I assume you're talking about your location "Akron, Ohio"?
I assume that you're running that OXYGENATED gas crap?
If so, that explains it.
Oxygenated gas will kill, on average, 5% - 10% of your mileage.
The oxygenated additive displaces gasoline, so it takes more of this crap to power the engine.
Oxygenated gas is a @#%*(_%_ conspiracy.
Non-turbo FC's should easily do 15mpg.
Mix in some highway / freeway driving, and it should start to head towards 20mpg.
Start doing some serious freeway driving, and you can easily break 20mpg and start heading towards 25mpg.
At best mileage driving conditions, it'll get close to 30mpg...
To do this, do all your driving in top gear and at 3,500RPM - the key is the RPM's, cause you want to keep it right under the secondary fuel injector crossover point.
