Welcome to the forum!

Start with instrumentation. If your car doesn't already have a fuel economy readout, you can make one (MPGuino) or buy one (ScanGauge or equivalent).

Then start reading through the list of driving techniques and working on that. It's very rare that someone can't improve their economy quite a bit by modifying their driving style.

After that, you could start looking for ways to modify the car itself. 65+ Efficiency Mods

There have been aerodynamic modifications that have been implemented incorrectly, but the failures are the fault of the creator and not the actually modifications themselves.

Everything on this site equates to more MPG.

Yes, there is a thread on here called "the worst ecomodders ever" or something like that. I believe it's in the "Ecomodding Central" catagory. I know I've seen a couple other threads complaining about not being able to get any positive results, too.
