Thanks Doug, helpful as always
So, if I've understood correctly despite only extracting 25ml it still took 180ml to refill, and as the total capacity is 180ml the 25ml you were able remove was more or less the only oil left in there after 57,000 miles?
That would make it a total loss lubrication system, all be it a very slow one
I also found this guide that supports your words.
