Compatible with all UREA AdBlue fluids and safe for manufacturer warranties, it prevents costly repairs by maintaining optimal DEF fluid performance, especially for vehicles prone to crystallization due to stop-and-go or low-load driving. ## 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.
