change power steering fluid (or not)

I own a 1996 C180 - the maintenance booklet does not mention power steering fluid. I have looked at a few you tube videos and they all suggest its necessary to change the fluid. The fluid level on mine show just on the minimum and the oil looks very dark. Is it best to have it flushed and changed or do I just top it up?

My car is 25 years old, so i know it wants the treatment ,i to have seen the video it looks easy . So it will be my next job. Do it it can only help your seals in the pump and rack.But i would get mb oil, nothing else for me.

 

worth doing - change the filter at the same time

 

No need to look for MB oil as they don't make it anyway, here is a list from Daimler Benz of their recommended fluids;

When doing this job add a little and turn the steering from lock to lock, add some more and repeat,,if you get air trapped in it can take 1000's of miles to get it out.

 

oil

Frontstep i know a site that sells mb oil in an mb container thats good enough for me not febi stuf . Price £11 for one litre each. You will pay more for aftermarket oil .
