The invention is directed to a method of detecting disturbances of the crankshaft rpm for an internal combustion engine which are caused by an empty tank. Uneven-running values (LU) of the engine are detected which are distributed in bands of values and the spacing between the bands of uneven-running values (LU) is computed. A quantity of the engine is detected which is relevant to the exhaust gas of the engine. A check is then made to determine whether the computed band spacing is less than a pregiven threshold spacing and whether the exhaust-gas relevant quantity lies within a pregiven threshold value interval and, if so, this data is utilized as an indication that the disturbances of the crankshaft rpm are caused by an empty tank.
