Gas calculator

I had to fill my tank today and noticed that the price of gas is trending up again. Curious, I looked up historical charts for gas futures, and found that prices do tend to peak in the summer.

I also found an interesting gas calculator site. It has a couple different applications. You can plug in the price of a barrel of oil to see what that means to you at the pump in dollars and cents. And you can figure out exactly how much a more fuel-efficient car would save you in fuel costs.

There is also supposed to be an application to track your MPG and cost per mile, but I couldn't get it to work.
