I was a little worried about the Walmart DEF not having the ISO 22241 on the jug like the Peak does however after doing some research, (Walmart does have the API certified sticker) by law, if the fluid is called Diesel Exhaust Fluid, it must be ISO 22241 certified. I use the Peak except for a couple of truck stops in CO. I'm not a high mileage driver so the cost is not a factor for me to an extent. But long story short, the Walmart DEF meets ISO 22241 and should be fine.
On another note, you can order Mopar oil filters for $7 and change on their website and pick them up at the store. You can only buy 2 at a time however. The store price is $12.
