Does anyone knows the exact freezing point of Avgas (100LL) ?

I found that Jet A-1 freezes at −47 °C / −53 °F (wikipedia), but didn't manage to find any info on Avgas.

  • $\begingroup$ Are you asking for some particular purpose (like you're designing a system where you need to keep avgas from freezing), or out of curiosity? $\endgroup$ – Terran Swett May 10 '17 at 22:49

    $\begingroup$ Avgas, which is gasoline, must sustain -58°C, this table from ACRP Overview of Airport Fueling Operations $\endgroup$ – mins May 11 '17 at 8:27

ExxonMobil China says their Avgas 100LL will not freeze above -58°C.

The 'typical' freezing temperature is not given, but I would expect we'd be more interested in the maximum freezing temperature.
