Rislone Hy-per Diesel

Use When You Notice…

• Black smoke under acceleration: Dirty injectors spray fuel unevenly, causing incomplete combustion. This cleaner dissolves carbon deposits and restores precise spray patterns.
• PUC test borderline or failed: Fouled injectors push soot output beyond legal limits. A full system clean can bring emissions back into compliance before your next renewal.
• Rough idle or diesel rattle after warm-up: Carbon build-up on injector needles causes misfiring and increased NVH — noticeably reduced after one full tank treatment.
• Hard cold starts in winter: Low-cetane pump diesel struggles below 5°C. The cetane improver helps your engine fire cleanly from the first crank.
• Fuel economy has dropped in city driving: Stop-go traffic accelerates soot build-up. Restored injector performance means more efficient combustion and fewer trips to the pump.

Key Benefits

• Injector Deep-Clean: Dissolves hard carbon and lacquer deposits from high-pressure common-rail injector nozzles, restoring factory-spec fuel atomisation.
• Cetane Boost: Raises the cetane number of Indian pump diesel, cutting cranking time and cold-start smoke in North India winters.
• Reduced NVH: Smoother, more even combustion visibly reduces diesel knock, rattle, and cabin vibration — a top complaint among Indian CRDi owners.
• DPF Protection: Cleaner combustion produces less soot, reducing the frequency of DPF regeneration events on BS6 vehicles.
• Lubricity Restoration: Replenishes the lubricity stripped from BS6 ultra-low sulphur diesel, protecting expensive pump plungers and injector needles.
• Emissions Compliance: Helps reduce visible smoke output so your vehicle meets PUC norms and avoids NGT penalty notices in Delhi NCR and other metro zones.

The Technology Inside

Rislone Hy-per Diesel uses a concentrated package of high-detergency polyetheramine (PEA) chemistry — the same class of detergent used in professional injector bench-cleaning — to dissolve carbonaceous deposits that ordinary diesel cannot shift. A dedicated lubricity enhancer coats metal surfaces inside the high-pressure fuel pump and injector needles, compensating for the reduced sulphur content of BS6 ULSD that can accelerate wear. The cetane improver works at the molecular level to shorten the ignition delay period, giving you a crisper, more complete burn from the first combustion event. Together these chemistries address the full fuel circuit: tank, fuel filter, pump, injectors, and combustion chamber — not just one component. The result is a measurably cleaner, quieter, and more fuel-efficient diesel system after a single full tank.

Dosage & Coverage

One bottle of Rislone Hy-per Diesel treats a full diesel tank as per the label dosage — add it to a nearly empty tank before filling up so it blends thoroughly with the incoming fuel. For the deepest injector clean, include at least one sustained highway run at 80–100 km/h during the treatment tank, as higher fuel-flow rates push the detergent through the entire high-pressure circuit faster. For ongoing protection, repeat every 10,000–15,000 km or before each PUC renewal; high-mileage city taxis and commercial vehicles benefit from every 5,000 km use.

Compatibility

Safe to use with

• BS4 and BS6 common-rail diesel engines — Mahindra Scorpio, Thar, Bolero; Tata Safari, Nexon, Harrier; Maruti Ciaz SHVS; Toyota Innova Crysta, Fortuner; Ford EcoSport and Endeavour diesel variants.
• Commercial diesel vehicles including Ashok Leyland, Force Motors, Tata trucks and buses, and Mahindra load carriers.
• Compatible with DPF (Diesel Particulate Filter) — will not damage or block the particulate filter on BS6 vehicles.
• Suitable for use with biodiesel blends (B5, B7, B20) as supplied at select Indian fuel stations.
• Safe with BS6 ultra-low sulphur diesel (ULSD) mandated nationwide since April 2020.

Not suitable for

• Not a repair solution for physically worn, cracked, or seized injectors — a mechanic's bench service or replacement is needed in those cases.
• Not intended for petrol, CNG, or LPG engines.
• Will not fix a high-pressure pump that has already failed due to metal-on-metal wear.

Why It Matters in India

Indian diesel quality varies considerably between premium urban pumps and highway dhabas, and BS6 low-sulphur diesel — while cleaner burning — has lower natural lubricity than the BS4 fuel it replaced, meaning CRDi pumps and injectors face greater wear risk than ever before. Delhi NCR's odd-even rules, NGT smoke notices, and tightening PUC norms make black smoke a legal — not just mechanical — problem for Indian diesel owners. Stop-go traffic in cities like Mumbai, Bengaluru, and Kolkata keeps exhaust temperatures low, accelerating the carbon build-up that Rislone Hy-per Diesel is specifically formulated to remove. A periodic fuel system clean is no longer optional maintenance — it is essential for any CRDi diesel owner in India who wants reliable performance, compliance, and longevity.

How To Use

1. Shake the bottle and pour the full contents into your diesel tank when it is nearly empty.
2. Fill the tank completely with diesel immediately after adding the product.
3. Drive normally, including at least one sustained highway run at 80–100 km/h for best results.
4. Repeat every 10,000–15,000 km, or more frequently for high-mileage commercial use.

Safety Note: For external use in fuel tank only. Keep out of reach of children. Do not mix with engine oil or coolant. Store in a cool, dry place away from direct sunlight.

Frequently Asked Questions

Is Rislone Hy-per Diesel safe for my BS6 Mahindra or Tata diesel with a DPF?

Yes — the formula is fully DPF-safe and compatible with BS6 ultra-low sulphur diesel. It will not clog or chemically damage the diesel particulate filter; in fact, cleaner injectors produce less soot, which reduces the burden on your DPF over time.

How often should I use this product for best results?

Every 10,000–15,000 km is ideal for private cars. If you drive a taxi, auto-rickshaw, or commercial diesel vehicle clocking high city kilometres, every 5,000 km gives better protection against rapid soot build-up.

Will this help me pass my PUC emission test?

A clean fuel system produces a more complete burn with less visible smoke — which directly affects PUC smoke-opacity readings. Use a full tank of treated diesel before your next PUC appointment for the best chance of a compliant result. Note: if your injectors are mechanically damaged, a physical service will still be required.

Can I use this in older BS4 diesel vehicles like the Innova or older Scorpio?

Absolutely — the product is compatible with both BS4 and BS6 common-rail diesel engines. Older vehicles with more accumulated deposits often see the most noticeable improvement in smoothness and smoke reduction.

Is Cash on Delivery available and how fast will it arrive?

Yes, COD is available on all orders from naredi.in with free delivery across India. Most metro and Tier-1 city orders are delivered within 3–5 business days; remote PIN codes may take a few days longer.
