My 07 Suburban with 158K miles usually runs 50-60 lbs of pressure at all times. The other morning I remote started it to warm it up for about 10 minutes. I get in and drive maybe 300 feet and the "no oil pressure, stop now" message shows on dash. I immediately turn the truck off. After a minute I restart and pressure goes to normal, so I head back to the house. Before I get there the pressure is back to zero. I park it and drive a spare vehicle.
That evening I check the oil and its less than a quart low. I start it up and it shows good pressure for about 5 minutes and then drops to zero. The oil (Mobil 5000) has 7000 miles on it and my filter is an AC PF48.
So I change the oil and filter and now have normal oil pressure.
Is the oil filter to blame?
