Hi Bobbi... if you don't have a ScanGauge yet, you'll find that it's an invaluable tool. It's taking me a while to learn how to drive economically in the city with a heavy vehicle. Key thing is to get into 5th quickly (about 60% full load on the engine), and coast whenever you can. It's too bad the diesel versions aren't sold here.
Good luck and good patience... ;-)
