the melling 10296 in my truck makes some crazy oil pressure. i idle at 60 psi and go down the road at ~77 psi
Lower oil pressure mid OCI, PF48

Update: Two weeks' of commuting into the new filter and everything continues to be normal on the oil pressure gauge. Something was apparently amiss in that AC Delco filter and changing it out got pressure back to normal.
My 2013 suburban does that. At first, I was changing oil and filter to resolve it. I Evaluated the pickup tube O-Ring by unofficial means of overfilling by 2-3 qts and putting truck nose down on a incline. No change.
Found the bolts on the VLOM loose. Front 2 bolts are accessible. Tightened the ones I could reach without removing the intake and this helped, (was getting 25-28ish psi if memory serves.
This weekend however, noticed hot oil pressure below normal (for this vehicle) was about 30-32ish psi (dash gauge) was running Fram endurance, replaced it with wix and oil pressure now back to 38ish hot idle.
New, the Fram endurance typically would yield roughly 38ish hot idle, but I too notice oil pressure seems to drop a few psi after a few months into the OCI.
