  • Method and device for automatically measuring oil consumption of an internal combustion engine and for changing the oil of said engine
    Patent number: 7946159
    Abstract: A method for measuring an amount of oil consumed by an internal combustion engine including an oil pan for supplying lubricating fluid. The method: causes the gravitational flow of the oil contained in the engine oil pan, from the oil pan towards a measuring tank; measures and stores a first value of the oil volume contained in the measuring tank; subjects the oil contained in the measuring tank to a pressurized gas thrust causing the rise of the oil from the measuring tank towards the oil pan; and repeats the preceding method at least once to obtain a second value of the oil volume contained in the tank.
