Abstract

A method and device for determining a fuel portion in a motor oil of a motor vehicle. The motor oil is brought between at least two electrodes forming a capacitor. The capacitance of the capacitor is determined while the motor oil is located between the electrodes, and the fuel portion in the motor oil is determined from the capacitance of the capacitor.
