Methanol/Water Mix Freezing points.. Just some information

[AudiSportB5S4]

I was thinking with the winter in full swing around the Northeast and wherever else you live and it's COLD out, if you run w/m I was curious as to what the freezing point would be..

Found this post made by a Devil's Own employee on their website.

Methanol/Water Freezing Point Info

Just sharing some information that's all! Drive safe.

ran mine all winter long 50/50 mix no issues what so ever and we had some really cold days last winter up here in Toronto Canada thanks for the info good to know

for the lazy

Take your Methanol \ Water Mixtures Conctrate to determen the freezing point of your mixture. Winter is here and you should make sure your not going to have a freezzig problem.


Methanol (METHYL ALCOHOL) Conc.
Vol.% ---Freezing Point,F ---Flash Point,F


0----------32f--------No Flash
13---------20f --------130f
24---------0f ---------110f
35---------15f---------95f
46 --------40f---------85f
56---------65f---------75f
66---------95f---------70f
75---------115f--------60f
83---------125f--------55f
92---------130f--------55f
100--------144f--------55f

Other tid bits
Boiling Point: 147F,64C
Melting/Freezing Point: : -144F,-98C
Vapor Pressure: 760 Vapor Density: 1.1
Specific Gravity: 0.8

50/50 mix good for about -50*

By flash point what does he mean?

By flash point what does he mean?

Flash point is temperature which the flammable liquids pressures begin to build to the point of starting combustion.. So kaboom will happen after that temp!

Eh, kind of. Its the temperature at which the vapor can ignite. Meaning, if you had a sealed bottle of 100% methanol its perfectly fine and won't combust at or above 55 degrees F as indicated by the flash point. Or, lets take 50/50 mix with a flash point of about 80F. Your engine bay will definitely see those temps, but you don't have to worry so long as 1. You don't have leaks and 2. there is not ignition (spark) source in close proximity to the vapor leak.

Just don't want to freak people out and discourage anyone from using methanol

was gonna say.. i have run 50/50 mix in 80*.. and i havent blown up yet..

i always did dance the line....

Haha wow, I didn't even look how low those numbers were for flash points :-p. I ran my meth setup in the heat and all summer long didn't have any problems.
