Oil pressure range?

[Dewey]

I'm not saying I agree with it, but the manual says 4 psi minimum at idle. Just scroll all the way to the very bottom, page 12.

Do not run engine if at zero but 4 psi is OK

Just did an oil change with mobile one 5w-20 extended performance full synthetic. Used the Fram 20k mile oil filter this time (Fram XG10060). Last oil filter was a wix XP 57060 XP.

Sitting here just idling getting the oil up to temperature shocked when it said 55 PSI on startup

Typically on idle I run around 33-39 PSI depending how cold/warm it is outside and how quick it gets to temp.

Idling outside temp 52°F
160°F at 46psi
180°F at 40psi
185°F at 39psi after 12 min at idle
192°F at 37psi after 16 min

199°F at 35psi after a full 20 min of idle. Trans temp 159°F. Seems all within the tolerances and seems to be healthy. 25,500miles. 2019 Ram Rebel oil changes done between 5000-6000miles.
