Tips for Improving Gas Mileage

Empty the trunk! Extra clothes, overdue library books, tools and the bag of aluminum cans that you have been meaning to take to the recycler all weigh down your car unnecessarily.4
Carpool whenever possible or practical.
Listen to radio reports for alternate routes around congested areas.
Drive in the highest gear possible (without lugging the engine).
Try to keep your speed constant. Use cruise control when on long stretches of road.
Notes:
According to the U.S. Department of Energy, nearly four million gallons of gasoline could be saved nationwide each day for every one pound per square inch (psi) of tire under-inflation, recommended pressure.
The U.S. Department of Energy estimates that for 145 million passenger vehicles idling five minutes per day, approximately four million gallons of gasoline are consumed without going anywhere.
According to the U.S. Environmental Protection Agency and Oak Ridge National Laboratory, a vehicle loses about one percent in fuel economy for every one mile per hour above 55 m.p.h. that it is driven. A passenger car that averages 30 miles per gallon at 55 m.p.h. could typically get 28.5 m.p.g. at 60 m.p.h., 27 m.p.g. at 65 m.p.h. and 25.5 m.p.g. at 70 m.p.h. Remember, however, that for different speeds, the changes in fuel economy will vary by vehicle model.
Each 100 pounds of needless weight will cost up to one-half mile per gallon, on the average.
