Driving and Maintaining your Current Vehicle
•Some of the oldest advice still can lead to big savings on gasoline!
–Try not to accelerate quickly. By one estimate, you can save 31% by driving moderately as opposed to aggressively.
–Avoid excessive idling. If stopping for longer than one minute, it is more efficient to shut off your vehicle. Savings up to 19% can be realized.
–Keep your engine tuned. An improperly tuned engine hurts gas mileage by an average of 4.1 percent, according to U.S. government studies. Most important to mileage is a properly working oxygen sensor, which can increase or decrease your efficiency by as much as 40 percent.
–Keep tires properly inflated. The US Department of Energy estimates that you can improve mileage by 3.3% by inflating tires regularly.
