At idle near nil?
Does it increase immediately with just a small bit of "throttle?"
Obstruction in pump pickup in oil pan?
Oil press on my 81 300D was suddenly at 0 at idle one day after a stop for
lunch; increased nicely with a bit of "throttle," drop back to 0 at idle; 3
bar at normal, etc., speed; I drove few blocks home, being sure to keep
pressure up. Stealer picked up car on roll-back; MB tech found pieces of
vac pump in oil pump intake; he remembered that vac pump on this car had
disintegrated several years before I got it from 90-year-old friend.

Subject: [MBZ] dirty oil
I have about 1k on the recent oil fill in Frosch. Oil is black as night
and nasty. Granted, I used rotella 20-50, but being a vergasser, there
should not be the diesel sooting up of oil.
What is the group consensus on early change of oil? Should I just go
ahead and toss in fresh oil and filter, or wait another few thousand? Oil
pressure at idle is near nil, but at speed, I have great pressure.
