DEF degrading?

[Mr. T]

I understand that DEF freezes at 12 degrees.
Our outside temp is projected to get down to 19.
How (if any) will this degrade the quality of the DEF?
Thanks!

Just cold temperatures doesn't affect the quality of DEF. Even if it freezes, it's fine when thawed out and it won't freeze unless it's below 12f for extended time.

It won't hurt it, but...

According to the "experts" there's a simple prevention...

Totally unnecessary. Experts
I've had my truck parked overnight while hunting in below 0° temps and never had a problem.

Below 0 degree temps is why the "experts" park their EV trucks at the headquarters in San Diego, California. They just write some stupid DEF recommendations for folks that actually live, work, use, and park diesel trucks out in the cold.

Also, realize that most manufacture of motor vehicles that use DEF have heaters installed in the DEF tank to thaw out the DEF. Remember also the engine does not use DEF it is the exhaust system that requires the use of DEF to meet the emission requirements.
