There are many reports of Premix Antifreeze either freezing or slushing up in this unusually cold.

PLEASE check your cooling systems and use a tester to see what value you really have.
 
It is advertised as 50/50 which should be good for 30 below. But of course it all depends on what else is in the system.
 
Buying any premix is like buying light beer you are paying the producer for tap water. When I had my Turbo Buick I was advised to use Anti Freeze undeluted and distilled water (no minerals). I now do this with all my keeper cars.
 
YES on distilled water, also for battery use.

Still no certainty on how the premix situation evolved. Might have been a mismix at the bottling plant, or might be a different situation in barrel and tote delivery.

Don't really much matter how the problem developed, what matters is what's in your cooling system. Hydrometers and refractometers are both cheap.
