You know, I was curious about adding castor oil to my fuel as well. I don't know where to get Wildcat fuel here on the West Coast (Southern California) I ussually fly Power Master 15% Nitro and I add about 3 ounces of Sig Castor too each gallon of fuel. This is just for my regular sport engines. I add about an ounce more to the Powermaster 15% 4 stroke fuel and so far I have had no problems burning up an engine but I don't know what to run in both my OS ducted fan engines if I cant get the Wildcat Jet A. Can I run the Powermaster with the increased Castor oil content in them or should I look for some other type of fuel.
Thanks Joe
