Rislone Hy-per Diesel

Use When You Notice…

• Black smoke under acceleration: Dirty injectors cause incomplete combustion; this cleaner restores the fine spray pattern that burns diesel completely and reduces visible smoke.
• Diesel rattle or worsening NVH: Carbon deposits on injector needles cause uneven fuelling — cleaning them noticeably reduces Noise, Vibration and Harshness in CRDi engines.
• PUC test borderline or failed: A cleaner fuel system lowers particulate output, giving you a better chance of passing the smoke opacity check the first time.
• Fuel economy has dropped in city driving: Stop-go traffic accelerates soot build-up; one treatment can recover the mileage you have quietly been losing.
• Rough or smoky cold starts in winter: Fouled injectors struggle most when fuel is cold and viscous — cleaning them restores a clean, consistent spray even on the coldest January mornings.

Key Benefits

• Full System Clean: Cleans injectors, high-pressure pump, fuel lines and combustion chambers in a single fill — no dismantling required.
• Cetane Improver: Boosts the effective cetane rating of Indian pump diesel, reducing diesel knock and improving throttle response on both city roads and highways.
• Emission Reduction: Cleaner combustion means lower soot output — directly supporting your PUC certificate renewal and NGT compliance in Delhi NCR.
• DPF Protection: Produces less soot per cycle, reducing the frequency of DPF regeneration events and extending filter life on BS6 vehicles.
• Lubricity Enhancement: Restores the lubricity that low-sulphur BS6 diesel lacks, protecting precision pump plungers and injector needles from premature wear.

The Technology Inside

Rislone Hy-per Diesel uses a high-detergency polyetheramine (PEA) concentrate — the same injector-cleaning chemistry used in premium branded fuel additives globally — formulated specifically for the fuel chemistry of Indian BS6 ultra-low sulphur diesel. It dissolves and suspends lacquer, varnish and hard carbon deposits from injector nozzle tips and needle seats, restoring the precise micro-spray pattern that CRDi systems depend on for efficient combustion. Lubricity agents coat metal surfaces inside the high-pressure pump, compensating for the reduced sulphur content that made BS4 diesel naturally more lubricating. The result is quieter combustion, lower exhaust opacity and measurably better thermal efficiency — all without altering the fuel's chemical composition in a way that could harm modern oxygen sensors or DPF substrates.

Dosage & Coverage

One bottle of Rislone Hy-per Diesel treats a full diesel tank as specified on the product label — simply add it before filling up. For best results, include at least one sustained highway run at 80–100 km/h during the treatment tank to maximise injector cleaning through high fuel-flow conditions. For high-mileage city taxis and commercial vehicles, repeat every 5,000 km; for private cars use every 10,000–15,000 km or before each PUC renewal.

Compatibility

Safe to use with

• BS4 and BS6 common-rail diesel engines — Mahindra Scorpio, Thar, XUV; Tata Safari, Nexon, Harrier; Toyota Innova, Fortuner; Maruti S-Cross and Ciaz 1.5 diesel variants
• Commercial diesel vehicles from Ashok Leyland, Force Motors and Tata Motors — trucks, buses and light commercial vehicles
• Ultra-low sulphur diesel (ULSD) mandated under BS6 norms across India
• Bio-diesel blends (up to B7) commonly used at Indian fuel stations
• Vehicles fitted with diesel particulate filters (DPF) — fully DPF-safe formula

Not suitable for

• Physically damaged or mechanically worn injectors and high-pressure pumps — chemical cleaning cannot restore worn metal components
• Petrol, CNG or LPG engines — diesel fuel systems only

Why It Matters in India

Indian diesel quality varies significantly between premium city pumps and rural highway stations — even within BS6 mandates, batch quality is inconsistent. Stop-go traffic in cities like Mumbai, Bengaluru and Delhi keeps diesel engines at low operating temperatures where soot deposits form fastest, and the NGT's strict emission enforcement means a sooty exhaust is now a legal liability, not just a mechanical one. BS6 low-sulphur diesel, while cleaner burning, strips away the natural lubricity that protected older common-rail systems — making a periodic full-system clean with a lubricity-restoring additive essential maintenance, not optional, for Indian CRDi diesel owners.

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 treatment.
3. Drive normally, including at least one sustained highway run for maximum cleaning effect.
4. Repeat every 10,000–15,000 km or as your driving conditions require.

Safety note: Keep away from children. Store in a cool, dry place away from direct sunlight. Do not mix with engine oil or coolant — for diesel fuel system use only.

Frequently Asked Questions

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

Yes — Rislone Hy-per Diesel is fully DPF-safe and will not damage or block your diesel particulate filter. In fact, cleaner injectors produce less soot per combustion cycle, which reduces how often your DPF needs to regenerate and extends its service life.

How often should I use this for best results?

For private diesel cars, use every 10,000–15,000 km or before each PUC certificate renewal. High-mileage city taxis, auto-rickshaws and commercial diesel vehicles operating in heavy stop-go traffic will benefit from treatment every 5,000 km.

Will this help me pass my PUC emission test?

A cleaner fuel system burns diesel more completely, which directly reduces exhaust smoke opacity — the primary measurement in India's PUC smoke test. Use one tank treatment before your next PUC check for the best chance of passing first time, especially if your vehicle has been running in city conditions.

My Mahindra/Tata diesel rattles in the morning — will this fix it?

Diesel rattle on cold start is often caused by carbon deposits on injector needles causing uneven fuel delivery. Rislone Hy-per Diesel dissolves these deposits and restores a consistent spray pattern, which typically reduces the characteristic CRDi rattle and NVH noticeably within one treatment tank.

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

Yes — Cash on Delivery is available across India, and delivery is free nationwide. Most orders are delivered within 3–5 business days depending on your location, with tracking details sent to your registered mobile number.
