1. Keep your vehicle maintained properly.

    Your owner's manual will tell you how often you should change your oil and air filters, service your air conditioner, and get regular engine check-ups. You'll not only be doing the air a favor, but also your vehicle will run better, and you'll save money by getting better gas mileage.

  2. Check your tire pressure at least once a month.

    Tires typically lose about a pound of air pressure every month. The label located on the edge of the driver's door will tell you what tire pressure the manufacturer recommends for your car or truck. When you check your tire pressure, make sure the tires are cold, meaning you haven't driven your vehicle for a couple of hours.

  3. Keep your tires properly inflated.

    So what does tire pressure have to do with air quality? When your tires are low, they produce more drag. More drag makes your engine work harder, and that produces more emissions. More emissions equal more air pollution. Bottom line: the right amount of air inside your tires is good for the air outside your tires.

  4. Change your oil and air filters regularly.

    When your vehicle's filters are very dirty, they can't do the job they're intended to do. That's bad for your engine, and it doesn't do our air any good either. Replacing a clogged air filter can improve your vehicle's gas mileage by as much as 10 percent.

  5. Use multi-grade "energy-conserving" oil.

    Every 3,000 miles (or however often you change your oil), consider multi-grade motor oil labeled "energy conserving." Special additives in the oil help reduce harmful emissions and can improve your vehicle's fuel economy by 5 to 10 percent.

  6. Stop at the "click."

    When you're filling up with gas, don't top off the tank. Fumes escaping from the neck of the tank contribute to air pollution. Be sure to tighten your vehicle's gas cap all the way, too. A loose gas cap allows gasoline to evaporate and can cost you up to 30 gallons of gas a year to the air.

  7. Get fuel when it's cool.

    Fill up later in the evening when it's not so hot. High temperatures cook gas fumes and turn them into nasty ground-level ozone that is especially hard on the lungs of kids and seniors.

  8. Travel light.

    Carrying around an extra 50 or 100 pounds in your car or truck makes your engine work harder and use more gas. Reduce drag and reduce emissions by removing items from your vehicle that you don't really need to carry around.
