         This is for MoGas, not AvGas.

         As I understand it, the mix for MoGas changes with the local 
seasons. I don't think they change the mix for AvGas seasonally, but I 
could easily be mistaken.

         Being an experimentalist type, I would probably slowly warm up a 
small vented container of AvGas and carefully watch the level as I did so. 
The temperature at which the level started to change in the container would 
be the "redline" I would set for the tank temperature.
