Filling Up

Q: When filling up is it OK to top off the tank?

A: You should not top off the tank. Topping off the tank increases the likelihood of spills and can cause excess fuel to evaporate in the air. When this happens you are polluting the environment and wasting money spent on fuel that you are not using. Fuel vapors are toxic and bad for your health. Overfilling can also cause your car’s fuel vapor system not to work properly. Besides, your tank needs additional space for fuel to expand. To avoid any potentially hazardous situations, stop fueling when the pump clicks the first time.
