Abstract: 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 (3) in a measuring section (2); capture of the light (14) passing through the service fluid in the measuring section (2) and/or emanating from the indicator contained in said fluid as a result of a fluorescent effect, by means of a light collector (5), the intensity of the light being influenced by the indicator or indicators or the concentration thereof; generation of at least one measurement signal (8, 9) representing the intensity of the light that strikes.

Abstract: The present invention relates to a method for lubricating at least two units of a vehicle having an internal combustion engine, each unit comprising one or more assemblies, and to a corresponding vehicle. In order to be able to dispense with an oil change of the individual units, and at the same time ensure the necessary quality and quantity of lubricant, it is proposed according to the invention to conduct the lubricant in series through the at least two units in that fresh lubricant is fed to the first unit from a container, at least some of the used lubricant is removed from the oil trough of the individual units and is fed to the unit which is respectively arranged afterwards in the series, and the lubricant which is removed from the oil trough of the last unit is fed to the internal combustion engine for combustion.
