07 convt g6 gt MPG suggestions ?

[crashderby]

I have a 2007 Convertible G6 GT, 3.9
I know that estimated MPG listings for cars are exactly that - Estimated
I also know that tires, oil changes, filters, etc. can all effect MPG
I live in sunny South Eastern Georgia (if that makes a difference)
I keep my oil changed and tires inflated .. and my air filter stays pretty clean
I do fuel injector cleaners frequently
I'm getting around 17 MPG in city .. I drive my car very easy

Is there any suggestions on how to get better gas milage ? I'm hoping to aim more towards 20 MPG ... or to at least get 300 miles per tank (which I'm currently getting about 250-275)

Someone I work with suggested a canon air filter ... ? Has anyone tried anything like this yet ?

do you know what mileage you get on the highway, if around 30mpg there is nothing wrong with your car. You can try adding about 2 psi to the recommended cold tire inflation number.

All I have to say is HP costs, a smaller engine would get better mileage.
