Ive just completed my first time oil and filter change on my 4200. The filter was a B@stard to get to, and I enlarged the hole in the plastic under tray to get to the tank drain. For the last year, since I owned the car, the pressure stays at 2.5 Bar, hot or cold, but after the oil change it now sits on 5 only dropping a little om idle. I used Shell Helix Ultra despite my usual miserly approach to expensive oil!
Ime certain I haven't done anything else to make this difference, so is it only the fresh un-sheared oil that makes this difference? some of my other cars have oil pressure regulators which limit max pressure.
