Default Ducted Fan fuel

Got a question, I'm in the process of starting up a YS61RE AR motor that hasn't been started in 3 to 5 years. Its very smooth in turn over due to the fact that it was removed of any residue fuel and oiled. I don't have any YS20/20 fuel that I normally used BUT I do have some ducted fan fuel, 23% syn/cas and 10% nitro. I don't think this will hurt but just wanted to pose the question for some feedback. BTW, I don't intend to use this as a normal running fuel.

Castor oil can swell the diaphragm and plunger giving you problems in the future.

Castor oil doesn't swell the diaphragm. I have ran castor oil in YS's for years and years without hurting anything. The diaphragm is made of silicone, the same stuff that the fuel lines are made of.
Petroleum based afterun oils will swell the silicone parts.
