[Closed] Magura Thor oil levels.

I have a 2010 Thor AM 140 which I am in the middle of stripping down. Lower leg service is pretty straightforward, easy as a Rockshox, and having got that far I have had a little prod round and discovered an oil leak on the damper side, which I am guessing will be an o ring. A bit of careful exploration shows me that disassembly us not the impossible art Magura et Al would have you believe, and once I find a 28mm socket it'll soon be out. Thing is, I have no idea how much oil to put back in the damper leg. I'm guessing it'll be about 150 ml, but would love to know the proper amount before I end up simply using trial and error. Anyone know how much is in there? I can't measure how much comes out as most if it is on the workbench and the footwell of my car.....
