It prevents harmful white crystalline deposits in the SCR system, protecting critical components like the tank, pump, and injector. Compatible with all UREA AdBlue fluids and safe for new vehicle warranties, it’s especially effective for diesel vehicles frequently driven at low speeds or with frequent stops, helping avoid expensive repairs and maintain optimal engine performance. ## Description Accumulation of harmful white crystalline deposits within the Selective Catalytic Reduction (SCR) Diesel Exhaust Fluid (DEF) system can lead to expensive repairs. It is important to take all possible measures to prevent their formation. Beyond the financial burden, these deposits can reduce engine performance, increase fuel consumption, and potentially render the vehicle or machinery inoperative. RISLONE® DIESEL DEF TREATMENT is an anti- crystallization solution that is used every time filling the DEF / AdBlue® tank. INSTRUCTIONS: Measure required amount per dosage chart below and pour directly into DEF tank or into DEF bottle / cube when refilling tank. Light Truck or Mid-Size to Large SUV—4 ounces; Car or Small SUV—2 ounces; Medium and Heavy Duty Diesel Trucks—8 ounces Equipment & Machinery—8 ounces per every 10 gallons; Cube (2-1/2 gallon)—2 ounces. Only add to DEF or AdBlue Fluid, do not add to diesel fuel. ## Features - RISLONE DIESEL DEF TREATMENT is an anti- crystallization solution that is used every time filling the DEF / AdBlue tank. - Improves diesel exhaust fluid and avoids costly SCR / DEF system repairs; protects the tank, pump, heater, sender, lines, injector and mixer. - Regular use every time refilling the DEF / AdBlue tank works to prevent the white crystallization deposits from occurring. - Works with all UREA AdBlue DEF diesel exhaust fluids and will not void manufacturer’s new vehicle warranty. - Excellent for diesel vehicles driven regularly at slow speeds, low loads, short durations or make frequent stops as these are more prone to having the problem of crystallization deposit build up in the SCR system. ## Technical Specifications | Specification | Value | |---------------|-------| | Manufacturer | Bar's Products | | Brand | Rislone | | Model | DEF Treatment | | Package Dimensions | 25.91 x 17.4 x 10.21 cm; 1.8 kg | | Item model number | 4780-6PK | | Manufacturer part number | 4780-6PK | | Item Weight | 1.8 kg | ## Images ![Rislone Diesel DEF Treatment, 8 oz (Pack of 6) - Image 1](https://m.media-amazon.com/images/I/81Rk9FAWpFL.jpg) ![Rislone Diesel DEF Treatment, 8 oz (Pack of 6) - Image 2](https://m.media-amazon.com/images/I/61NmdchKjVL.jpg) ![Rislone Diesel DEF Treatment, 8 oz (Pack of 6) - Image 3](https://m.media-amazon.com/images/I/61i3F96opbL.jpg) ![Rislone Diesel DEF Treatment, 8 oz (Pack of 6) - Image 4](https://m.media-amazon.com/images/I/61NfYPmpTwL.jpg) ![Rislone Diesel DEF Treatment, 8 oz (Pack of 6) - Image 5](https://m.media-amazon.com/images/I/61-HPJ1BbTL.jpg) ## Available Options This product comes in different **Size** options. ## Frequently Bought Together - Rislone Diesel DEF Treatment, 8 oz (Pack of 6) - Rislone DEF Crystal Clean™ Diesel DEF & SCR Emissions System Cleaner, 11.8 oz - Rislone® DPF Clean™ Diesel DPF, Exhaust & Emissions System Cleaner, 16.9 oz, 4-Pack --- ## 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.sk/products/667047920-rislone-diesel-def-treatment-8-oz-pack-of-6](https://www.desertcart.sk/products/667047920-rislone-diesel-def-treatment-8-oz-pack-of-6) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-08-17*
