Hi Scotty love your videos. I have a 2012 Gmc Sierra 1500 5.3 with AFM recently had a low oil pressure issue due to gas in the oil I have changed the oil filter and have run fuel injector cleaner through it my issue is that my oil pressure fluctuates about 2-3 psi at steady rpm weither it be at idle or on cruise on the highway and idea what could be causing this??

leaking injectors or fuel pressure regulators often cause that

That would make my oil pressure fluctuate?? I have a manual guage to hook up to the OPS to verify pressure
