Oil thickens when it gets cold so I don't think I'd want to make the Caster in the mix all gummy nor would I want all that condensation in my fuel bottle when I pull it out of it's cold bath and into the heat. I think it was a good point too when someone said something about the tune changing halfway through the tank. From what I've heard sunlight is the worst enemy of nitro fuel, it breaks down the chemicals, not temp.
