Cool, now here's your first tip:

If you don't run your AC all the time, you can get immediately gain about 5-8 mpg by "engine-off coasting" up to all stop lights and stop signs.
#1 - As soon as you see you're going to have to stop, let your foot off the gas, throw it in neutral and key it off.
#2 - Your power brakes are good for about two pumps before they stiffen up, so ease onto the brake pedal in one long, continuous light braking action until you roll to a stop.
#3 - Key it back on when the light changes.
