yea your gas milage is bad then, are you sure your calculating it right?
I would change the fuel filter, both 02 sensors, clean the air filter, run fuel injection cleaner (the expensive kind), change the plugs, and other little stuff. Check the air in the tires. Do all that and you should get much better.
I just got an oil change, everything he told me said everything is fine except for my tires.
