I have to admit I have often questioned the wisdom of M-B's design of the oil pressure gauge scale but some things they do just defy logic or wisdom. The serenity prayer comes to mind.

For example, on our brand new C300, they have a temp gauge which they have thoughtfully put in the same location as the fuel gauge is on my E300 and reversed the fuel gauge to be where the temp gauge was...while that isn't disorienting enough, they have the car running at 90C but still have 80C as the "horizontal" spot on the gauge...so it always looks like it is running "hot" even though it is designed to run at 90C (at least that is what I have been told) so the needle never points at or near the horizontal position but always looks to be high to people used to the old style where 80C was normal and at near horizontal...again, just an annoying issue they should have addressed but didn't.
