Alright everybody, let's get a discussion of driving techniques to improve fuel economy. I'll start it off: 1. stay in the highest gear possible for your current speed. 2. consolidate short trips into one, so your engine stays warm. 3. keep your tires properly inflated. 4. coast in neutral down hills. 5. minimize A/C. just run the fan, if you can stand it. if you can't, though, A/C is usually more efficient than open windows at freeway speeds. feel free to refute these suggestions, verify them, or add your own.
