A pressure sensor 2 is arranged at the oil drain hole 100 at the lowest end of the oil pan 1 and is connected with a data acquisition device 4 through a lead 3, the oil level height H ' is calculated by measuring the oil pressure P ' of the oil pan 1, the corresponding H1, H2 and H3 are calculated according to H ', and the oil consumption m2 is calculated. The calculation can be made according to the following equation:
ma1＝f(H1)……………………(1)
ma2＝f(H2)……………………(2)
ma3＝f(H3)……………………(3)
m＝ma1+ma2+ma3………………(4)
