatic before I bought mine, and it had cruise.

MPG by Ripp1971

I have a 2008 Kia Spectra5 5 spd manual transmission.I am getting around 30 MPG running around town and 35 on the HWY running at 78mph on cruise control im sure if I slowed it down to 65 or 70 it might have gotten around 38 to 40 MPG... The only Modification I made was to add a K&N air filter which increased the air flow to the engine. I plan on adding a cold air intake to it which will boost the Horse Power and also allow even more air flow to the engine which will increase the fuel economy.

Increasing air flow will not improve the mileage on an EFI engine.

Since my 37.2, I've gotten 25.9, 28.6, 29.0, 24.3 (winter snows begin), 27.9, and 33.4 on the last tank. Overall average at this point is just under 32.
I would expect at least 35 on a road trip, and given a 14.5 gallon tank, that gives a stretch-out range with one gallon reserve is over 470 miles.
At 38 MPG that makes 513, and 40 give you 540. IMO that's doable.
