You don't need a new car to save on fuel. Small changes to how you drive and maintain your vehicle add up quickly.

Drive smoother

  • Accelerate gently and anticipate stops so you brake less.
  • Keep a steady speed and use cruise control on the highway.
  • Ease off at higher speeds — fuel economy typically drops quickly above about 50–60 mph.
  • Avoid long idling; if you're parked, turn the engine off.

Maintain your car

  • Keep tires at the recommended pressure.
  • Use the motor oil grade your manual specifies.
  • Replace a clogged engine air filter on older vehicles.
  • Fix check-engine issues promptly — a faulty sensor can waste fuel.

Lighten the load

Remove heavy items you don't need and take off roof racks or cargo boxes when you're not using them; they add weight and drag.
