I had nothing but trouble with the -20 rated blue stuff at 14F and under in my 2016 cascadia.
I always stock up on “the purple stuff “ whenever I’m up in the northern plains. Avoiding the aggravation and safety concerns is worth the extra money. I’ve had the blue, -10 rated stuff freeze up on me above 15 degrees, too. I would think most companies would reimburse the cost of purchasing it at a truck stop, as long as you have a receipt.
I always reset the trip meter when I fuel. My fuel gauge is weird. Sometimes my trip meter will record 500 miles before it dips to half tank. But then it will drop rapidly in the next 200 miles. I usually fuel every day at about half or at the most 650 miles.

I’ve done this for over twenty years in my personal vehicles with no issue. One other thing, don’t buy the blue washer fluid down south in the winter. Go to a truck stop somewhere that actually has cold winters (Maine, Minnesota, etc.) Can easily find the blue stuff that’s good to -20.
