It does exactly what it is supposed to do, treats diesel exhaust. Having a bad day? Next time buy DEF from a German make auto dealer then next time you buy Peak Blue DEF and you will feel both rich and brilliant! The Peak Blue DEF is easy to use while filling the DEF tank using the flexible tube supplied with the fluid. It isn't much different from pouring wine in a box, though you won't feel better after drinking this stuff. That is an assumption - I haven't tried it ;)

Product arrived as scheduled and in somewhat good condition. Some of the boxes were damaged but the item inside was ok. I don't believe it was Walmart's fault as the product was shipped to me via Fed-X and I believe it was Fed-X that damaged the packaging. Otherwise product I ordered was what I received.

I searched around locally for the DEF fluid but the prices were higher for the same brand or comparable brand. It's great I just place the order from Walmart and they deliver for free right to my doorstep. I ordered three packages to get the free shipping. The package comes with a handy nozzle that fits in my Nissan diesel truck so filling the DEF reservoir is a snap.

We’ve been using this product in our 2018 Diesel SUV with no problems. It’s easy to add more

This is great for my truck and it’s the cheapest at Sam’s

bought for our diesel truck that can't survive without it

Always in stock when ordering and good prices

Leaked in the back of my truck heading out of town cleaning up my truck bed was a hassle

Clean fuel, more diesel engine efficiency and better for the environment.

Does what it's supposed to!
