Actually that has an additive that stops allot of crystallization. A few people on YouTube have done tests on it. I run it and decode the numbers to get the freshest I can, plus Menards runs 11% rebate.I get DEF Blue Platinum jugs from HD. Maybe a waste of money for "premium" DEF but the extra $5-6 a jug every few thousand miles isn't a big deal. I rather fill up with jugs at home so I never have my DEF cap and diesel cap off at the same time. Jugs also have serial numbers that you can decode and see when it was manufactured. The two that I just bought was made six weeks ago.
