Review: 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.
Review: 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!

### ⭐⭐⭐⭐⭐ Keep the DEF light off.
*by B***N on August 11, 2025*

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!
