Dads, I am somewhat new (just over a year) to the hobby, but from what I understand the % is the nitro and the higher the nitro the lower the oil should be. You should actually run hotter on 30% in theory anyway.
I don't disagree but am not convinced either way. I've read enough posts for and against, my head is spinning and everyone sounds right in their own explanation. I probably need to contact a fuel company to find out the real answer.
