Here's some helpful links that I've found. I recently got an 07' Jeep Grand Cherokee, and it averages around 15 mpg, so I've been looking for ways to increase my MPG as well.
http://www.wikihow.com/Increase-Fuel-Mileage-on-a-Car - this one is just some general tips on driving habits, engine maintenance, etc...
http://www.fuelinfusion.com - this is for a fuel catalyst that you can add to your tank when you fill up. I've seen between a 10% and 15% increase with it.
http://www.fuelly.com - cool website that I found the other day to track my fuel economy as I try different things to improve it.
Good Luck!
