Have you tried to do a tune up on your car? This would entitle new plugs and wires, Oil change, PCV valve, EGR Valve, fuel filter, and possibly O2 sensors is all I can think off the top of my head. You should also check your tire pressure. All of these things will make your gas mileage decrease if they are not in working order or your tires are not at the right PSI.
You can check your PCV valve by pulling it out and shaking it. If you hear a rattle then it is good and does not need to be replaced. I hope this helps you out.
