I find on long trips that putting the car in neutral when going downhill makes a difference. I once got over 100 km more out of a tank of gas simply by using this strategy during a trip from Toronto to Sudbury and back. There is a long stretch up highway 400 that is very hilly so every time I got to the top of a hill, I would put the car in neutral and coast down the hill - sometimes for up to 2 km at a time. Made a huge difference.
Do a google search on "hypermiling" to get other strategies for getting a lot more mileage out of a tank of gas.
