What else should I know about idling?
  • A poorly tuned engine uses up to 15% more energy when idling than a well-tuned vehicle. Keeping your vehicle in good condition is a key to fuel efficiency and reduced emissions.
  • Idling your vehicle with the air conditioner on (to keep the interior cool) can increase emissions by 13%.
  • You can improve your gas mileage by up to 3.3% by keeping your tires inflated to the proper pressure. Under-inflated tires can lower gas mileage by 0.3% for every 1 pound per square inch (PSI) drop in pressure of all four tires. Properly inflated tires are safer and last longer.
