Default Oil pressure question

Hi im running into an issue maybe... im not sure i would like to know other people advice to make my mind.

im running an ap1 f20c built motor for 3 years now, sleeves pistons acl race bearing skunk2 rods studs etc
I run the SOS oil filter relocator and the oem oil cooler


I installed an oil pressure (aem digital) only couple months ago. And here is the numbers:
- cold start 95-100psi
- operating temps 18-20psi
- idle after 30 mins highway, some random pulls 13-16psi
- driving normally at operating temps (3000rpm) 60-65psi
- cruisin on the higher at 65mph ( 4200rpm ) 65-75psi

i hear no weird engine noise. No knock , the engine pulls good. Im just getting nervous since i put that gauge in

Im very worried about my idle oil pressure being so low.. right now i have 5w40 in.

That looks normal.

If its of any comfort to you, mine drops into single digits while idling after a track session as well. Engine runs and has no issues. I do run an external oil cooler so there's some pressure loss there.

Im really happy to see that my oil pressure seem normal to you guys.

I know the turbo really doesnt help on cooking oil. I change it very often because im so scared lol

What cooks the oil fast on a turbo car is not letting it cool down before shutting the engine down. On my truck with a Cummins N14 putting out 41psi of boost(525hp&1850tq.) I had to let it idle for at least two min, most of the time 4 to 5 min. before shutting it down. Got to cool that turbo first.

Those pressures are normal...for worn bottom end bearings. Especially if your oil squirters were removed/plugged
