I also have a "88 300E, my first Mercedes-Benz which I have now had for a few months. My 300E has 200,000+ miles on it and the oil pressure will stay at the max of 3 when you step on the gas but will drop down to 2 at idle and sometimes go as low as 1.5 Being new to MBZ and because of the mileage on my car, I too have been watching the indicator closely. I have been told by a tech not to worry.
