Rislone 4780 Diesel Exhaust Fluid Treatment is an 8 oz anti-crystallization additive designed to prevent white crystalline deposits in SCR DEF systems.

Recommended for regular use at every DEF refill, especially for vehicles with stop-and-go or low-load driving patterns.

## 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.
