Some guys have them tested, and the result is 25% is the max nitro you can have here in our part of the world for a .12 engine. My opinion, maybe 20% is the best percentage...
more nitro does not mean less oil. the rise in operating temperature is not from decrease in oil, it is from the increase in % of nitro.
one bit of warning however is when nitro content exceeds 40-50%. castor oil is actually insoluable in nitromethane. castor oil will separate out of solution (with nitro of 40-50% or higher) unless a co-solvent is added.
