Oil pressure

My 92 is showing to have low oil pressure on the guage it is at the low end of the guage but not in the red. It has 367000 miles on it. Finally got the fuel problem straightened out. The guage has been reading low for 75000 miles now i was wondering what to check. Any tips or help would be great.

I was just wondering about this myself. I have an aftermarket oil gauge; what is considered normal idle oil pressure (PSI) for a 6.9L?

At cold idle I run at 40psi, hot idle 15-20psi. Running at operating temperature I am at 40-45psi at 2200rpm. I have read here that these engines are high oil flow not high pressure.

That's the same as mine, 17 warm idle, 45 cold start, and 40 driving around 1500rpm. That's what I get

Huh. My high-rpm PSI gets between 30 and 40, typically. I've been worrying about the oil pressure at idle, though (12-15 psi), since I worry about spinning a bearing. But I guess that's pretty normal for this engine.
