Don’t trust your $$$$ diesel to a lower quality product. Easy to use highest test rating and good value in bulk.

Great product , great value. I love the fact that the included nozzle makes it super easy to add the fluid to the DEF tank.

It does its job!

It does it's job

[This review was collected as part of a promotion.] It is essential to have this quality product as it is used for School Bus transportation. As a smart an informed shopper, Walmart provides this quality of a product at a price offered by no other business.

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 ;)

So easy to fill your DEF on your own! It’s the exact same brand they use for European vehicles. I confirmed this with my garage. So instead of paying them $90 to fill it, I do it myself for much less! Check with your mechanic FIRST and make sure it’s what they use!!!

Be careful lifting the box, using the handle on top. The cardboard rips/breaks easily. As a result, I dropped the box and it made a mess. If it were usable, it would have been nice because this one has the accompanying funnel for pouring it into the car’s reservoir.

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.

Well, it's DEF fluid... I personally don't have any use for it but I'm regulated to have it. I need the truck I have that requires it so I can pull the equipment to build the houses for the people that don't want me to drive the truck or or cut the trees to build their houses, etc, etc, etc. Sams got it to me quick
