After reading all of the good posts on this topic I would like to know your thoughts with regard to replacing the hydraulic fluid in the reservoir with this NO LEAK power sterring fluid.
On an earlier post I read where the guy said he had a leak. He removed the stock fluid and filled his reservoir with this product, waited about a week, and he had not had a leak for over one year.
Could it be true that this $6.00 product softens the seals?

Lynn,
I remember that same post...wonder how the guy made out now that some time has gone by.
For me, since finding Dennis Ficken, and having mine rebuilt so economically as well as professionally, I'm feeling less experimental with lotions and potions to fix this design flaw. Dennis sent me my old seals and it was evident where/how they self destruct. My sense is that this leak stopper may make the seal slide easier in the piston for a time, but I think that the best that can be accomplished over time is postponing the inevitable. This could be great stuff, so I'm not dissing it; simply that for $30/cylinder to get better than new, I'd rather take that course.
I am suggesting that the Forum consider this product prior to the rest of your seals going out. Why not be proactive and look at it as an adjunct to extend the life of the seals. It may be that the MB fluid is hard on the seals and needs to be reexamined. Or the fluid may need to be changed like Brake fluid due to age. Does anyone know if MB has put a lifespan on the hydraulic fluid?
To me this is a really tempting idea, and like lynn's I would like more information. The rub is I don't want to risk putting something like that in the system on a gamble. Obviously I have no reason not to believe this because we have no feedback either way. Don't we have any chemical engineers in here? Also, I was under the impression that he only added a certain amount, not replaced all the oil with it. Last but not least, where did he hear about using it or decide that would be the way to go.

Chris,
Since I currently have a P/Steering leak and am weighing my options to R&R (DIY or mechanic) I am going to try this product today and let you know if it works in about a week or so.
Neoprene Fibre, Nitrile, HNBR, Viton, Aflas elastomers are all good with Hydraulic Oil, Mineral Oil, Hydraulic oil / Synthetic oil.
But a hydraulic mixture with a pH>9 does have an adverse effect on elastomer rubber, it will become brittle and the elastomer looses its softness (sealing capability)..
I have never analyzed the Hydraulic fluid PN 000 989 91 03 10.
But perhaps if you add this Gold Eagle No leak to the hydraulic oil it may give better life to the elastomer.
You never know Mercedes would have hated for you never to replace the cylinders after 6-8 years, or else there service department would go bust !!
so perhaps they make an oil that will degrade the seals over time ! ! logical to me if i was a Motor producer

Anyone,
Does anyone know the lifespan of the MB hydraulic fluid?
Should it EVER be changed? If so when?
It would be great to know the pH of NEW hydraulic fluid P/N 000 989 91 03 10 . If you have pH sticks.
It would also be interesting to know what the year of your car is and the pH of your current hydraulic fluid. For comparison.
In addition if someone knows the pH of NO LEAK that would give us a good starting point to determine if the differences in pH has an effect.
Thanks for the plug! I really have to agree with you and Snobilt on adding NO LEAK. From what I've seen on the failure of the seals, it can't work as a long term fix. All of the seals fail due to becoming brittle and splitting. Once the seal has split, it's split.
Is there a chance that NO LEAK acts like adding brake fluid to your engine to soften and swell the seals? (old trick from my father-sell the car quickly) What will it do the seals in the pump and the solenoid valves? These are very expensive parts to take a gamble on, but that's just my opinion...
If anyone is needing their leaking cylinders repaired, I'm still repairing any of the R129 or W124 cylinders for $30 each and $10 flat shipping charge.
