One of the simplest ways to save fuel is to learn how your vehicle operates most efficiently. You know how when you pull up to a light on a two-lane road and you have that irresistible urge to gun the engine at the first hint of green? Yeah, well, stop doing that.
Light acceleration and coasting to a stop are the keys to maximizing your car's fuel-economy potential. Jackrabbit starts and gunning the engine suck up dramatic amounts of fuel, and, trust us, saving three seconds on your trip is not going to be worth it.
Also, remember that your car is most efficient at a low speed in its top gear. For instance, driving at 40-55 mph with a five-speed transmission will get you the most bang for your buck. The faster you go after that, the more wind resistance will steal your miles back.
Let us know about your driving habits. Have you adjusted them recently due to high fuel prices? Would you consider doing so now?
