Steering pump Fluid and filter for W116

[Cream 280SE]

Hello all

What is the correct and best power steering pump fluid to use for the W116 280se.

Also , the filter in the pump. Mine is like a round piece of hard cork or similar.

Can this still be purchased?

Thanks

Mercedes as well as most all car manufactures want you to use only their SPECIAL lubricants and fluids HOWEVER for over 40 years I have used and still do in all my older Benzes 1958-1989 plain old Automatic Transmission (Dextron 1 11 or 111) with ZERO problems ever.
Your Round Cork Like filter can be back flushed with a good Cleaner like BrakeKleen or naptha and or replaced and I think they are still available .
