$tretching Your Gas Dollar$

You can't do anything about the seemingly ever-rising price of gas, but there are roads you can take to make what you spend on it go further.

Among his suggestions:

Tune Up Your Car -- And Your Driving!

Driving less aggressively could cut your gas use as much as 20 percent. Avoid "jackrabbit" starts and stops. Don't "fly into" stop signs. On the other hand, don't coast through them, either.

Avoid excessive idling. It's VERY expensive. If you're going to be sitting for a minute or more, turn off your engine.

Get your car tuned-up regularly, keep your air, gas and oil filters clean, and keep your tires properly inflated.

All politics and business aside, we have to seriously consider the benefits of owning a hybrid.
