Strut coolant fluid?, what goes in Options

[jaxdream]

I scored a set of 89 Carrea Boge struts to use my 914 inserts in.Pulled the 89 insert out looks like the valving set up used in motorcycle front forks (IMG:style_emoticons/default/WTF.gif) Anyway my 914 insert fits in ok just got to come up with centering rings for the insert , my question is do I fill with some kind of coolant , the Paragon article states either oil or antifrezze , or is this not neccesary for a sealed insert unit ??
Strut prt # 911.341.041/042.04

Do fill with fluid or not ?? (IMG:style_emoticons/default/confused24.gif)

I have been told by Koni tech to use antifreeze (they also spec antifreeze on the install instructions). I would expect that if you are using a Boge insert, that Boge's installation instructions should say what to use?

I suspect the problem with oil is that if water does get in that it can/will float the oil out the top leaving a pocket of water at the bottom. This pocket can rust and/or freeze.. While if water gets into the antifreeze that it will still have the anti-rust additives of the antifreeze and it should still protect against freezing in the winter even if diluted somewhat.
