NOTE: If your SCR already has signs of crystal buildup (warning lights, limp mode, reduced power and fuel efficiency), we recommended using Rislone DEF CRYSTAL CLEAN™ Diesel DEF & SCR Emissions System Cleaner before moving to a maintenance schedule with this product.

Rislone Diesel DEF Treatment is a product that 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.

In short, Rislone Diesel DEF Treatment is an anti-crystallization solution that is used every time you fill your DEF/AdBlue tank. It’s a smart and affordable insurance policy against future SCR and DEF repairs.

Main benefits:

• Improves diesel exhaust fluid and avoids costly SCR / DEF system repairs.
• Regular use every time refilling the DEF / AdBlue tank works to prevent the white crystallization deposits from occurring.
• Protects the tank, pump, heater, sender, lines, injector and mixer.
• 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.
