The invention relates to a method for determining the aging state of a fuel in a motor vehicle, wherein the aging state is ascertained using the dwell time of a quantity of a fuel in the motor vehicle. The method has at least the following steps: a) determining the maximum quantity of fuel which can be stored in a specified fuel tank of the motor vehicle; b) ascertaining the use of the fuel in an internal combustion engine of the motor vehicle on the basis of cumulated injection times of the fuel; c) determining the dwell time of the fuel stored in the fuel tank; said dwell time corresponding at least to a period of time in which a specified content of the maximum quantity of fuel was used; and d) determining the aging state of the fuel stored in the fuel tank on the basis of the dwell time.
