3. Slow down and drive at speed limit. Cars use about 20% more fuel driving at 70 miles per hour than they do at 55 miles per hour.
4. Avoid using air conditioning whenever possible. Air conditioning reduces fuel economy by 10% to 20%. Use air ventilation system instead.
5. Don't drive with open windows when traveling at high speeds. Open windows on highway can reduce fuel efficiency by 10%. It's much better to use ventilation system.
6. Remove car racks and other items which make your car less aerodynamic when they're not being used. Leaving them on only makes your car less fuel efficient and costs you money.
7. There is no need to let your car idle. Even on cold mornings, cars don't need to idle more than 30 seconds. Newer cars are designed to be driven almost immediately and letting your car idle longer is a waste of gas.
8. It's more efficient to turn off your car and turn it on again than to let it idle for more than 45 seconds while waiting.
9. Remove all excess weight from your car. Many people use their car trunk as a storage space adding unneeded pounds to car's weight. This unnecessary weight reduces car's fuel efficiency by about 1% for every 100 lbs.
10. For most cars, higher octane gas is simply a waste of money. Regular unleaded (approx. 87 octane or so) is least expensive and what you should purchase. It's important to remember that octane is a measurement of how hard it is to ignite gas, not quality of gas. Purchase mid or high octane gas only if your engine pings, knocks or rattles when using regular unleaded fuel.
