Here’s one fuel efficient driving tip that I think is really sensible.
Plan your trip, whether you are going across town or across the country. Try to combine several errands in one outing, and plan your route to avoid heavy traffic areas, road construction, hilly trerrain, etc. With a little organization, you can group your “town tasks” into fewer trips, saving you time and fuel expense. –Eartheasy
Even in city driving, planning your trip ahead will help a lot in fuel efficiency. I suggest you plan your route even before you leave your house (or office, or anywhere).
Going from point A to point B is easy enough. However, sometimes you have to make several stops, and it will be best if you plan which streets to take, and the sequence of stops. And it’s also good to check and double check if you’re not forgetting something you have to do or somewhere you have to go to. Otherwise, you might end up driving back and forth, and this is a waste of time, energy and fuel!
