I have a ford expedition (yes kill me). I've added a K&N filter and keep the tires well pressurized. But what other things can I do to improve my miles per gallon?

Tune it up if needed (plugs, wires, etc), check and change PCV valve, use the proper octane rated gas for the vehicle, run a bottle of fuel injector cleaner in your gas tank every 5-6 tankfuls, check and replace the fuel filter if necessary, use full synthetic or synthetic blended oil (pricier but better for the engine), drive sensibly (no quick starts, speeding)...and oddly enough, keep the car clean & waxed...there are stats to back this up, plus I'm convinced that clean cars are more aerodynamic, run better, and are more fuel efficient. Hope this helped.

How different is your real fuel economy number from what is supposed to be (EPA posted rate)? If it's close, then there is not much you can do. If your fuel economy is way worse, just take your car to a dealer or a mechanic and let them diagnose the problem. With the emission testing machnie it's fairly easy to find out what's wrong. It could be something like oxygen sensor, or fuel injectors need to be flushed. But really, I know you don't like to hear that, but the best way is to get a smaller car or SUV if you like - you can rent the truck when you need it for the money saved on gas.

Drive smooth. No quick starts, get to speed and keep it there. It takes less gas to keep it in motion than it does to move it. Seems simple but look at how you drive, do you do quick starts, pass people all the time? Cut in and out of traffic? Keep it steady. Keep the car in good running order. Good luck.

Flowmaster cat-back exhaust will improve power and fuel mileage. I wouldn't bother chipping it. Chipping a gas engine isn't cost effective for what you get in return.

Stop driving it. Only drive downhill.
Seriously, drive on highways rather than city streets as much as possible, keep gas pedal steady in same position as much as possible, turn off air conditioner, avoid jackrabbit starts, consolidate trips, use carpooling, and ride public transportion if possible.

Jeezzz...some people and their answers!
Anyway, there are several good performance/mileage enhancing chips out there now that are pretty reasonably priced. Just make sure the one you select doesn't void your warranty.
I've got the same problem with my F250 4x4, and am looking into chipping it.
And YES, people, I NEED to drive a truck! :-)

Rethink your questions, and ask your self why you care about gas mileage when you have a 5.4 liter engine. Take your car and tie donkeys to it. That is the best gas mileage ever...

Drive it off a cliff. Then it won't use any more gas.
YOu in or out of the car when it careens down the cliff is up to you...entirely optional.
