This could mean a few things could be happening. Either the motor is in fact low on oil, the oil pump could be failing or not pumping oil sufficiently or the oil pressure sending unit is not working properly and may be producing a faulty reading.

It shouldn’t go “all the way down,” but it’s normal for engine oil pressure to vary in direct proportion to crankshaft speed. The engine oil pump is driven off of the camshaft, which is directly connected to the crankshaft (albeit turning at one-h...
If the pickup filter gets clogged, then you can have low oil pressure. Likewise, if there is an obstruction or blockage in the oil filter, then this will also result in a drop in oil pressure. The oil filter also contains a pressure relief valve. This helps ensure that the pressure within the system does not overshoot its higher limit.
Another common reason for oil pressure to drop is when the oil starts to break down – remember, your car oil wears out a little bit every time you drive your car. You can check your owner’s manual for the recommended oil change intervals to ensure your car engine is not running on old oil. Oil Pump is Damaged or Worn Out
Therefore, the Pressure drop is the quantity of line pressure, which is the lost forever when gas flows through a device in a gas line. This loss of pressure is caused by the frictional resistance of the parts exposed to the gas. Each instrument and fitting cause some certain amount of drop in pressure.
Two reasons for your oil light to flicker. 1. low oil pressure, meaning you need to top up your oil. 2. faulty oil pressure switch, meaning you might need either a new oil pressure switch if it is defective. Or, you have sludge in your engine and that is clogging up the oil pressure switch causing a false reading.
The most common symptom of low fuel pressure is a wrong air-fuel mixture, which will cause your car’s performance to drop drastically. If you feel that your car’s performance is much worse than it usually is, it is time to check your fuel pressure. 6 Causes of Low Fuel pressure. Clogged Fuel filter; Bad fuel pump; Bad fuel pressure regulator
If your dodge has high miles replace valve cover gaskets, becauce the high volume pump may cause the gaskets to leak. Whoever said ther none for sludge just has no love for a dodge, or is a moron mechanic that is stuck in his ways. High volume pump is the fix $85.00 plus pan gasket.
The oil pressure sits somewhere between 2 and 3. If I step on the gas, the oil pressure immediately decreases a bit (a noticeable move of the needle, though since I am driving at the time I cannot look at it for longer to determine how much exactly it moved) and then increases as the engine RPM increases.
Because the oil pump is engine driven. As the engine speed goes down, the oil pump output pressure decreases. The oil pressure should not drop below about 20PSI. You should hook up a dependable oil pressure gauge and see what pressure is developed at idle. It sounds like you have an oil pump pressure relief valve that is stuck or a sender that is out.
I was having problems with the oil pressure gauge not working when you first start the engine. If you turned the engine off and restarted it the gauge would come up an work perfectly with the exception of every now and then when you would stopped it would drop to 0 but when you gave it gas the pressure would go back up.
