1. By driving 65 mph instead of 75 mph, you could save 20-25 percent.
  2. Driving 55 mph instead of 65 mph could save you 15-20 percent more.
  3. A properly tuned engine could mean 10-20 percent savings.
  4. Simply avoiding “jack rabbit” starts and stops could mean savings of 11-20 percent.
  5. Limit your use of air conditioning on hot days and save up to 21 percent.
  6. By installing a new oxygen sensor, you may save up to 15 percent.
  7. While you’re at it, install a clean air filter and save up to 10 percent.
  8. Keep your windows rolled up while traveling over 40 mph. You’ll save up to 10 percent.
  9. By driving defensively, anticipating traffic conditions ahead, not tailgating and avoiding unnecessary braking and acceleration, you’ll not only be safer but also reduce wear on tires and brakes and save 5-10 percent in fuel.
  10. Keep your tires properly inflated. Every pound of PSI under inflation wastes four million gallons of gas per day in the US, and one tire under-inflated by 2 PSI equals to one percent reduction in fuel economy.
  11. Pack light and clean out your trunk. Every 200 pounds of unnecessary weight shaves one mile per gallon off your gas mileage.
  12. Think aerodynamics and avoid using a roof rack.
  13. Keep your tires balanced and rotated regularly.
  14. Buy gasoline during the coolest part of the day, in the early morning or late evening, when gas is densest. Gas pumps measure volumes of gas, so when gas is the densest you get more for your money.
  15. Maintain clean motor oil by changing it every 3,000 miles.
  16. Maintain properly operating cooling system thermostats. Being stuck in the open position causes the car to run too cool, reducing engine efficiency.
  17. Skip the drive-thru. Idling for as little as 10 minutes while you sit in line can waste 5 or 6 miles worth of gas.
  18. In fact, don’t idle anywhere. One minute of idling uses more fuel than restarting your engine.
  19. Use cruise control on highway trips.
  20. Check exhaust system annually for leaks.
  21. Limit warm-ups to 30 seconds.
  22. Plan and combine your trips.
  23. Make a list and do all your grocery shopping once a week.
  24. Rid your car of icicles and snow build up in the winter as it can add to your vehicle’s weight.
  25. Keep your vehicle’s front-end aligned for better mileage and longer tire life.
