3. When you use your air conditioner you get much lower
mileage so use it sparingly. Try using a lower setting if
you have one. You also don't need your AC on full blast
for extended periods of time.
Turn the AC on until you feel
cool enough, then turn the AC off and let the fan circulate
the cool air. Turn it back on when you get too hot.
4. Take unnecessary items out of the car. Extra weight
effects your gas mileage.
5. Check your tire pressure. Over-inflated tires can actually
reduce your fuel efficiency, so don't overfill.
6. If at all possible, change your work start time to avoid
gridlock. Or try leaving earlier than you normally would
to limit time stuck in traffic.
7. Drive steady and try to keep a constant speed. The more
your speed fluctuates the more gas you will use.
8. Keep your windows closed when traveling at high speeds.
Open windows cause additional drag.
