Mounting structure of a sensor for sensing change time of car oil is provided to effectively notice oil change time to users, and to recognize existence or nonexistence of an abnormal state of a device by including a pressure sensor and a sensing sensor. Mounting structure of a sensor for sensing change time of car oil comprises a pressure sensor and a sensing sensor. The pressure sensor includes a sensor housing and a membrane disposed inside the sensor housing, and senses oil pressure. The sensing sensor is disposed inside the sensor housing so as to be located at an upper stream of the membrane. The sensing sensor includes a light emitting unit for emitting light to oil, and a light receiving unit(140) for absorbing the light generated from the light emitting unit and converting to a resistance value.
