Question Aquamist Water Injection in the Cold Winter Months

What's the proper setup for the Winter months in New England?
I dont want any freezing problems.
What are people using?
Is 50/50 water/methanol the best, even in winter, or is straight windshield washer the best, etc.?
The car will be tuned for 50/50 mix (year round). Will this be a problem?

While in CT I ran a 50/50 blend of denatured alcohol and distilled water w/o any issues w/freezing. Planning on running the same in CO.

50W/50M will see you through most winter, freezzing point of the mixture is -40C or 40F. Good for summer as well.

Check the alcohol type on the washer fluid before use it, it could contain ethanol instead of methaol. Aquamisy pump is nopt designed to run ethanol alcohol.

Do not use denatured alcohol because it contain mainly ethanol.

.
so what is the freezing point of the 50w/50m mix? 40 degrees above zero faranheit?? If so, what is it for pure meth as it gets down to the 20s faranheit in my area over winter time.

No, no. It's about -40f. You're good to go unless you live in northern Alaska.

Richard - is this advice based on the usage of only your pump? I've been running 50/50 denatured/distilled for almost 20,000 miles and through 2 winters thus far......but your statement has me curious. TIA!

Depending on the age of the pump, we have changed the seals and valve materials in Dec 2005, by March 2006, most pumps will be equipped with the new seal and more resistance to high concentration of ethanol - depending on the astock rotation of the vendor, some older seal may be distributed beyond March. I still prefered people not to use ethanol based mix. If you have any problem, please contact me for the new seal.

Thanks for the info Richard. I'd take you up on your very generous offer but I don't run an Aquamist system....hence my asking if the problem was specific to your pump. Mine utilizes a Shur-Flo. I'll keep an eye on the pump seals though. Thx again for the response.

I believe Shurflo has many seals and valves material variations, since you have been running denatured alcohol for two years without any problems, I assumed you have the correct pump materials in your system. It is always worth checking every 6 months for signs of small leaks.
