BlueDEF Diesel Exhaust Fluid (2.5 gal.)

Works and does not spill as much as the cheaper one.

Works and quality container

walmart.com

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

a necessity

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

Quality of SAMs DEF has been consistently good.

Always in stock when ordering and good prices

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

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

Bad packaging

The ease of use for this is great owning two diesel vehicles. Easy poor nozzle for convenience

Best def

They brought it out. It had a hole in the be careful what you buy. I paid for this and never was able to use it. It ran out before I got home all over my truck that I had to wash.

the blue Def works great Walmart carries it and it is about the cheapest place if I have to buy it in any other store it is double the price and if I cannot find the blue DEF I am forced to use no name brands and I have nothing but problems check engine light comes on I will get a 75 mi to 15 mile an hour see dealer immediately as soon as I put the blue d e f back in all my problems go away.
