What is the normal oil pressure for a BMW?
1 Answers
BMW's normal oil pressure ranges between 300kpa and 350kpa. Oil pressure test: Turn on the ignition (without starting the engine) to activate the electric fuel pump. The fuel pressure at this time should meet technical requirements, generally fluctuating around 0.3MPa. When the engine is idling, the reading on the oil pressure gauge is the idle working pressure of the fuel supply system, typically 0.25MPa or as specified by the vehicle's technical standards. When checking idle working pressure, removing the vacuum hose from the fuel pressure regulator should cause the oil pressure to rise to 0.3MPa; otherwise, the pressure regulator should be replaced. Hazards of abnormal oil pressure: If the oil pressure gauge shows low oil pressure, it can lead to insufficient lubrication at the crankshaft, connecting rod, camshaft bearings, and other areas, resulting in abnormal engine noises, unstable operation, and reduced power.
