Graham Phantom B-44 shipping question


I gotten conflicting opinions on this question. When one ships a Graham Phantom B-44 do you leave the damping fluid in or removed? If removed, how does one remove all dumping fluid and make sure that it is super clean without harming anything?

I have a graham 1.5 and try to replace the damping oil.  I have tried to order it in two website.  but i still didn't get it after 10 months.  Is there any replacement?  is 600K cst is the best?  Many thanks for your kind advise.

thank you very much.  But I don't whether 600K is good for graham or not.  thanks again
