Tips for Greater Efficiency

Proper and timely vehicle maintenance has a direct effect on your vehicle's fuel economy. This in turn has an impact on the amount of pollutants generated by your vehicle.

Proper Maintenance

  • Check monthly: Underinflated tires can decrease your gas mileage. By spending just a few minutes a month to check your tire inflation, you could save yourself a lot of money.
  • Check each winter: You may want to check your tires more often in the winter. Tires will lose about 1psi of pressure for every 10 degrees Fahrenheit drop in temperature. Keep an accurate tire pressure guage in your glove box and check the tires when they are cold.

Optimize Your Driving Habits

  • Drive smoothly: Aggressive driving (speeding and rapid acceleration and braking) can lower your gas mileage by as much as 33% at highway speeds and 5% around town.
  • Observe the speed limit: Each 5 MPH you drive over 60 MPH can reduce your fuel economy by 7-8%.
