perfect I am in similar climate. How long have you been running like this ?
Since about the middle of October 2020, I found distilled water in the baby section at WALMART one day, a buck a gallon, I was planning on getting or building a distiller, but for a buck I don't even wanna think about it.

Looks like from what I can gather, The 32.5% urea/DEF mixture starts to crystallize and freeze at 12 degrees F.
It’s been 25 degrees in the mornings where im at in PA this week. Just trying to find out how much I can dilute DEF without worrying about it freezing. If anybody knows? Thanks
Don’t know how this post went from SFT to DEF but hey, I’m learning stuff lol

It’s a buck a gallon in PA too. I have a 2016 and love it so far. Waiting on delivery of a SFT engine tune. Thanks for all the info

The freezing is not important, Because My research indicates at around 22-24F the heater is engage and dis-engages around 34F...

I see. Didn’t know DEF had a heater but it makes sense. So if I run say 10-20% urea/DEF in my tank and it is frozen solid, it won’t cause any problems buy the time the heater thaws it? Or would you suggest staying with the off the shelf blend in the winter months? Thanks

Makes no difference I would probably stay right around a 10%. Urea and 90% distilled water and that's generally 3 gallons of distilled water and then 1 gallon of def retail. But there's nothing wrong with going 2 gallons of distilled and 1 gallon of def retail.
