2011 Maxxforce 13 Oil Pressure

I thought my Cummins was low at 25psi hot at idle. Dang

 

What? Wow! I hope the pressure is better! Just wait until these lighter grades of oil start becoming more popular for increase fuel economy!!!

 

So if I can jump in here is 15 psi at idle when at normal running temp ok for the 2011 maxforce

 

Minimum safe oil pressure is 10 psi. 15 psi is fine. It is a bit lower than what is "typical". Most are around the 20 psi mark.

 

Kind of resurrecting older thread since I didn't feel there is need to open new one of the same subject.
I'm feeling out of my comfort zone in regards to what I'm noticing oil pressure wise.
When I began to drive my truck back in January 2019 outside Temps were very or extremely low so I had no concerns. Since we have 50s and 60's hitting now I'm concerned about my oil pressure. Please feel free to comment based on my recent findings below
Year:
2012
Engine:
Maxxforce 13
Milage:
245k
Motor oil:
Mobile Delvac 1300 15W40
Last oil change:
5000 miles ago
Filters:
Both media and the spinner bought at the dealership by Vin#

Oil Temperatures observed:
Cold start: 90psi
190-195 degrees: 17-18psi
200 degrees: 15psi and 55psi at 1600rpm
215-220 degrees: 12-13psi and 50psi at 1600rpm
Those numbers are based off of NED software. I'd feel comfortable with minimum of 15psi at 220 degrees. I'm afraid that when we get into 80s-90s the oil pressure will drop even more. I have not tested it with mechanical gauge yet.
I'd hate to go as far as digging in crank and main bearings also oil pump since it is internal oil pump (I think) would require front cover being removed?
Engine runs great, no funny noises
My question is: What can I do/replace to start with. My thoughts are oil pressure sensor, oil pressure valve kit. Are there any other items that I can check out/replace myself?
Thanks in advance, Jacob

 

There really isn't a fast and easy fix for this. For sure, your first step is to verify with a manual gauge. As for the pressure relief, it is inside the oil cooler module, which has to come off to replace it. Yes, the oil pump is behind the front cover and a big job too. As for main bearings, this rarely fixes low oil pressure. If the bearings are worn enough to cause a loss of pressure then the crank is already gone. As for what else, the list is as long as an overhaul.
