M.B.DOC, On the subject of p/s levels. I have an '80 300SD, and the p/s reservoir on my car doesn't have a "level indicator". I know on my father's '85 W123 there is a triangle piece of metal on the shaft in the center of the reservoir. However, on my car there is a spring (aprox. 2 1/2")on the center shaft. Currently the level is approx. 1/2" below the lip of the reservoir. I have a new filter to put in and want to change the fluid. What should I use as a full mark?
