PURPOSE: To enable a single body of nozzle to prevent feeding of erroneous kind of oil and to make such a nozzle easily retrofitable to an existing oil-feeding apparatus by a method wherein a control means which releases control of a valve opening control means only when an oil kind detected by an oil kind detector of an oil-feeding nozzle coincides with an oil kind stored in an oil kind memory is provided. CONSTITUTION: A control device 38 receiving a drive signal from a switch 33 outputs a normal drive signal to a pump driving means to drive a vapor pump 32 in the normal direction, and sucks vapor inside a fuel oil tank into a sensor chamber 31 from an opening 25a having its one end at a position near the front end of the discharge pipe through a vapor tube 25. As a density detected out of the vapor sucked into the sensor chamber 31 is outputted to the control device 38, the detected density is compared by a judging means with an oil kind stored in an oil kind memory. As the detected density is found to agree with the oil kind in the memory, a solenoid drive means excites a solenoid 34, making a valve-opening lever 29 drawable with a stem 35 retreated, and thereby a main valve 28 is opened and fuel oil can be supplied form an oil-feeding nozzle 5.
