My recommendation is to flush (not just drain/refill the reservoir) the P/S system when the transmission and differential oils are due to be changed (5yr/60Kmi max) with the Pentosin CHF-11S (or equivalent) P/S fluid.
The Pentosin CHF-11S Synthetic P/S fluid is the only replacement fluid recommended by MBUSA (the cars were originally shipped with non-synthetic fluid).
