Rislone Hy-per Diesel

Use When You Notice…

• Black smoke under acceleration: Incomplete combustion from dirty injectors causes visible soot — this cleaner restores precise spray patterns to burn diesel cleanly.
• Borderline or failed PUC emission test: High particulate readings often trace back to fouled injectors; a full-system clean can bring emissions back within limits.
• Diesel rattle or increased NVH (Noise, Vibration, Harshness): Carbon deposits disrupt injector timing, causing that characteristic diesel knock to worsen — cleaning restores smooth combustion.
• Rough or hard cold starts in winter: Soot-laden injectors deliver uneven fuel spray at low temperatures; cleaner injectors ignite more reliably at 3–5°C winter mornings in Delhi or Chandigarh.
• Noticeable drop in kilometres per litre: Partially blocked injectors waste fuel — restoring spray efficiency directly recovers mileage lost to deposit buildup.

Key Benefits

• Injector Deep-Clean: Dissolves carbon and varnish deposits inside CRDi injector nozzles, restoring factory-spec spray patterns and lost power.
• Black Smoke Reduction: Cleaner combustion cuts visible soot output, helping diesel vehicles meet NGT norms and pass PUC checks across Indian cities.
• Cetane Booster Effect: Improves the ignition quality of Indian pump diesel, reducing diesel knock and delivering a smoother, quieter power stroke.
• Lubricity Protection: Replenishes the lubricity stripped from BS6 low-sulphur diesel, shielding precision pump plungers and injector needles from premature wear.
• Corrosion Inhibitor: Guards fuel lines, tank and injector bodies against rust — especially valuable during India's monsoon season when moisture ingress is highest.
• DPF Regeneration Support: Cleaner combustion produces less soot loading on the diesel particulate filter, reducing forced regeneration events and protecting DPF longevity.

The Technology Inside

Rislone Hy-per Diesel uses a concentrated high-detergency polyetheramine (PEA) chemistry specifically formulated for common-rail direct injection diesel systems, where fuel pressures can exceed 2,000 bar and injector tolerances are measured in microns. Unlike generic fuel additives blended for petrol engines, the diesel-specific surfactant package here targets the hard, baked-on carbonaceous deposits that form on injector tips during the low-speed, high-load city driving typical of Indian conditions. A dedicated lubricity-enhancement package compensates for the reduced sulphur content in BS6 ULSD (ultra-low sulphur diesel), which naturally provides less boundary lubrication than older BS4 grades. The formula also includes combustion-chamber detergents that clean crown and valve deposits simultaneously, contributing to the reduction in diesel rattle and NVH that many Indian owners report after the first treatment. Every batch is manufactured in the USA to Rislone's original chemistry — not a repurposed or diluted private-label product.

Dosage & Coverage

One 500 ml bottle treats a standard diesel passenger car tank (40–70 litres) for one complete cleaning cycle. Add the full bottle to a nearly empty tank before filling with diesel so the additive mixes thoroughly across the entire fuel charge. For heavily fouled systems — high-mileage taxis, fleet vehicles or engines showing persistent black smoke — repeat treatment at the next two fill-ups, then move to a maintenance dose every 10,000–15,000 km.

Compatibility

Safe to use with

• BS4 and BS6 common-rail diesel engines — Mahindra Scorpio-N, Thar, XUV700; Tata Safari, Harrier, Nexon; Ashok Leyland and Force Motors commercial vehicles
• Turbocharged CRDi engines in Maruti Ciaz, Toyota Innova Crysta and Ford Endeavour (older stock)
• DPF-equipped BS6 vehicles — formula will not block or damage diesel particulate filters
• Biodiesel blends (B5–B20) commonly supplied at select Indian fuel stations
• ULSD (ultra-low sulphur diesel) mandated under BS6 regulations across India

Not suitable for

• Physically cracked, seized or mechanically worn injectors — a chemical cleaner cannot restore damaged hardware
• High-pressure fuel pumps already showing metal debris or catastrophic wear
• Petrol, CNG or LPG fuel systems

Why It Matters in India

Indian pump diesel quality varies considerably — premium outlets in metros dispense cleaner fuel, while highway dhabas and smaller towns can supply diesel with higher contamination levels that accelerate injector fouling. BS6 low-sulphur diesel, while cleaner for the air, has reduced the natural lubricity that BS4 diesel provided, meaning CRDi pumps and injectors wear faster without a lubricity additive. Stop-go traffic in cities like Mumbai, Bengaluru and Delhi keeps coolant temperatures low, allowing soot and unburnt fuel to condense on injector tips far quicker than highway driving does. A periodic full-system clean is practical, cost-effective maintenance for any Indian diesel owner who wants to stay ahead of PUC notices, avoid expensive injector replacements and keep their engine running as the manufacturer intended.

How To Use

1. Shake the bottle well and add the entire contents to your diesel fuel tank when it is nearly empty.
2. Fill the tank fully with diesel immediately after adding the cleaner so it blends completely.
3. Drive normally, but include at least one sustained highway run at moderate speed for maximum injector cleaning action.
4. Repeat every 10,000–15,000 km as routine maintenance, or before each PUC renewal.

Safety Note: For external use in the fuel tank only. Keep away from open flames. Store below 45°C — do not leave in a parked vehicle during peak Indian summer.

Frequently Asked Questions

Is this safe for my BS6 diesel car's DPF filter?

Yes — Rislone Hy-per Diesel is fully DPF-safe and contains no substances that can melt, block or chemically damage diesel particulate filters. In fact, by producing a cleaner, more complete combustion, it reduces the soot load entering the DPF and may extend the interval between regeneration events.

How often should I use this for best results?

For passenger cars, once every 10,000–15,000 km or before each PUC certificate renewal is the recommended maintenance interval. High-mileage city taxis, school buses and commercial vehicles operating on inconsistent fuel should treat every 5,000 km for consistent injector cleanliness.

Will it help reduce black smoke and help pass my PUC test?

Cleaning fouled injectors restores complete, even combustion — which directly reduces particulate and visible smoke emissions. Many users report noticeable improvement in smoke levels after one full-tank treatment, though severely neglected systems may benefit from two consecutive treatments before a PUC check.

Is it compatible with my Mahindra or Tata diesel vehicle?

Yes — this cleaner is compatible with all common-rail CRDi diesel engines, including the full range of Mahindra, Tata, Ashok Leyland and Force Motors diesel vehicles sold in India on both BS4 and BS6 fuel standards. If in doubt, check your vehicle owner's manual for fuel additive guidance.

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

Yes — naredi.in offers Cash on Delivery across India with free delivery on all orders. Most metro orders are delivered within 3–5 business days; tier-2 and tier-3 cities may take up to 7 business days depending on your pin code.
