Best I found is 20L for 250$, that's $12.5/liter:

If you're doing the whole system flush, then there is this alternative:
Pentosin Power Steering Fluid Pentosin CHF 11S 20 Ltr : Amazon.com : Automotive Pentosin Power Steering Fluid Pentosin CHF 11S 20 Ltr : Amazon.com : Automotive

At $11/liter...

All my readings have indicated that Pentosin has a shelf life..... my question: is buying 20L over kill being that I most likely wont replace the fluid again for another 3-4 years? (a group buy would be awesome right now) lol

Someone correct me if I am wrong. 10L should be more than enough fluid to flush the whole system?

Yes, I did it twice within two years.
First time a flush and second time just empty tank and refill.
I bought the 20L and still has 1/3 left.

I used this pentosin alternative when I replaced my abc pump (complete system flush) on my '05 S600 with No issues. No doubt there may be some naysayers, but it worked for me.

Amazon has 20L jug for 10.63/Liter Amazon has 20L jug for 10.63/Liter
($212.62) with free shipping.

Don't forget, Pentosin is Hygroscopic (absorbs water) same as brake fluid so it must be sealed and stored properly for the next flush cycle.

I recently bought a 20 liter jug from Amazon and did the ABC flush. The seal on the pouring mouth of the jug is very good, but I also put a thin film of plastic across the opening before I put the seal cap back on and tightened it. Don't want the balance of about 9 liters absorbing water over the next ~2 years!!
