Your still well within acceptable pressure range. Is this Idle or cruising pressure? Maybe filter starting to get plugged from soot is not at all uncommon especially with aftermarket filters. Changing the oil might come back up. Get pressure gauges hooked up and measure drop across the filter if your unsure.
What oil are you running? Delco or Dello?Rideandrepair and QUALITYTRUCK Thank this. -
Is " Witch oil " , some sort of concoction brewed up in a cauldron ?

I’d go with canola or corn. The farmers need our help!! Willie Nelson said so.
