None of those things are going to get you 11.5MPG. What kind of driving are you doing? Something has to be seriously wrong if it's not all bumper to bumper driving. Like a leaking injector which should set a code.

There are many factors to consider when it comes to MPG. General tune of car, tire pressure, hard acceleration (are you racing people from the light), high speeds (are you going over 70), extra cargo (do you have a big stereo or transport alot of people), what type of gas you use, are you driving into wind all the time, driving with the windows open?, heavier wheels.
