It all depends on the mixture, where I live; the freeze point is -40C/F which means it's 50% methanol and 50% water. Minus 14F isn't a huge deal for most cars, it was -39 here a day ago and I still didn't have any issues with my S70. Of course at -39C you must plug your cars blockheater in or protect it from the cold just to be able to start it. I have seen brake hoses get bulges in extreme cold, but once again, -14F barely qualifies.boosted5cyl wrote:Weird....Its always frozen for me at some point (regardless of car) and when its on the edge of freezing in the tank it then freezes on the screen. Ive started to use the yellow stuff, has never frozen in either situation and its nice and viscous compared to the blue stuff.JRL wrote:Cheap "blue stuff" works just fine
Just baby your car when it is warming up, I have seen so many plastic and rubber pieces cracking causing coolant loss etc when a vehicle is driven hard cold.
