FYI....- 20 degree windshield washer fluid is 30% Methanol/70% Water...I sell it to all the Rental Car Agencies in my area.
Boost Juice is 49% Methanol/51% Water.
Straight Methanol is very dangerous - Very flammable stuff!
(I'm looking at a Snow kit for my Fusion Sport...Turbos love Meth Injection!)
