oil sending unit if you have light or gage there is a difference yours would be with out light if you watched it drop looks like o2 sensor on motor
My jeep had the same issue, normally it was when it was in idle. We didn't do tests or anything but found that when we replaced the oil pressure sending unit, it fixed it. We Guessed that its the unit not the actually issue with the pressure...
yes Engine is wearing out.
your oil might be too thin
Low oil level, failed oil pressure sending unit, plugged oil filter, internal engine problem.
Because your oil pump and/or oil pump bearings are dying.
your oil pumps probably going bad
Yes. That is most likely a sensor malfunction and will do no harm. Zero pressure is when you worry.
If its a V8, it's probably the oil pump pickup tube.
Correct. The oil pressure does fluctuate throughout the RPM range.
Hopefully (for you) just a bad oil pressure sending unit Install a manual gauge to actually check the vehicle's oil pressure
Zero oil pressure.
Yes, it is part of the oil pump.
