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 .

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

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!

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.

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.

Worked great on our DEF system that sat a year in our MB camper.

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.

Warning!!! Read all this first
Warning, read all labels first. Don’t do what I did and pour the whole bottle.Thankfully, I noticed before turning the truck knI did see another review that it messed up an engine.
