What is the oil pressure of Buick Regal?

Under normal circumstances, the oil pressure of Buick Regal in Pacific Auto Network should be no less than 50kpa at idle speed and around 300-450kpa at medium and high speed.

Between 300 and 350.

1. Turn on the ignition switch (do not start the engine) to make the electric fuel pump run. At this time, the fuel pressure should meet the technical requirements, generally swinging around 0.3MPa.

2. Clamp the oil return hose. At this time, the reading of the oil pressure gauge is the maximum oil supply pressure of the oil pump, and its value should meet the technical requirements of the vehicle type, which is generally 2~3 times of the working oil pressure, that is, 0.5~0.75MPa.

3. Loosen the tubing clamp, restore the static oil pressure, remove the jumper of the oil pump relay, stop the operation of the oil pump and wait for 5 minutes. At this time, the reading of the oil pressure gauge is the maintenance pressure of the fuel supply system, which should meet the technical requirements of the vehicle type, and generally should reach about 340KPa.

4. When the engine is idling, the reading of the oil pressure gauge is the idling working pressure of the fuel supply system, which is generally 0.25MPa or meets the technical requirements of the vehicle.

5. When detecting the idle working pressure, unplug the vacuum tube on the fuel pressure regulator, and the oil pressure should rise to 0.3MPa, otherwise the oil pressure regulator should be replaced.

3. When the throttle valve is fully open, the reading of the oil pressure gauge is the rapidly accelerating oil pressure of the fuel supply system. Generally, when the throttle accelerates rapidly, the oil pressure should rise rapidly from 0.25MPa at idle speed to 0.3MPa, or meet the technical requirements of the vehicle.
