We're all trying to save money at the gas pump, and here are some small tips you can use to maximize your savings and your car's fuel efficiency. One of the easiest is to wait until your car's gas tank is 1/4 full (or less) before filling up again. Why? When your car is carrying less fuel around, it's lighter and therefore more fuel-efficient. And adding gas just a few dollars at a time is also inefficient; the fewer trips you make to the gas station, the less fuel is wasted.
