Prevent costly urea crystallization
If you drive a diesel that requires DEF you need this product now! It will save you hundreds to thousands of $$ because it prevents urea nidus crystals from forming. Once you have urea crystallization in your DEF tank it will always continue to be a problem. NuDEF breaks down the urea crystals that form. This reduces the use of DEF your vehicle is forced to cycle through by the sensors that monitor urea crystal formation. It saves you money on DEF and fuel. And it protects your vehicle.

I did not know this existed. I tried it and am a believer. No DEF issues since.

Keep the DEF light off.
Before, I was getting an error warning saying the DEF quality was insufficient. No restarts after 250 miles. So I purchased a code scanner and reset the code. Error came on again after 100 miles or so.. I tried a local repair shop and they said “dealer only repair” wouldn’t touch it. Here’s the Great News! I purchased this product and have had No problems since. This bottle has saved me from expensive repair bills. Thanks!

I am giving it a try.
You know, I don't know if this stuff works or not, but I can see the DEF crystals around my DEF tank inlet. If this stuff does what the manufacturer and the other reviews say it will, it's worth the cost. I have a 2015 and 2024 Ram 2500, both with the 6.7L diesels, so I started putting this in both of their DEF tanks when I fill up. Time will tell.

Stuff really works
Was getting the P207F code. Sucked the all old DEF out of the truck best I could and refilled with blue def platinum along with a dose of nudef. Took about 50 miles but cleared up the code.

I really cannot tell any difference.
This might work or this might not? I followed the directions and honestly I can’t tell any difference yet. I’ll give it a honest try until the bottle empty and then I’ll make my final decision.
