Abstract
A method for operating an internal combustion engine in which at least one secondary fuel injection is carried out, and a device for implementing the method. The level of the motor oil of the internal combustion engine is ascertained, which is compared to a first threshold value for the maximum possible oil level. If a threshold is exceeded, a warning signal is provided. Preferably an oil-dilution signal, which is a measure for the quantity and/or the volume of the oil dilution input into the motor oil of the internal combustion engine by the at least one secondary fuel injection, is taken into account when ascertaining the oil level.
