This is related to my run-hot thread.... I seem to recall that the (base) MB spec for oil pressure at hot idle in an OM617 is 1 bar.
I am getting ~1.5-ish bar at idle hot in park, even when the car is running hot, but it drops further and faster, to 1 bar in gear once the engine has really got hot, or I'm in dead traffic, and can even sneak just under the 1 bar mark in traffic jams. So I am constantly shifting into neutral when waiting. Question: what is the spec, and is it spec'd for neutral/park or idling in gear?
