No Crystal's forming yet.
Seems to work as advertised. I see no crystals forming in the DEF

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.

No freezing or crystallization
It works … I guess ! All I know is I have no crystallization or freezing of the DEF and I live at 7000 ft in the Eastern Sierra where the temperature gets down in the low teens .

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.

HUGE help with my DEF System
I've been frustrated with my truck's DEF system for some time now...It seems that DEF fluid is wildly unstable (something they really don't tell you when buying a truck) and as a result, I've experienced my share of DEF system failures. Even when adding DEF fluid as recommended, the volatility of DEF fluid creates a seemingly perfect environment for DEF systems to fail when driving a diesel-powered truck like mine.A friend suggested I try using NuDEF...I was skeptical but figured I had nothing to lose. The dreaded DEF system light had returned again and before making yet another trip to my local dealership to once again be charged a fortune for a repair, I tried it. Wow! After mixing in NuDEF with my DEF fluid and driving for a short period of time, my DEF system light went off and my truck seemed to be a bit...happier! It's now been a few weeks and I have yet to see the DEF system light return and my truck has been performing perfectly. Thanks, NuDEF...You DEFinitely (see what I did there) have a customer for life!

Preventive maintenance
3 of my DEF truck systems have had some sort of failures. I was always worried that DEF would dry out flake and plug up the system. Hoping this product keeps my units trouble free

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.

It’s an additive for def fluid
I got this for the stupid def fluid in my diesel. I don’t drive it in the winter because i like it and we use a ton of salt here. I dunno if it works I’ve started it a few times no issues only time will really tell.
