Automobile fuel efficiency

I ran across a great article on maximizing the fuel efficiency of your car.  The link is below.  The article covers topics such as:

• Keep your tires inflated to the proper pressure.
• Don’t carry around items you don’t need in the car.  For every 100 pounds of weight in your vehicle, fuel economy decreases by one to two percent.  (Several years ago, friends of mine calculated how much fuel they saved by removing the back seat – and then put the back seat in the garage.)
• Don’t speed.  Fuel efficiency goes down when car speeds go up.  HOWEVER, DO NOT drive significantly below the speed limit or the general speed of the traffic around you.  It is dangerous for you and the other drivers on the road.  A slow vehicle on the highway can cause jams that are miles long and cause accidents. 
• Jack-rabbit starts use more fuel than a gradual acceleration.
• Parking in the shade reduces fuel evaporation.
• Don’t let your vehicle idle for more than a minute.  Idling for more than a minute uses more fuel than turning the car off and restarting it.  Some newer cars have technology that does this for you.
