ABSTRACT:
A device for indicating the oil level of an internal combustion engine crankcase comprises a crankcase oil level sensor electrically connected to a change-over switch provided in the electrical connection between the engine fuel tank level sensor and its fuel indicator, thereby allowing the same in indicator to be used for reading fuel and oil level selectively. The change-over switch preferably forms part of the ignition switch so that oil level reading is prevented when the engine is running.
