Nic,
I flushed and filled my clutch with baby oil about 6 or 7 months ago and it has worked just fine. Others have said that the baby oil is a little heavier weight than the Magura stuff but I haven't noticed it at all. Maybe that would show up more in a colder climate but with the heat here in AZ the baby oil works fine. Another plus is that the baby oil is only about $1.50 or less and you can flush and fill your clutch 4 or 5 times where the Magura oil is about $5 for about 4oz. And as Kelsow mentioned, it gives your bike a fresh powdery smell to boot :wink:
Regards,
