u need to replace oil pump
Not enough oil.
Clogged fuel filter or weak fuel pump.
Yes, low oil level can cause low pressure.
Leak in the hydraulic system pressure drop is caused. Pressure drop measured by a manometer. There is oil leaking hydraulic oil, along with signs of connections.
The oil gets thinner. It is normal for the oil pressure to drop after the engine has reached full operating temperature. If you have from 30-40 psi pressure when the engine is hot then that is normal.
It is normal for the oil pressure to drop some when warmed up.
No. A drop in oil pressure can be nothing more than a faulty oil pressure sending unit. It can also be caused by a weak oil pump, worn piston rings, worn bearings, or defective oil pressure gauge. The catalytic converter will not cause this.
It is normal for the oil pressure to drop when the engine is warmed up and at an idle.
THAT IS SIMMPEL IT IS THAT URE CAR DONT NEED ALL THAT OIL PRESSURE WEN ITS SLOWING DOWN
As the engine speed increase so does the speed of the oil pump. the faster the pump turns the higher the pressure becomes. When changing gear the engine speed drops along with the oil pressure.
it may be the oil pressure sender located on the engine
