radiator leak
I agree. Where I live, -32F (50/50 mixture) does not assure enough
protection. I usually use about 60/40 myself for the very reasons you cite. I believe that the mixture "bottoms out" at around -84 degrees F at 70/30. This is from memory so may not be 100% correct. I am sure others who know for sure will correct this if it is wrong.
