Rislone DEF Treatment AdBlue System Additive

Use When You Notice…

• SCR or DEF warning light on the dashboard — crystallisation blocks DEF flow and triggers fault codes; this adblue additive dissolves those deposits before limp mode sets in.
• Vehicle entering limp mode on the highway — a classic sign of DEF system restriction caused by urea crystal build-up inside the pump or injector.
• White crusty residue around the blue DEF filler cap — visible crystallisation outside means heavier deposits are forming inside the lines and tank.
• Irregular or unusually high DEF consumption — a partially blocked injector causes incorrect dosing; treatment restores proper metering and efficiency.
• DEF pump sounding strained or noisy — deposit restriction increases pump load; clearing crystals reduces stress and extends pump life significantly.

Key Benefits

• Dissolves Urea Crystals Fast: Breaks down biuret and cyanuric acid deposits throughout the full SCR circuit, restoring normal DEF liquid flow without flushing.
• Prevents Limp Mode: Clearing blockages before they trigger SCR fault codes keeps your vehicle moving — especially critical on long highway runs in India.
• Extreme-Climate Stable: Conditions the AdBlue solution to perform correctly whether you are idling in Nagpur heat or cold-starting in Chandigarh in January.
• Saves Expensive Repairs: SCR component replacement costs ₹25,000–₹1,50,000; regular DEF treatment is genuinely cheap insurance.
• Ash-Free & ISO-Safe: Contains zero ash, phosphorus, or residue-forming compounds — your SCR catalyst and DPF remain fully protected.

The Technology Inside

This adblue anti crystallisation formula contains specially selected urea-compatible surfactants and dispersants that penetrate and break apart the crystalline lattice structures formed when AdBlue degrades — primarily biuret and cyanuric acid deposits that standard DEF top-ups cannot dissolve. The chemistry works by lowering the surface tension of the liquid around crystal formations, allowing the urea solution to re-solubilise deposits and carry them safely through the system. Unlike solvent-based alternatives, the formula introduces no sulphated ash or metallic compounds that could poison the SCR catalyst or block the diesel particulate filter. It also conditions the AdBlue concentration, helping onboard sensors read correct DEF quality after treatment. The result is a restored, fully functioning SCR after-treatment system — without a workshop visit.

Dosage & Coverage

Dose at approximately 30 ml per 38 litres of DEF fluid — refer to the label chart for your exact tank size. Add directly into the blue DEF/AdBlue filler cap only; never add to the diesel fuel tank or engine oil. Use a double dose when heavy crystallisation deposits are already present, then return to the standard preventive dose every second or third DEF top-up.

Compatibility

Safe to use with

• All BS-VI (Euro 6) diesel vehicles using ISO 22241-compliant AdBlue or DEF fluid.
• Commercial trucks and buses — Tata Prima, Ashok Leyland heavy vehicles, Force Motors fleet vehicles.
• Passenger SUVs and MUVs with SCR systems — Mahindra TUV300+, Scorpio-N diesel, and similar.
• All SCR after-treatment systems including those paired with a diesel particulate filter (DPF-safe).

Not suitable for

• Do not add to the diesel fuel tank or engine oil — DEF/AdBlue tank only.
• Cannot repair physically damaged SCR catalysts, failed NOx sensors, or broken DEF pump motors.
• Not a substitute for quality ISO 22241-grade AdBlue fluid.

Why It Matters in India

Indian BS-VI commercial vehicles face a uniquely harsh combination: scorching highway temperatures that accelerate urea degradation, dusty conditions that contaminate DEF filler points, and freezing North India winters that stress the entire SCR circuit. On routes like Delhi–Mumbai or Amritsar–Jammu, a DEF system fault means the vehicle enters limp mode far from a service centre. Your DEF system is one of the most expensive assemblies on a modern BS-VI truck or SUV — protecting it with a regular ad blue additive treatment is far cheaper than an SCR replacement bill.

How To Use

1. Check your DEF tank capacity and refer to the dosage chart printed on the bottle label.
2. Pour the measured amount directly into the blue DEF/AdBlue filler — not the diesel filler.
3. Use a double dose if white crystal deposits or SCR warning lights are already present.
4. Top up with fresh ISO 22241 AdBlue as needed, then drive normally to allow the additive to circulate.

Safety Note: AdBlue is non-flammable but corrosive to metals and paintwork — wipe any spills immediately with water. Store the bottle below 30°C and away from direct sunlight.

Frequently Asked Questions

Can this product clear existing SCR fault codes?

If the fault code is caused by DEF crystallisation blocking flow or degrading concentration readings, dissolving the crystals often clears the code once the vehicle completes a drive cycle. Fault codes from physically damaged catalysts, failed NOx sensors, or broken pump motors require mechanical repair at a service centre.

How often should I dose to prevent adblue crystallisation?

As a preventive measure, add one dose every second or third DEF top-up under normal conditions. If you operate in extreme heat (above 40°C) or cold North India winters, treat every DEF fill for continuous protection.

Is this safe for my Tata or Ashok Leyland BS-VI truck?

Yes — the formula is ash-free and compatible with all ISO 22241-compliant SCR systems fitted to Indian BS-VI commercial vehicles including Tata Prima, Ashok Leyland, and Mahindra diesel models. It will not affect your DPF or SCR catalyst warranty chemistry.

Is Cash on Delivery available, and how fast is delivery?

Yes, COD is available across India and delivery is free nationwide. Most orders reach metro cities within 2–4 business days; remote locations may take slightly longer.

Will this help my vehicle pass a PUC emission test?

A fully functioning SCR system reduces NOx emissions as designed, which supports cleaner exhaust output. Restoring proper DEF dosing by clearing crystallisation ensures your SCR catalyst operates at full efficiency — contributing to compliant emissions under PUC testing.
