Webb28 sep. 2016 · A normal 50:50 mix of propylene glycol provides a protection level that will allow an engine to operate at -26°F (-32°C). That means that no ice crystals will form in the coolant till the temperature drops below -26°F (-32°C). This is referred to as the freezing point of the anti-freeze. WebbProper Use Of Propylene Glycol Choosing the Proper Glycol An inhibited propylene glycol such as “DowFrost” is best. DowFrost contains special corrosion inhibitors for low system maintenance and better heat transfer compared to other glycols. It also has a longer fluid life, up to 20 years in some cases.
