How To Improve Your Car's Gas Mileage

Here are some of the things you can do to ensure improved gas mileage for your car:

Driving Habits

  • Using cruise control on highway trips can help you maintain a constant speed and, in most cases, reduce your fuel consumption.
  • Heavier vehicles use more fuel, so clean out unnecessary weight in the passenger compartment or trunk before you hit the road.
  • If you anticipate being stopped for more than one minute, shut off the car. Contrary to popular belief, restarting the car uses less fuel that letting it idle.
  • Wide-open windows, especially at highway speeds, increase aerodynamic drag and the result is up to a 10% decrease in fuel economy.
  • The faster you drive, the more fuel you use. For example, driving at 65 miles per hour (mph) rather than 55 mph, increases fuel consumption by 20 percent.
  • A fouled spark plug or plugged/restricted fuel injector can reduce fuel efficiency as much as 30 percent.
  • Look for cracks or missing sections or segments. Worn belts will affect the engine performance.
  • This will extend the life of the vehicle's tires.
  • Limit car warm-ups in winter.
  • Clear out the trunk. More weight equals more drag.
  • Use overdrive. If your car is equipped with overdrive gearing use it as soon as your speed is high enough.
  • Keep your car clean. Mud on the undercarriage can weigh a significant amount and slow you down.
  • Don't throttle the gas or brake pedal! Sudden starts or stops use more gas than gradual changes in speed.
  • Consolidate your daily trips and errands. This will also save you the cost of restarting your engine, which uses a lot of gas.
  • Avoid air conditioning when possible. However, when driving at higher speeds, having your windows open also creates drag
  • Don't idle for too long. Turn off the engine if you anticipate a lengthy wait.
  • Avoid high speeds. We know this is almost impossible to resist but you can improve your gas mileage by up to 15 percent driving at 55 mph rather than 65 mph

Servicing Your Vehicle

  • Change your oil and oil filter as specified in your manual more often (every 3,000 miles) if you make frequent short jaunts, extended trips with lots of luggage or tow a trailer.
  • Low oil makes your engine work harder.
  • Use high-quality or synthetic motor oil.
  • Keep tires properly inflated and aligned. Check regularly to ensure your wheels are fully inflated and your alignment is good.
  • Change your filters. Dirty filters can sometimes increase the amount of fuel your vehicle uses by as much as 10 percent.
  • Get regular engine tune-ups and car maintenance checks. A lot can go wrong with a car. Damaged spark plugs or transmission problems can also contribute to poor gas mileage.
  • Replace the spark plugs in your engine regularly. This way, the air and fuel mixture will burn cleaner and more efficiently.
  • Improve the intake/output system. By allowing gas to get in and exhaust out of your vehicle you will improve the vehicle's overall performance and gas mileage.
