Just wanted some feedback on oil pressure gauge readings. My '89 with 13,500 miles shows about 1.5-1.75 sometimes as high as 2.0 bar at idle when warmed up. At 65 mph @ 2,700 or so rpm I show about 4.25-4.75 bar. How does this compare with others?

Currently the car has straight 30 weight dino oil. This is coming out and I'm putting in VR1 20-50.

those readings are fine. 1 bar / 1K rpm (or better) is the usual guideline.

Those are good readings. My 3.2 with 123,000 miles sits at 1/2 bar when the engine is off, so the 1.5 bar at idle is really only 1.0 bar. At 2700 RPM, I hang around 4.0 bar. Shell Rotella T 15W-40 non-syn.
