Im pretty sure a Bird rolls the same way but it sure doesn't sound normal. My car for instance, 95 Bird with 160k and an oil leak at the sensor......
From a cold start: 80
Few miles of driving (~10 miles): 45
Longer drives: 35
All at a redlight/standstill....mind you I have a leak. So I expect it to get better after that's fixed. I'd get yours checked out

My '95 Z reads a little low as well. Though I've heard many LT1s runs low psi regularly.
All readings taken from the in-dash gauge.
Cold idle: around 40
Cold driving: >50 (50 to 55)
Hot idle: 20-21
Hot driving: <40 (38 maybe)
When the RPM drops off idle to let the clutch out, it dips closer to the red, but as soon as the RPM climbs, pressure approaches 40. Dipstick shows a full oil pan.
I want to hook up a mechanical pressure gauge and see if the in-dash is accurate or not. I'd be happier with about 10 extra psi across the board.

(It's behind the intake manifold, UNDER the cowl, with LOTS of plumbing/tubing/wiring harnesses in the way (if they were not all removed, like many on here do). Thread Starter

The car is fine. As long as oil psi increases steadily during acceleration everything is good.
My 98 trans am had 20 psi warm idle but rose to 45 psi with rpms. As long as the pump is building pressure its ok to drive

like mentioned above..use thicker oil 10w40 should be good try if that does anything ,and replace oil pressure sending unit.if the issue is still there you will need to replace oil pump..been there done that

Also, these pressure readings are ALL higher in the cold winter months.
Is my engine the exception on here, as my hot idle pressure NEVER drops below 40 psi (at least according to the factory cluster gauge), and the ~2000 rpm, HOT, cruise/steady state pressure is never below ~55 psi, and WOT HOT pressure is never below ~60-65 psi???

lol when i'm cruising it's around 55-60 psi.
