A measurement device measures engine oil consumption of an engine lubricated by engine oil. The measurement device includes a sensing pipe housing in which a sulfur dioxide sensing pipe arranged to sense the sulfur dioxide is disposed, an exhaust gas introduction passage connecting the engine and a first end of the sulfur dioxide sensing pipe, and arranged to introduce the exhaust gas from the engine to the sulfur dioxide sensing pipe, and a flow amount measurement device arranged to measure the flow amount of the exhaust gas flowing in the sulfur dioxide sensing pipe. The engine oil measurement device is small in size and able to measure engine oil consumption easily.
