Fuel Saving Tips
Use other vehicles on the road to your advantage when opportunity allows. Driving a safe distance behind a larger profile vehicle helps lower the resistance of your vehicle to still air so your engine doesn't have to work as hard. The result is increased gas mileage. You should not and do not need to get dangerously close to take advantage of this "quasi-drafting" technique. You are just looking for the vehicle in front of you to break the wind. If you have a MPG meter on your car you can test this theory. This technique becomes less useful on hills when the vehicle in front of you prevents you from taking advantage of coasting.
