It's my understanding that we are only supposed to use a 50-50 water to coolant
mix in our Wasserboxers. According to the back of the jug and my little tester
dohickey ---- this resulting mix is good to -30 celsius or -22 fahrenheit. What
do listees in cold climes use?? Here in Toronto it did get down to -30 celsisu
last year --- but no colder ---- and I'm wondering if I should be increasing my
mix to be on the safe side --- or is there a reason not to do this???

Thanks,
