My oil pressure gauge is reading 0 but I am not getting a warning thru my information center
You need to be careful here. If you are driving your Vehicle with ZERO PRESSURE, you are going to blow up your engine.
There is also one of 2 other scenero's for a GM Vehicle
FIRST: Instrument Cluster STEPPER MOTORS are KNOWN to be going BAD in GM's/. If the Stepper Motor is bad, make sure you replace it with a X27.168
SECOND. Your Sending Unit could have come unplugged or the Unit itself went bad.
I am Betting that your Stepper Motor went bad (Happens that Frequently).
I would put a Gauge on the Motor and see what the Oil Pressure Actually is, if it is Truly ZERO... do not start or Drive the vehicle and take it to a Good Mechanic or if still under warranty.. To the DEALER
SOURCE: OIL PRESSURE LIGHT COMES ON AND PRESSURE GOES TO 0 ON GAUGE
Any time the oil pressure is 0 you take a chance of locking up the motor. The only way to know for sure is to put a pressure gauge in the oil pressure sending unit port on the engine and see what the pressure really is. At that point you will either have the peace of mind in the knowledge that the sending unit is really bad and needs replacement or you can then contact a repair shop and tell them what your testing has revealed. I wouldn't drive or run your truck while the oil pressure is at zero.
Good luck

2 things come to mide off the bat loose or corroded ground or cluster going bad

No problem with the oil pressure, the norm is between 40 to 60. Anything lower then 40 you have low oil pressure and anything above 60 then you have high oil pressure which is caused by a blockage in the system.
What is common is the oil pressure gage fluctuating for the first 200 miles if the oil pressure sending unit is getting worn. Good maintenance will keep the engine clean and running good but the oil pressure sending unit is inexpensive and easy to replace. Next time you do an oil change you can have them change the sending unit.
Good luck and hope this helps. You can pick up the sending unit at Auto Zone and most auto parts store and will have the step by step to replacing it. If you do attempt to replace it. make sure you DO NOT USE any Teflon tape or silicon on the threads, they are tapered and need a good ground to the engine for proper readings.
SOURCE: Oil pressure reads high 40 to 60 psi, guage never flucuated this much before new engine
