Should my oil pressure fluctuate while driving?
This is normal operation for your oil pressure. The faster the motor spins, (RPM, revolutions per minute) the faster the oil pump spins creating higher oil pressure. I have had to do this on a number of occasions with odd oil pressure symptoms. To reiterate, a rise in oil pressure with higher RPM’s is normal.
Why does my oil pressure drop when I come to a stop and?
When I come to a stop the oIl pressure goes down to almost nothing and the red check gauges light comes on. Once I drive off, the check gauges light goes off and the oil pressure goes back to normal. Because the oil pump is engine driven. As the engine speed goes down, the oil pump output pressure decreases.
What should I do if my oil pressure is low?
All you do is remove the original sending unit and then screw in the adapter for the oil gauge. When you start the engine, it will read an accurate pressure. If it showing good pressure at an idle, then you should replace the sending unit.
What should the oil pressure be at idle?
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. helpful? helpful?
Can a high engine speed cause low oil pressure?
High engine speeds can cause faster than normal wear on crankshaft bearings, especially if combined with low-quality engine oils and longer than specified intervals in between oil changes.

Why does my oil gauge keep going bad?
If installing a thicker viscosity oil raises the oil pressure, then something major is wrong inside the engine. Besides, modern cars are designed to use very thin oil anyway. Gauge Problem vs Oil Pressure Problem Dashboard gauges do occasionally go bad, but it is very rare.
How do you check your oil pressure while driving?
Locate the oil pressure sending unit on the engine (the parts store can sometimes tell you where it is), remove it and follow the instructions that come with your universal oil pressure gauge to hook it up. Then drive the car and see what the gauge does. Be careful to watch the road as you do this. Don’t become fixated on watching the gauge.
