When the ignition switch is turned on, the oil pressure is generally 280 kPa, the idle oil pressure is 250 kPa, the maximum oil pressure is about 750 kPa, the adjusted oil pressure is about 300 kPa, and the remaining oil pressure is about 150 kPa.

If the semi-oil return system can only measure the static and idle residual oil pressure. The idle speed of semi-oil return system is mostly around 400 kPa.

Extended data

Oil pressure refers to the residual pressure of crude oil flowing from the bottom hole to the wellhead. It can be divided into static pressure and flowing pressure. The oil pressure during shut-in is called static pressure, and the oil pressure during production is called flowing pressure, which is less than static pressure due to friction and sliding resistance loss. Static pressure can directly judge the decline of formation pressure, while flowing pressure is related to production, and flowing pressure decreases with the increase of production.
