Title: ??????????
Post by: Bootlegger on February 15, 2012, 04:00:45 PM

  I have some 10% Nitro 22% oil half and half, what do I need to do to use it in a Cox engine?
  Can I add castor, and how much do I need?
                Thanks Gil

Nope, you want to add Nitro to bring it up to 15%.  The oil content should be at least 18%.

   H^^   Thanks Larry, but I want to be sure that 11% castor with 11% synthetic is sufficent, or does it need to be all castor?
    Again thanks for your answer...

Half and Half is just fine.  And 22% is overkill.  I would add Nitro until you get to 18% oil or 15% Nitro, whichever comes first.
