Attached please see my RST hydraulic fluid yesterday (1-10-2010) 2.5 years and 12K miles later for comparison to the above.

Now about my four speed gearbox

We've had some confusion as to which pumps belong with which year car.

Since you have a 1993 doesn't your pump look like the one above?

Yep, the one in the above photo is the actual pump in my 1993 SL500 which I posted in the original topic starter but somehow the photos have been switched in my original post to a much later pump which is why I was hoping the same thing would happen to my '93 gearbox to a much later 5 speed model

Wow.
I see that with time lot's of things have changed.

Last time that I gave a urine specimen, it was in a clear glass.
Now I see they have them decorated......
Maybe it was because of the Holly days?

Hmmmm.
Why not....
What I don't understand is what this has to do with a four gear change to a
five speed gear pump?
Hm?
No,,,,,,, it can't be that.
Mechanical cats?

Have you notice how clean the pump was in one of the picture ? (the one below aam's urine sample).
It must be Lynn's (I bet he wax the inside of his trunk too)

FYI-I went ahead an waxed the spare tire area and put Aerospace 303 on all the other stuff so l would be worthy of lynns efforts.

Here's where I have to bite the bullet.

Yesterday I was at my local MB Dealer Parts Count and asked him to match the Parts.com $9.49 print out for p/n 000989910310 hydraulic fluid and he said he could sell it to me for $12.00/Liter rather than his $23.10/Liter MSRP so I bought two Liters rather than pay Parts.com shipping at $24.52 I paid tax for a total of $26.10 in California. For a +$1.58 and I didn't have to wait 7-10 days for ground shipping.

Mutch to my surprise the MB fluid is ROOT BEER in color and the Febi-Bilstein p/n 0009899103 is CLEAR. So my assumption that the age of the hydraulic cylinder seals was contributing to the dark color is probably wrong. But not with stanfing the more important part is that the oil has been renewed.

But I did notice that when I poured about a one inch amount of each oil into a clear plastic glass and swirled it it appeard that the MB oil moved faster than the Febi. I wonder if there is a difference in viscosity between the two?? and I wonder if it matters to the seals and/or the RST operation??
