Tips for Improving Your Gas Mileage

With today's high gas prices, it's worth taking a few minutes out of your day to make minor modifications that will improve your gas mileage. ALLDATA's ASE certified technicians have developed 22 effective tips for reducing the amount of gas you use while driving your vehicle.

Vehicle Tips

  • Keep your tires properly inflated, and check them frequently.1

  • Keep your front suspension and steering in proper alignment.

  • Use the thinnest viscosity oil that your car's manufacturer recommends (5W-30 for most newer cars).

  • Keep your engine in proper mechanical condition.

  • Keep your engine in tune and make sure the air and fuel filters are clean.

  • Make sure your brakes are not dragging.

  • Repair body damage. That crunched front fender adds aerodynamic drag - just ask any race car driver.

  • Don't use premium fuel if your car does not require it (check your owner's manual); using it is an unnecessary expense.

  • Don't waste your money on those late night "as seen on TV" products that are supposed to increase your mileage.

  • Avoid excessive warm-up time. Modern engines do not require it.

  • Don't idle your engine for long periods. Turn off your engine when you leave the car or have to wait a long time.2

  • Avoid jack-rabbit starts.

  • Keep your speed at 55 miles per hour or less whenever possible.3

  • For newer vehicles with aerodynamic designs, close the windows and turn on the A/C when driving on the freeway.

  • For older cars with inefficient A/C compressors, use the ventilation system and close the windows, temperature permitting.

  • Anticipate merging traffic and stoplights; decelerate and accelerate smoothly.
