Several methods were developed for on-line measuring oil consumption in gasoline engine using an oil consumption meter. The oil consumption meter indicates the oil quantity by real-time-measuring the oil level in the sump. In order to measure the oil consumption, the oil consumption meter proposed in this paper requires shorter time, less additional procedures, and shows better results than the traditional drain method. Under steady-state engine-operating conditions, the results obtained through the regression or the difference method show an good agreement with those through the drain method. Under transient engine-operating conditions, on the other hand, good results can be obtained through the reference method.
