DESL EXHAUST FLUD 2.5GAL

Blue DEF is the best

Just as expected

Exactly what I needed, fast shipping. Thank You

Product purity is below standard. Good thing I tested it before using. Tried to contact seller and was told that the seller is fraudulently using invalid contact information. Contact Amazon and started a claim. The DEF Urea was tested at 31% but should be 32.5%. If you use this DEF, you'll damage your vehicle and void your vehicle's warranty.

I have had diesel pick-ups all my life. When I had to start adding DEF fluid, I figure they were all the same and I always went with the cheaper one. Turns out there is a difference. Stick with the Peak brand. It will save you money in the long run

These were delivered upside-down and leaked

Product performed as expected. Nothing special.

Same ISO as shown in owners manual.
