A method and a device for the automatic detection of at least one fluorescent and/or light-absorbent indicator contained in a liquid service fluid during the filling of a machine, in particular a combustion engine of a vehicle, with said service fluid are provided. Detection takes place in the following manner: irradiation during the filling of the service fluid to be analyzed using at least one light source () in a measuring section (); capture of the light () passing through the service fluid in the measuring section () and/or emanating from the indicator contained in said fluid as a result of a fluorescent effect, by means of a light collector (), the intensity of the light being influenced by the indicator or indicators or the concentration thereof; generation of at least one measurement signal () representing the intensity of the light that strikes.
