What causes sudden oil pressure loss?
Engine Wear If the oil level on the dipstick is between “add” and “full,” a possible cause of low pressure would be worn engine bearings, especially if the engine has very high mileage. Excessive wear reduces the original flow restriction, which consequently drops the pressure.

What should oil pressure be after changing oil sending unit?
OIl pressure still drops after changing oil sending unit? When truck is first started, oil pressure is normal, around 40 psi. When engine temp starts up, oil pressure slowly falls until “Stop Engine – Low Oil Pressure” warning comes on. Switch truck off a few second, maybe 20-30, restart truck and back to 40. And on and on.
Why is the oil pressure in my car so low?
As such, there is not enough oil going up the pipe. This can result in low oil pressure. Pressure can also drop because the pump is no longer functioning as it’s supposed to. The work of the oil pump is critical since it facilitates the movement of the motor lubricant throughout the system.
