DEF fluid brand

My DEF of choice. I use it in the first coach, in the current coach and in our Towed GMC (nearly 100,000 miles between the coaches and the GMC). Wally World turns it over pretty quickly so it is always fresh. I also hear rumors that there are only one or two DEF production facilities, so it is all the same stuff, anyway.

No matter what the marketing name, packaging design or price, if it displays the American Petroleum Institute logo then the manufacturer has paid fees and is subject to third party lab tests and audits to prove that the fluid meets ISO 22241 standard. You can lookup the ISO standard for yourself to verify that the required formula does not have much wiggle room for it to contain anything other than urea and water. So while it is conceivable that some brand might have a tiny, trace amount of minerals/metals in addition to the 32.5% Urea and 67.5% pure water, as a practical matter it is not likely that any manufacturer's DEF performs better or worse than another.
In short, until I see some proof of a meaningful difference between brands of DEF I’m going to buy whatever is cheapest or most convenient

My thoughts exactly.

Walmart brand 95% of the time in my Chevy trucks since 2015…no issues.
I hate it when they are out of Supertech in the store and I have to pay for another brand.

Walmart Super Tech is what I use and no problems. Was using Blue or Blue Platinum, opened one and the seal was broken. Took the DEF back to Walmart and bought a tester from Amazon. The Super Tech is the same chemical. It has not failed me and I test most jugs that I buy. Have not found a bad one and have not had an issue.

OK so it seems so far I’ll be the lone voice for using bulk DEF from truck stops. Have used it exclusively since DEF came out in all my coaches, pick ups, heavy trucks and equipment. The boxes are a mess and double the cost.

I'm guessing it's because the box with the jugs in it was dropped or shocked, causing the contents to surge up and pop the safety seal. But, whatever the case, I don't want to be using jugs with the safety seal broken.

The 'seal' is just a thin layer of foam. I have opened several and found the seal loose or stuck in the inside of the lid. My Milo's Iced Tea and and my 'Simply Lemonade' have real 'tamper-proof' safety seals, Walmart DEF does not. Stiil I always buy the Walmart brand

I use pump more than the walmart Def , just depends on where I'm at.
Pump price I have been paying is $4 +/- walmart last buy was bout $9 for 2.5 gallons , so walmart is cheaper by a buck, just not convenient to get 10 gallons.

Usually comes down to convenience. Walmart, pump, where ever we are.
I carry a couple of the Blue jugs. If pumps aren’t busy, I’ll fill the jugs.
On the Classics, it’s more of a pita to try and fill at the pump.
