Can't tell you the exact point at which Avgas freezes but i know that the ig Continentals had problems below -23c. Continental Aircraft ESB M73-3R3 advise a mix of Isopropryl alcohol of 1% by Vol

Didn't know the answer before this question was posted, but found out the freezing point of 100LL is -58C.

See this website:. .<a href="http://www.purvisbros.com/aviation/avgspec.htm" target="_blank">www.purvisbros.com/aviation/avgspec.htm</a>

It's amazing what you can find on the internet.

It's amazing how much time one can waste on the internet...Yes, honey, I'll be off in a minute!

Avgas itself may freeze at a very low temperature but any water in solution or fuel additives may cause problems well before -5o ish
