Horrible gas mileage or a heavier right foot? Those numbers are low 20's for MPG which can be achieved by aggressive driving.

Gas mileage has a whole ton of variables. It all depends under what conditions you're driving under. If you drive a lot on the highway you'll get a lot more out of a tank than urban driving. Having a lead right foot doesn't normally help.

I personally get 250 miles out of a tank and most of my driving is on side roads. It's like an average of 32mpg for me.

When I did a lot of highway driving to school I would get 350 miles out of a tank and averaged almost 40mpg.

My 07 Supercharged does a bit less than three hundred on one tank. That's normal high way and city driving with the occasional race or lead foot.

For me gas mileage is really dependent on what kind of driving I do. Where I live is somewhat in the mountains and I have to use my right more then i'd like to just to keep speed. Also, with the increase of ethanol for the "WINTER" mix of gas will usually drop my MPG about 2-3 per gallon. With all the said I usually get around 220-260 per tank. It really depends on where you live and what type of driving you do. When I took the road trip to CED over the summer I was able to almost 400 to a tank.
