Avoid High Speeds:  As your speed increases, your aerodynamic drag increases in an exponential fashion. Driving 62 mph vs 75 mph will reduce fuel consumption by about 15%.


Do Not Accelerate or Brake Hard:  By anticipating the traffic and applying slow steady acceleration and braking, fuel economy may increase by as much as 20%.


Keep Tires Properly Inflated:  Keep tire air pressure at the level recommended by your vehicle manufacturer. A single tire under inflated by 2 PSI, increases fuel consumption by 1%.


Use A/C Sparingly:  When the air conditioner is on it puts extra load on the engine forcing more fuel to be used (by about 20%). The defrost position on most vehicles also uses the air conditioner.


Keep Windows Closed:  Windows open, especially at highway speeds, increase drag and result in decreased fuel economy of up to 10%.


Service Vehicle Regularly:  Proper maintenance avoids poor fuel economy related to dirty air filters, old spark plugs or low fluid levels.


Use Cruise Control:  Maintaining a constant speed over long distances often saves gas.


Avoid Heavy Loads:  Remove the sand bags from your trunk in the spring and pack lightly for long trips.


Avoid Long Idles:  If you anticipate being stopped for more than 1 minute, shut off the car. Restarting the car uses less fuel than letting it idle for this time.


Purchase a Fuel Efficient Vehicle:  When buying a new vehicle examine the vehicle’s rated fuel efficiency. Usually choosing a small vehicle with a manual transmission will provide you with great fuel economy.
