Look, we love gadgets and gizmos around here. What we don't love is the fact that you have to have a PhD in physics to figure many of them out. Not so with the Econodriver Fuel Monitor ($80). This one is actually useful and easy to use. All you do is plug the sensor in under your dashboard and synchronize the sensor with the key fob. Fill your gas tank, enter the price you paid for fuel, and reset the Trip Report button. It takes less than five minutes to set it all up, but you'll suddenly have the information you need to know exactly how much you're spending on gasoline, how much it costs to get from Point A to Point B, and how much you might be wasting. Forget what the car manufacturer says about your MPG. You'll have the real-life numbers right at your fingertips. All of this knowledge can only help you build a better budget.
