It sounds good. I'm interested in learning what the cost will be and it would be nice if the shelf life was greater than the 18 months regular Blue DEF provides.
Shelf life? Fill at the truck stop $2.99 a gallon and always fresh, refill as needed.
That you get at the pump is never completely fresh. They just pour the new into the tank on top of the old and it all gets diluted. The old just keeps getting more diluted each time but never completely goes away. So you end up with multiple ages of DEF all mixed together.
Better or worse than the jug? Who can say?
The only places I've seen DEF at the pump are higher volume truck stops so it stands to reason they turn it over pretty quickly, and it would pretty heavily dilute the older stuff I'd think.
When it comes to DEF I'm all about convenience. Since Costco started carrying Peak Blue, that's mostly what I use because I'm there every week. I have no issues with Walmart or Pump DEF, though - it's all the same stuff.
