Rislone Hyper Diesel Complete Fuel System Cleaner + Diesel Conditioner And Treatment 500ml

Use When You Notice…

• Black smoke under hard acceleration: Clogged injectors mis-spray fuel, causing unburnt soot — this cleaner dissolves those carbon deposits at the source.
• Borderline or failed PUC smoke test: A dirty fuel system pushes emissions above permissible limits; one treatment cycle can bring readings back within NGT norms.
• Rough cold start with excessive cranking smoke in winter: Low cetane diesel and dirty injectors make morning starts harder — especially in Delhi, Chandigarh or Amritsar below 3°C.
• Noticeable drop in fuel economy on city runs: Stop-go traffic builds soot fastest; clean injectors restore precise spray and recover lost kilometres per litre.
• Diesel rattle, knock or increased NVH: Uneven injector delivery causes combustion timing variation — cleaning restores smooth, quiet operation.

Key Benefits

• Injector Deep-Clean: High-detergency chemistry dissolves carbon fouling inside CRDi injector nozzles, restoring factory-spec spray pattern and power.
• Cetane Improver: Boosts the effective cetane rating of Indian pump diesel for quicker ignition, smoother power delivery and reduced cold-start smoke.
• Black Smoke Reduction: Cleaner combustion means visibly less soot — real help ahead of PUC renewals and odd-even compliance checks.
• Lubricity Protection: Replaces the natural lubricity stripped out of BS6 ultra-low sulphur diesel, guarding high-pressure pump plungers from scuffing wear.
• Corrosion Inhibition: Active corrosion inhibitors protect steel fuel lines and tank against rust — critical during India's monsoon season.
• NVH Improvement: More even combustion across all cylinders reduces diesel rattle and harshness felt through the cabin floor and steering wheel.

The Technology Inside

Rislone Hy-per Diesel uses a concentrated package of polyetheramine (PEA) detergents — the same class of chemistry used in OEM-approved fuel system service — that penetrate baked-on carbon deposits inside common-rail injector nozzles without softening or damaging injector seals. A dedicated lubricity additive compensates for the reduced sulphur content of BS6 ULSD, forming a protective boundary film on high-pressure pump plungers and injector needles where metal-to-metal contact is most severe. Combustion catalyst components raise the effective cetane index of Indian pump diesel, shortening ignition delay and producing a more complete burn that leaves less raw soot to load the DPF. The formula is fully miscible with bio-diesel blends such as B5 and B7 commonly dispensed at Indian retail fuel stations. No solvents aggressive enough to degrade rubber fuel hoses or O-rings are present — the liquid is safe for continuous use as a maintenance additive.

Dosage & Coverage

One 500 ml bottle treats a standard passenger car diesel tank (40–70 litres) or one fill of a light commercial vehicle. Add the full bottle to a nearly empty tank before filling with diesel so the cleaner mixes thoroughly with fresh fuel. For a deeply fouled system or a high-mileage commercial vehicle, repeat treatment every 5,000 km; for routine maintenance, every 10,000–15,000 km is sufficient.

Compatibility

Safe to use with

• BS4 and BS6 common-rail and CRDi diesel engines — Mahindra Scorpio, XUV, Bolero; Tata Safari, Nexon, Ace; Ashok Leyland and Force Motors commercial vehicles.
• Turbocharged diesel engines including those fitted with variable-geometry turbines.
• Diesel Particulate Filters (DPF) — formula is fully DPF-safe.
• Bio-diesel blends up to B20 as used at select Indian fuel stations.
• Ultra-low sulphur diesel (ULSD) mandated under BS6 regulations.

Not suitable for

• Petrol, CNG or LPG engines — use the appropriate Rislone fuel-type product.
• Physically worn or mechanically damaged injectors and high-pressure pumps — a chemical cleaner cannot restore metal worn beyond tolerance.
• Engines with active fuel-system leaks or cracked fuel rails.

Why It Matters in India

Indian diesel quality varies considerably between premium city pumps and highway dhabas, and BS6 low-sulphur diesel — while cleaner for emissions — has reduced the natural lubricity that BS4 diesel provided to precision fuel-injection components. Stop-go traffic in cities like Mumbai, Bengaluru and Delhi keeps coolant temperatures low, which is exactly the condition where soot deposits form fastest inside injectors. Seasonal extremes compound the problem: North India winters demand reliable cold starts, while summer heat in Rajasthan and the Deccan plateau stresses fuel pump materials. A periodic diesel engine additive clean is no longer optional maintenance for CRDi diesel owners — it is essential.

How To Use

1. Shake the bottle well, then open and pour the full 500 ml into your nearly empty diesel tank.
2. Fill the tank with fresh diesel immediately after adding the treatment.
3. Drive normally; include at least one sustained highway run above 80 km/h for maximum injector cleaning.
4. Repeat every 10,000–15,000 km, or every 5,000 km for taxis and commercial vehicles.

Safety note: For external use on vehicles only. Keep away from children. In case of skin or eye contact, rinse thoroughly with water. Do not mix with engine oil.

Frequently Asked Questions

Is this safe for my BS6 Mahindra XUV700 or Tata Nexon diesel with a DPF?

Yes — the formula is fully DPF-safe and contains no compounds that can melt, block or damage diesel particulate filters. It is also compatible with the AdBlue/DEF SCR systems fitted on some BS6 commercial diesel engines.

How often should I use this for best results?

Every 10,000–15,000 km for private cars, or before each PUC renewal. City taxis, auto-rickshaws and commercial vehicles running high annual mileage benefit most from treatment every 5,000 km due to heavier soot loading in stop-go conditions.

Will it help my vehicle pass the PUC smoke emission test?

Cleaner injectors produce a more complete burn with measurably less particulate smoke. Many users report a visible reduction in black exhaust smoke after one full tank cycle, which directly improves smoke opacity readings at PUC centres. It is not a guaranteed pass, but it addresses the root cause of high smoke readings.

Will this help with DPF regeneration intervals?

Yes — cleaner combustion generates less raw soot per cycle, so the DPF fills more slowly and active regeneration events become less frequent. This reduces the fuel penalty associated with forced DPF regen on BS6 vehicles.

Is Cash on Delivery available and how long does delivery take?

Yes, COD is available across India through naredi.in. Standard delivery takes 3–6 business days depending on your pin code, with free shipping on all orders.
