So what is your definition of "low oil pressure"? I recall reading that idle oil pressure down to about 0.3 bar is okay, but I rarely see less than 1.0 on my 190e 2.6 five speed(idles in neutral at 700), and it pegs the 3.0 max gage reading by about 2000.

It drives me nuts on these automotive forums when guys say my car "overheats" or has "low oil pressure", but rarely if at all ever mention actual readings from their dash gage and the driving and ambient temperature conditions at the time.
