10 Ways to Save on Gas This Summer

With gasoline rising by the day and major media spreading rumors of $4 gas on the horizon. Here's a few things you can do to make the most out of the car you have and stretch your gas dollar.

1. Drive cautiously and avoid unnecessary acceleration and breaking: Common sense here.
   
   
2. Check your tire pressure and don't over or under inflate your tires. This can rob you of 1% fuel efficiency for every 2 psi your tires are under inflated.
   
   
3. Check your air filter and replace if dirty. This can save you 1/2 to 1 mpg.
   
   
4. Keep your car maintained and tuned up: This can save you 4% according to my car owner's manual, but varies between makes and models.
   
   
5. Avoid idling and turn your car off if you will be sitting for an extended period of time.
   
   
6. Remove excess weight from your car and avoid transporting items on top of your car on the roof rack or roof top carrier if possible. Extra wind resistance cuts down on fuel efficiency.
   
   
7. Keep the outside of your car clean to save on air resistance.
   

Fuel consumption myths

1. Buy bigger tires: Bigger tires weigh more and don't necessarily buy you any fuel efficiency. Wider tires can create more drag as well.
   
   
2. Run your air conditioner less: Depending on your car make and model, you may actually create more drag and use more fuel by driving with your windows rolled down.

If all else fails you can always start shopping for a hybrid or learn about "hypermiling" (@ Washington Post)
