Tips: Driving efficiently

Driving right saves money, energy and the environment. This fact sheet from the
Virginia Department of Environmental Quality offers tips on how to operate your
vehicle more efficiently.

Driving more efficiently can save 10 or more percent of a motorist's fuel bill.


  • Anticipate traffic situations to reduce the need for braking and enhance
    safety. Braking wastes energy and, of course, wears out brakes.
  • Fuel economy and emissions reduction are optimized in the 55 mph range.
  • Use overdrive gears if available, which reduces both fuel use and engine
    wear.
  • Avoid unnecessary idling. Most modern vehicles don't require warm-up.
  • Use cruise control where appropriate.
  • Open your windows in lieu of switching on the air conditioner at low
    speeds. The air conditioner saps energy and fuel. But at highway speeds close
    your window and turn on the air conditioner to reduce air resistance.

Maintaining your vehicle for efficiency and the environment.


  • A single tire underinflated by two pounds per square inch (psi) can reduce
    fuel efficiency one percent. Four underinflated tires can reduce fuel economy
    six percent.
  • Purchase tires rated for lower rolling resistance to improve fuel economy.
  • Assure proper wheel alignment and brake adjustment to reduce rolling
    resistance.
  • Use dealer recommended weight of motor oil to reduce energy loss from
    friction.
  • A clogged filter can cause a 10 percent increase in fuel use and increase
    pollution.
  • An improperly tuned engine can result in excess emissions as well as 10 or
    20 percent increase in fuel use.
  • Assure proper recycling or disposal of oil and antifreeze. Also make sure
    used batteries, tires and other components are properly recycled or disposed.
