A method for assessing the deterioration of engine oil

摘要

Disclosed is a method for determining motor oil wear, wherein the viscosity of the motor oil is measured by a sensor and the duration of the oil changing interval is determined in an evaluation unit with a display. According to the invention, a temperature sensor is associated with the oil viscosity measurement sensor in order to determine the oil temperature. The viscosity and temperature of the oil are measured in the cooling phase of the engine once it has been turned off.
