In hot weather, gasoline vapors escape during refueling and, mixed with sunshine and heat, create ozone, an air pollutant that can be harmful to our lungs. By refueling your car's gas tank during cooler periods of the day and in the evening, you can help to reduce this air pollution. Also when you gas up, don't top off the tank. It's safer and helps keep the air clean.
