Diesel fleet operators and farmers now have a new tool from Rislone to combat a common problem: crystal buildup in diesel exhaust fluid (DEF) systems.

The company has launched a super-concentrated version of its Diesel DEF Treatment, designed for larger-scale users who manage multiple diesel vehicles.This new product, called Rislone Diesel DEF Treatment Super Concentrate (part number 4782), comes in a 33-ounce bottle.

One bottle treats up to 55 gallons of DEF, and a case of six can handle a 330-gallon DEF tote. This bulk-treatment capability makes it simpler for fleets to add the protective formula each time DEF tanks are refilled.

According to Rislone, the concentrate uses the same base ingredients as its standard DEF treatment.

The formula works to keep DEF stable, stop crystals from forming, and help the vehicle’s selective catalytic reduction (SCR) system function properly.

Clay Parks, Rislone’s vice president of development, highlighted the practical benefit for larger operations. “Our concentrated formula makes it faster and more efficient to apply the treatment across a fleet of vehicles,” he stated.

Using the Super Concentrate regularly helps prevent white crystal deposits from developing throughout the DEF and SCR system – this includes the tank, pump, heater, lines, and injector.

Rislone points out that diesel vehicles making frequent stops, running at low speeds, carrying light loads, or being used for short trips are often most affected by these deposits.

If a diesel system already has heavy crystal buildup, indicated by warning lights or reduced power, Rislone advises first cleaning the system with its Rislone DEF Crystal Clean Diesel DEF & SCR Emissions System Cleaner (part number 4784).

The new Super Concentrate then serves as a preventative measure for ongoing use. This new treatment works with all urea DEF and AdBlue fluids and, Rislone assures, will not void new vehicle warranties.

Rislone’s American-made Diesel DEF Treatment Super Concentrate is now on shelves where auto parts are sold.

Those who run numerous diesel vehicles can use it to simplify the job of maintaining healthy emissions systems and, of course, meet emission standards set by their respective state.
