Premium Quality You Can Trust
There’s cheap stuff everywhere you look. Not all products are created equal. However you want to phrase it, it’s the truth.
Rislone’s DEF products are produced with the highest standards in mind to solve real world problems diesel owners are experiencing.
Each lot is rigorously tested to ensure that it meets or exceeds industry specifications. Utilizing nothing but premium-grade chemicals, Rislone’s DEF products ensure optimal performance and compatibility with all SCR (Selective Catalytic Reduction) systems in diesel engines. This commitment to quality helps prevent costly repairs and enhances the longevity of your diesel.
Rislone DEF Products: Quick Overview
Rislone has made a name for itself in the diesel market with three innovative products that focus on DEF pathway and DPF cleaning/maintenance:
- DEF Crystal Clean® Diesel DEF & SCR Emissions System Cleaner – This is a cleaning step that most customers use only once every 3-4 months. This solution cleans the entire SCR system by dissolving the white crystal deposits that form in the tank, pump, heater, sender, lines, injector, decomposition tube/reactor and mixer. These deposits can interfere with the normal operation of the SCR emissions system and engine, increasing fuel consumption and reducing engine power. This reduced power can lead to operating in limp mode where the vehicle will drive slowly, or become undrivable. If you’ve never done any maintenance on your SCR, start here. Add to DEF tank.
- Diesel DEF Treatment – inhibits the accumulation of harmful white deposits within the Selective Catalytic Reduction (SCR) and Diesel Exhaust Fluid (DEF) system that 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. This is a maintenance step. Use after a thorough cleaning with DEF Crystal Clean® Diesel DEF & SCR Emissions System Cleaner (above). Add to DEF fluid before installing into vehicle.
- DPF Clean®Diesel DPF Exhaust Emissions Cleaner – Your single-bottle solution to help your diesel vehicle restore lost power/performance, unclog a blocked DPF, turn off check engine light, and clear P242F and similar OBD codes. Your easy button for most DPF issues. Use once every 5,000 miles to keep your diesel running at its best, extend DPF life, and reduce regeneration cycles. Features money back guarantee. Add to diesel fuel tank.
