Calculate your miles per dollar

Above or below $70 a barrel for oil, we're all sick of paying through the nose to drive. So how much exactly are we being abused at the pump?

The Miles Per Dollar Calculator, or MP$, can give you the precise answer to that question as long as you know how many miles per gallon your car gets. And the truly masochistic motorist can even figure the cost of his or her daily commute.

These calculations can be done without the Web, of course. But we're lazy--after all, we're driving, right?
