Rislone DEF Treatment AdBlue System Additive

Use When You Notice…

• SCR or DEF warning light on the dashboard — crystallisation may be blocking DEF flow; this adblue additive helps dissolve the blockage before costly sensor damage occurs.
• Vehicle entering limp mode on highway runs — restricted DEF delivery triggers engine derate; treatment restores normal dosing flow quickly.
• White crusty residue around the blue DEF filler cap — visible urea crystals confirm active crystallisation; use a double dose immediately.
• DEF pump sounding strained or irregular DEF consumption — partially blocked lines cause pump stress and inaccurate dosing readings.
• Vehicle failing PUC emission checks — a compromised SCR system raises NOx output and risks failure at the pollution check centre.

Key Benefits

• Crystal Dissolution: Breaks down biuret and cyanuric acid deposits inside DEF tanks and dosing lines, restoring full DEF flow rapidly.
• Limp Mode Prevention: Maintains correct DEF concentration so the ECU never triggers engine derate or SCR fault codes on long hauls.
• All-Season Performance: Conditions DEF fluid for reliable atomisation whether you are idling in 45 °C Nagpur heat or cold-starting in 2 °C Amritsar mornings.
• Ash-Free Formula: Introduces zero ash or harmful elements — your SCR catalyst and DPF remain fully protected and ISO 22241-compliant.
• Cost Avoidance: A single bottle is a fraction of the ₹25,000–₹1,50,000 workshop bill for SCR pump or injector replacement.

The Technology Inside

Rislone DEF Treatment contains a targeted blend of ash-free urea-compatible surfactants and crystal-modifying agents that penetrate and break apart the two most common crystallisation culprits in AdBlue systems: biuret and cyanuric acid. These deposits form when urea thermally degrades — accelerated by the high underbonnet temperatures common in Indian summer traffic and the freeze-thaw cycles of North India winters. The formula simultaneously conditions the AdBlue solution to restore its precise 32.5% urea concentration, ensuring the SCR dosing injector delivers the correct spray pattern for complete NOx conversion. Unlike generic DEF cleaners, this product is engineered to be completely non-reactive with SCR catalyst washcoat, so there is zero risk of poisoning the after-treatment system on your BS-VI vehicle.

Dosage & Coverage

Dose at 1 oz (approximately 30 ml) per 10 gallons (38 litres) of DEF as per the label chart — most Indian SUVs and light commercial vehicles carry a 15–20 litre DEF tank, so one treatment uses roughly 15–20 ml. Add directly to the DEF/AdBlue tank only — never to the diesel fuel tank. Use a double dose when heavy crystallisation is already visible, and repeat every second or third DEF top-up as a preventive measure.

Compatibility

Safe to use with

• All BS-VI (Euro 6) vehicles using ISO 22241-compliant AdBlue or DEF fluid.
• Heavy trucks and buses: Tata Prima, Ashok Leyland heavy commercial vehicles, Force Motors.
• SUVs and pickups: Mahindra TUV300+, Scorpio-N diesel, and all newer SCR-equipped diesel SUVs.
• Any SCR after-treatment system with a blue-capped DEF filler port.

Not suitable for

• Do not add to the diesel fuel tank or engine oil — DEF/AdBlue tank only.
• Cannot repair physical damage to SCR catalysts, NOx sensors, or DEF heater elements.
• Will not clear fault codes caused by failed sensors or wiring faults — mechanical diagnosis needed.

Why It Matters in India

Indian BS-VI commercial vehicles face some of the harshest DEF crystallisation conditions in the world: summer highway temperatures regularly push underbonnet heat above 60 °C, accelerating urea thermal degradation, while December mornings in Delhi, Chandigarh and Amritsar drop below 3 °C, causing DEF to partially freeze and concentrate. Long hauls on National Highways without adequate DEF system maintenance have left many Tata and Ashok Leyland truck operators stranded with limp mode lockouts, facing SCR repair bills that can cripple a small fleet's monthly budget. Regular use of this ad blue additive is the simplest, most affordable way to keep your SCR system compliant and your vehicle moving.

How To Use

1. Check your DEF tank capacity and calculate the correct dose using the bottle chart.
2. Pour the measured amount directly into the blue-capped DEF/AdBlue filler — not the diesel tank.
3. Use a double dose if white crystal residue is already visible around the filler cap or lines.
4. Top up with fresh AdBlue fluid to the normal level and drive as usual.

Safety Note: AdBlue is corrosive to skin and eyes — wear gloves and rinse any spillage immediately with water. Store the additive away from direct sunlight and out of reach of children.

Frequently Asked Questions

Can this clear existing SCR fault codes on my vehicle?

If the fault code is caused by DEF crystallisation blocking flow or distorting concentration readings, dissolving the crystals can allow the ECU to clear the code after a drive cycle. Codes from catalyst physical damage, failed NOx sensors, or wiring faults require mechanical repair at an authorised workshop.

How often should I dose to prevent crystal build-up?

As a preventive measure, add the treatment every second or third DEF top-up under normal conditions. If you operate in extreme heat (Rajasthan, Vidarbha summers) or cold (Delhi, Punjab winters), dose at every AdBlue fill for best protection.

Is this safe for DPF-equipped BS-VI vehicles?

Yes — the ash-free formula introduces no metallic compounds that could block or damage a Diesel Particulate Filter. It goes only into the DEF tank and never contacts the fuel or combustion system.

Will it help my vehicle pass a PUC emission test?

A fully functioning SCR system is essential for low NOx output, and restoring correct DEF dosing flow directly improves NOx conversion efficiency. If your PUC failure is SCR-related, this adblue anti crystallisation treatment is the right first step before spending on workshop repairs.

Is Cash on Delivery available and how fast is delivery?
