Topping off is when an attendant continues to fill a gasoline tank after the nozzle has clicked off. If an attendant can confirm that a vehicle tank is not full after the click off, the attendant may continue to dispense fuel using best judgment and caution to prevent a spill.

Oregon law now prohibits topping off vehicle fuel tanks during refueling. Topping off causes gasoline drips and spills that release harmful pollution, wastes fuel, and causes vapor recovery equipment in vehicles and at gas pumps to malfunction.

DEQ provides a "No Topping Off" sign and flyer for gasoline stations and distribution facilities.
