22+ psi on idle.
If it's below 22 psi then make there is enough oil inside the engine,

<44 psi on top rpm
ALL oil filter are bypassing as 50 psi for safety.

During normal drive,it your read out can range from 22-50 psi

It should drop quickly.

A slow drop read is a indicator or oil and or filter break down /blockage.

You will see the needle move quickly after oil change,

Low oil pressure/ guage fluxuates but runs low


Sounds like a valve lifter or in queens english a hydraulic tappet ,Now what i used to do on the rover V8 was to add a tin of gunk brand name exterior engine cleaner and then let customer have the car back and do some miles,or as soon as the noise stopped ,then change the oil and filter and add the diesel/petrol turbo engine oil as this is detergent and then change the oil every 5/6000 miles with a oil filter every third oil change ,if no engine cleaner then try half a litre of diesel or just change the oil for one detergent type diesel engine oil you will not hurt the engine using this oil the cheaper it is the better as well .In extreme cases i give a 2 second squirt of fairy washing up liquid to the oil as well ,has to be fairy mind them cheapos are no good for this job .Stop worring about it and just do as i say

2002 4.8l gmc yukon oil pressure problem


My suggestion would be to check it with a mechanical gauge.
You would need to use a Tee fitting to use the sensor to have fuel pressure.
If the mechanical gauge shows steady pressure at idle, it could be a problem in the wiring or the instrument cluster.

Why do i have high oil pressure on a 2006 yukon (80psi)


Not uncommon for oil pressure to read @ 80psi when oil is cold an thicker or a heavier weight oil, however, does it fluctuates or simply stays @ 80psi cold or at running temp? if so, its normal, if it stays there and doesn't move, that may a bad guage or sending unit. consider this and get back.

Your oil pressure will flucuate with the rpm of your engine. It is generally higher also when the engine is cold as the oil is thicker. This is normal as long as your oil pressure stay in the normal operatting range.

The oil light keeps on flickering even though I checked the level and it's at the correct level. I even checked all other levels for all other fluids and they are all correct. What can be the reason that...


There are a number of reason that could cause this: bad sensor, low oil pressure, wire rubbed and grounding out.

You need to screw out the oil pressure sensor and screw in a pressure guage then crank the car and observe the guage. It should stay above 20 psi at all times.

Does it flicker when idling or driving or both?
