When you’re filling your vehicle’s gas tank, don’t “top off” the car when the pump stops. When you do, you’re not only wasting gas, but you’re wasting money. Adding that little bit of extra gas actually increases the chances that excess fuel will simply evaporate in the atmosphere. And if your car is newer, it may have something called an “emissions canister” that is designed to prevent fuel vapors from leaking. Adding too much gas renders the safeguard of the canister useless and increases the likelihood of gas leaking or spilling out of the tank.
