Abstract
The description refers to a process for detecting the time for changing lubricating oils, in particular in heat engines. The invention is characterized by the fact that the parameters of pressure, temperature and viscosity of the lubricating oil are measured in situ, the measured values are fed to an evaluator, the actual state of the lubricating oil is determined from the measured values in the evaluator, the actual state is compared with a presettable reference state, and the deviation between the actual state and the reference state is displayed on a display device, and/or, if the actual state deviates from preset tolerance limits of the reference state, an alarm signal is generated.
