I know this has been hashed out before but it was a number of years back so I figure I'll put it out here again.

My '99 E320 (basic) is due for a power steering flush and I want some opinions.
I will be doing the flush whilst the pump is turning, etc.

My real focus is what fluid is alright to use? My daughter went into AutoZone (or Advance) and they told her "dealer item" (I haven't needed to add any since I have had the car so do not have any). No dealer close by and she is in town with the car so I want to do it this weekend so no mail-order. Are the newer "power steering" fluids acceptable for use, anyone have any issues with any of them? I read a post ExxonMobil was supplying the dealer fluid.

Would a name-brand P/S fluid be OK or is it critical I use MB/Febi?

Thanks...
