I am worried about coolant freezing in my cold saw, accidentally.
This is northern Illinois, so temperatures of 0 to -5F are not uncommon. How can I make soluble oil (20 or 30:1 ratio) a little bit more freeze proof. Is there something that I can add to it, like ethylene glycol, without the risk of ruining the pump, seals, bearings, or anything else. My garage is attached, so it rarely gets below freezing, but when that happens, I do not want to be caught.
