1.Avoid High Speeds :
As your speed increases, your aerodynamic drag increases in an exponential fashion. Driving 62 mph (100 km/h) vs 75 mph (120 km/h) will reduce fuel consumption by about 15%.
2.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%.
3.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%.
4.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.
5.Keep Windows Closed :
Windows open, especially at highway speeds, increase drag and result in decreased fuel economy of up to 10%.
6.Service Vehicle Regularly :
Proper maintenance avoids poor fuel economy related to dirty air filters, old spark plugs or low fluid levels.
7.Use Cruise Control :
Maintaining a constant speed over long distances often saves gas.
8.Avoid Heavy Loads :
Remove the sand bags from your trunk in the spring and pack lightly for long trips.
9.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.
10.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.
