Rislone 4780 Diesel DEF Treatment | Prevents AdBlue/DEF Fluid Crystallization, 8 oz

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.
