Designed for up to 25 gallons of DEF, it ensures consistent fluidity and sensor accuracy, reducing maintenance costs and improving diesel engine efficiency even in extreme cold. ## Description NuDEF: A Solution to DEF Crystallization To address these challenges, NuDEF offers a reliable solution. NuDEF is an additive designed to prevent the freezing and crystallization of DEF, thus maintaining the fluidity and effectiveness of DEF even in cold environments. Here?s how NuDEF enhances DEF performance: -Freezing Point Reduction: NuDEF lowers the freezing point of DEF, ensuring that it remains liquid at temperatures well below the typical freezing point of standard DEF solutions. -Prevents Crystallization: By inhibiting crystallization, NuDEF helps maintain a clear path in injectors and filters, ensuring consistent delivery and optimal SCR performance. -Enhanced Sensor Accuracy: With fewer crystallization issues, sensors operate more reliably, maintaining correct DEF dosing and efficient NOx reduction. Review: Fonctionne très bien Review: 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. ## Features - Helps prevent DEF crystallization - Lowers freezing point of DEF - Protects SCR system DEF tank, pump & injector - Treats up to 25 gallons of DEF ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0D5ZK5FX4 | | Brand | NuDEF | | Customer Reviews | 4.6 4.6 out of 5 stars (233) | | Date First Available | 9 June 2024 | | Item Weight | 290 g | | Item model number | 197644138449 | | Manufacturer | NuDEF | | Manufacturer Part Number | 197644138449 | | Model | NuDEF | | Product Dimensions | 5.08 x 5.08 x 16.51 cm; 290 g | ## Images ![Diesel Exhaust Fluid Additive & Stabilizer - Image 1](https://m.media-amazon.com/images/I/71yUFCKbo-L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by A***R on 25 November 2025* Fonctionne très bien ### ⭐⭐⭐⭐⭐ Review *by S***D on 21 August 2025* If you drive a diesel that requires DEF you need this product now!

This year we were having a really cold winter and I was getting alarms about emissions problems. I read it could be due to the DEF freezing. I believed that was my issue so I purchased this product. I can say I have not had a single issue after I have added the product to the def. And for the record we have had several single digit days. It sucks we have to buy another product to keep our trucks running but this product seems to do the job! I’ll use next winter to avoid any problems. ## Frequently Bought Together - NüDEF Diesel Exhaust Fluid Anti-Crystal Treatment - Treats 25 Gallons - DEF Additive & Stabilizer - Archoil Diesel Fuel System Kit - AR6500 Diesel Treatment (40 oz) + AR6400-D Diesel Fuel System Cleaner - Rislone 4780 Diesel DEF Treatment | Prevents AdBlue/DEF Fluid Crystallization, 8 oz --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.in/products/679452017-diesel-exhaust-fluid-additive-and-stabilizer](https://www.desertcart.in/products/679452017-diesel-exhaust-fluid-additive-and-stabilizer) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-05-24*
