Libra: Daily green

If you're not walking, biking or busing to work, now's the time to change your car into an eco-friendly vehicle. Check your tire pressure weekly to improve your gas mileage. Avoid using high-octane gas that releases hazardous pollutants in the air and costs more. Drive the speed limit instead of giving into speeding and stopping abruptly. Gas mileage decreases once you go over 60 mph. Open windows instead of hitting the a/c. Don't overload your car with heavy stuff that slows it down.
