Rislone Cat Complete

Use When You Notice…

• High HC/CO on your PUC certificate: A soot-laden cat cannot oxidise exhaust gases properly — this cleaner burns off deposits before your next test.
• Check-engine light with a P0420 code: Carbon buildup drops catalyst efficiency below the ECU threshold; cleaning often resolves the fault without a costly workshop visit.
• Sluggish acceleration and falling kmpl: A partially blocked converter creates back-pressure that robs power and increases fuel consumption — especially noticeable on Indian highways.
• Rough idle after city stop-go driving: Short urban trips never fully heat the cat, allowing soot to accumulate; Cat Complete safely regenerates it through normal driving.
• Rotten-egg smell from the exhaust: Sulphur deposits on catalyst surfaces produce this odour — a clear signal your cat needs attention.

Key Benefits

• Catalyst Carbon Removal: Dissolves stubborn soot layers inside your catalytic converter without any dismantling, restoring exhaust-gas conversion efficiency.
• Lower Tailpipe Emissions: Cleans injectors and combustion chambers simultaneously, reducing raw HC and CO output so your vehicle meets BS6 norms.
• PUC Test Confidence: Used over 2–3 tanks before your annual PUC renewal, it gives borderline vehicles a measurable edge at the emission check.
• Improved Fuel Economy: Reducing exhaust back-pressure and improving combustion efficiency directly translates to better kmpl in Indian city traffic.
• O2 Sensor Safe: Formulated to protect lambda and wideband O2 sensors — critical for BS6 closed-loop fuel management systems.

The Technology Inside

Rislone Cat Complete combines high-temperature fuel-system detergents with combustion-modifier chemistry that targets polyaromatic hydrocarbon deposits — the stubborn soot layer that forms on three-way catalyst substrates during low-speed city driving. As the treated fuel burns, active agents penetrate the catalyst's honeycomb washcoat and chemically loosen carbon bonds, allowing normal exhaust heat to finish the regeneration process. Simultaneously, PEA (polyether amine) detergents clean injector tips, intake ports and combustion chambers, reducing the unburnt fuel load that originally caused the deposit build-up. The result is a cleaner emission system working at its designed conversion efficiency — measurable at your next PUC test.

Dosage & Coverage

One 425 ml bottle treats one full fuel tank as directed on the label. For best PUC results, use across 2–3 consecutive tanks and include at least one sustained highway run of 30+ km at speeds above 80 km/h to bring the catalyst up to full regeneration temperature. For city-driven vehicles, repeat once every 20,000–25,000 km or before each annual PUC renewal.

Compatibility

Safe to use with

• All petrol engines fitted with three-way catalytic converters and oxygen sensors
• BS6 emission systems (April 2020 onwards)
• E10 and E20 ethanol-blend petrol — fully ethanol-blend safe
• Naturally aspirated and turbocharged petrol engines
• Maruti Suzuki, Hyundai, Tata, Honda, Toyota, Kia, MG and other popular Indian brands

Not suitable for

• Physically damaged, melted or structurally collapsed catalytic converters — cleaning cannot repair substrate damage
• Diesel engines — use Rislone Hy-per Diesel Complete for diesel fuel systems
• Two-stroke engines

Why It Matters in India

India's mandatory BS6 norms and PUC certificate system mean a degraded catalyst can ground your vehicle or attract fines. Stop-go traffic in cities like Delhi, Mumbai and Bengaluru keeps exhaust temperatures low, accelerating soot build-up inside the converter. Variable petrol quality and widespread E10 adoption since April 2023 add extra deposit-forming stress to the fuel system. Cat Complete is specifically suited to these conditions — clearing accumulated carbon so your BS6 catalyst performs as intended, whether you drive a Maruti Baleno, Hyundai i20, Tata Nexon or Honda City.

How To Use

1. Add the full 425 ml bottle directly into the fuel tank before filling.
2. Fill the tank with regular petrol and drive normally.
3. Include at least one highway run of 30+ km to fully heat the catalyst.
4. Repeat for 2–3 tanks before a scheduled PUC emission test for best results.

Safety Note: For external use on vehicles only. Store away from heat and direct sunlight. Keep out of reach of children.

Frequently Asked Questions

Can Cat Complete clear a P0420 check-engine light?

Yes — if the code is triggered by carbon deposits reducing catalyst efficiency below the ECU threshold, cleaning often resolves the fault after 1–2 tanks. If the catalytic converter is physically damaged or its substrate has melted, the code will persist and replacement will be necessary.

Is this product safe for BS6 vehicles sold in India after 2020?

Absolutely. Cat Complete is formulated to be fully safe for BS6 three-way catalysts and both upstream and downstream O2 sensors. It will not harm the sensitive washcoat or lambda sensor readings that BS6 ECUs rely on.

How often should city-driven cars use Cat Complete?

Once every 20,000–25,000 km is sufficient for most vehicles. For cars used heavily in city stop-go traffic — where the catalyst rarely reaches full operating temperature — once a year before PUC renewal is a practical schedule.

Does it work with E10 and E20 petrol now sold at Indian pumps?

Yes. Cat Complete is fully compatible with E10 and E20 ethanol-blend petrol, which is now mandatory across India. It will not cause phase separation or react negatively with the ethanol content in your fuel.

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