Does anyone have the specifications on the MB OEM brake fluid?

I'm trying to decide if I want to change it with ATE SL6 or BRF, the only thing holding me back are the viscosity numbers which are 700mm^2/s and 1400 respectively.

If I pick viscosity thats too high the ESP system wont work right (with a 4matic its more critical then in other cars). If too low it might comprise seals.

Also if the MB oem fluid is better then either, I will just buy that.

hope that helps somewhat

Kind of. MB lists low viscosity fluid required but don't give numbers

I found this
http://www.pentosin.net/pressrelease...uperDOT4_3.pdf

Its listed as being a replacement for MB# 000 989 08 07 10 which is our brake fluid. But the pentosin has super dot 4 at 1400 mm^2/s. If I was going with that viscosity I could use and off the shelf fluid. The pentosin low viscosity fluid (@-40*C) is at 700mm^2/s and is not MB approved. So Maybe MB calling their fluid low viscosity is just a marketing scheme? If I could get the numbers I would know.

i would PM e1000. He used RF-650 in his brake flush diy.

I believe the MB fluid is DOT 4+ if that helps any. Personally I just buy the MB fluid since it works just fine.

I have a can of the pentosin super dot 4 because it specifically lists the MB part number. The pentosin dot 4 LV does not, but I think some people use it anyway.

The answers on this thread are a bit surprising. I've been looking into this, myself. I thought I knew that ATE SL.6 was the easy answer other than brake fluid from the dealer. Until this thread, I had never heard of pentosin or RF-650!

Being a new owner who wants to do some of his own maintenance is pretty complicated and confusing!

I bought brake fluid from the dealer...the bottle has MB sticker on it. I expected it to be 'made in Germany' but it's actually made by some company in USA that I never heard of(not pentosin either). So, I guess as long as you do the flush...it doesn't matter what brand you use, just make sure it is a DOT 4+

On the one hand I know what e1000 used and I'm sure it works fine, but is it ideal? IDK I'm the type of person that researches everything. Even the RF-650 is an average viscosity fluid and not in anyway low viscosity like the Sheet 330.0 spec calls for. Ambiguous wording is always a problem. The difference is huge if you think about it, it would be like using 10w-60 instead of 5w30 in the engine. Although its only hydraulic fluid so its not that serious.

I'll prob just go with the MB fluid, its really high value considering the price and performance aspects. (also the piece of mind that comes along with OEM materials doesn't hurt)
