It's the simple things. Air filter, tire pressure and press lightly on the little pedal on the right. At 93k I'd look at the plugs and see. Maybe the previous owner had them changed. Make sure all fluids are in good condition and topped off

I noticed a big change when I put a new fuel filter on. Also, check and make sure that your thermostat is functioning normally. If it's stuck wide open, the engine will run cooler then designed and your mileage will suffer.

Here are a few things that I have found to be great for fuel economy. This goes for any late model car.
o2 sensors is a biggy "Have made HUGE gains just by this alone"
Cataletic Converters
If EGR is in place it needs to be operational
ALL Filters applicable
Clean MAF wires/probe
Plugs & wires of course
Fuel system clean "injectors"
A good dyno tune will improve milage as well as power.
Like the other fella said....Keep your foot out of the go-pedal when you can. This is really key.
Good Luck,
Brad

We just got back from Outer Banks, NC this weekend in my '01 5.4 4x4 and with a full load of luggage and 4 adults, we were getting between 17.3-18.2 MPG. Yes, this is on a vehicle with 91k miles on it.
Hope this helps,

Bumping your tire pressure can help with MPG, but be careful when you do it. If you overinflate the tire for the load you are carrying you end up riding on the center of the tire and will wear that out quicker. You also shrink your contact patch and that can be a very bad thing if you come on adverse road conditions. I make sure to keep my tires inflated properly for the load I am carrying and leave it at that. Tire pressure doesn't make a huge difference in mpg assuming that you are not 15psi low to begin with.
