3 bar on startup.
1.2 bar on warm idle .9 bar when the engine is too warm after a highway drive with a bad fan clutch. Any application of the throttle moves the gauge to the top. -Jason

1984 300CD
Replacement engine - mileage unknown 3 bar at start up Roughly 2.25 bar at idle after 20 minutes (or how ever long it takes to get above 85*C) 3 bar running at 30 mph. Mine jumps from 2.25 at idle to 3 bar almost instantly off idle. By the time the engine hits 1000 RPMs it is pegged at 3 bar...

1987 300D
255,000 miles 1) pinned (3 bar) 2) a little over 2 bar 3) pinned 1978 240D 364,000 miles 1) pinned (45 PSI) 2) a bit over 30 PSI 3) pinned ... this 240 I've only had since January and have only put about 200 miles on it, but those readings have been consistent. I don't know my Jeep's oil pressure, since it doesn't have real gauges ... plus I assume you meant MBs only.
