'93 525 Touring self leveling fluid?

Shogun,
you are quite right - I went out to check again (wearing my reading glasses) and on the center top of the knurled knob was stamped "CHF11s". I totally missed it as I was looking for a big label or sticker. Here in the states I'm most familiar with a BMW proper (for E28 or E30) long life low phosphate antifreeze being amber/orange in color - the green stuff is not what I expected, though the latest long life Dexcool I bought was green, so color may no longer be a good indicator. E34 recommended antifreeze is different from E28 or E30?
Thanks, Tom Walrod

Antifreeze:
some are greenish.
For example the BMW approved Glysantin which is new has a purple colour.
The Glysantin Protect Plus/G48 is blue-green.
Just do not use Glysantion Protect Plus/G05 which is yellow colored, as this is for heavy duty cast iron engines. Unfortunately I can only find at the moment the German page.

If your car is 1993 and has LAD, there is Pentosin CHF11s inside. Pentosin CHF 7.1 was used in early models.(at least that was for E32 models)
Buy some Pentosin and compare it with the fluid inside. Use a white paper kitchen towel and dip it into the reservoir.
What is mentioned on the cap of the reservoir?

BMW antifreeze is Cool Blue and is for all BMWs, at least for what we are talking about here.
