STARTING AND OPERATING 285 Materials Added To Fuel All gasolines sold in the United States are required to contain effective detergent additives. Use of additional detergents or other additives is not needed under normal conditions and would result in unnecessary cost. Therefore, you should not have to add anything to the fuel. ADDING FUEL NOTE: If fuel is poured from a portable container, the container should have a flexible nozzle long enough to extend into the fuel filler tube. NOTE: When the fuel nozzle "clicks" or shuts off, the fuel tank is full. NOTE: Tighten the gas cap until you hear a "clicking" sound. This is an indication that the gas cap is properly tightened. Make sure that the gas cap is tightened each time the vehicle is refueled. WARNING! A fire may result if gasoline is pumped into a portable container that is inside of a vehicle or on a truck bed. You could be burned. Always place gas containers on the ground while filling. 5 CAUTION! To avoid fuel spillage and overfilling, do not "top off" the fuel tank after filling.
