who installed them?
i've replaced my boge fronts with bilstein inserts. the old units had loads of red oil in them. i suspect that is what you are seeing. i didn't remove it all from mine and when i inserted the new ones it forced out some oil.
also, the new ones are filled with gas (?) not oil!
i don't think its anything to worry about. if you want to check, lift the front of the car, remove a wheel, drop the top of the strut (undo large nut), and see if there is alot of resistance in the insert (try and depress the shaft).
or have i completely got the wrong end here? you haven't installed yet have you?!!
dooh, (see avatar) then i can't help
but they are gas(?) so probably nothing to worry about.
