エンジンオイルの制御装置。 A sealed reserve tank is provided that communicates with the bottom side of an oil pan storing engine oil and is located at a higher level than the oil pan, and the upper space of this reserve tank is communicated with a negative pressure source via a first control valve. Additionally, an oil temperature sensor that detects oil temperature and an oil level sensor that detects oil level are provided in the oil pan, the oil temperature sensor being connected to the upper space of the oil pan via a second control valve. a lower limit oil control section that controls to open the first control valve when the detection signal from the oil temperature sensor is below the lower limit temperature and when the detection signal from the oil level sensor is above the lower limit level; and an upper limit oil control section that controls the second control valve to open when the detection signal from the oil level sensor is below the upper limit level.
