(Get current gas prices from gasbuddy.com)
Green is good. Red is bad. In the top row of the table below, find the number of miles you are willing to drive to get to a cheaper gas station. In the left column, look up the price difference between the closest station and the cheaper station you want to drive to. If the cell where those two intersect has a green number, that's how much money you'll save by driving to the cheaper station. But if the cell is red, it will show you how much extra it will cost you to buy gas at the cheaper station.
