A lubricating oil detector for an internal combustion engine, the detector including a lubricating oil reservoir adapted to be disposed in a chamber of the engine wherein pressure pulsations are produced by reciprocating movement of a piston. An oil level detecting pipe extends to the exterior of a crank case of the engine, the pipe having an end opening at a lowest allowable oil level in the reservoir. A pressure detecting actuator is provided and is adapted to be mounted on the case and connected through a connecting tube to the detecting pipe. When the oil level is below the lowest allowable level, the pressure pulsations in the case are directed to the pressure detecting actuator, which is then actuated to stop the operation of the engine, or to operate an alarm.
