のオイル交換時期通報装置。[Scope of Claim for Utility Model Registration] A hydraulic pressure sensor that is installed near the turbocharger in an oil supply system of the turbocharger, communicates with the oil passage through a small hole, and receives the hydraulic pressure in the oil passage; An indicator that operates in response to the output signal of the sensor and notifies the driver when it is time to change the oil of the turbocharged engine; an oil change sensor that detects when the oil has been changed; and a carbide removal device that operates in response to the problem and removes carbide, etc. that is blocking the small hole and opens the small hole. The indicator operates only when the small hole is blocked and the hydraulic pressure in the oil passage is no longer transmitted to the oil pressure sensor, and the carbide removal device operates only when the oil is replaced. An oil change timing notification device for a turbocharged engine, which is characterized by:
