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 with cranking smoke in winter: Low-cetane pump diesel struggles below 5°C. The cetane improver in this product helps your engine fire cleanly from the first crank.
• Fuel economy has dropped in city driving: Stop-go traffic accelerates soot build-up on injectors. Restoring clean spray patterns directly recovers lost kilometres per litre.

Key Benefits

• Injector Deep-Clean: Dissolves varnish, carbon, and lacquer deposits from high-pressure common-rail injectors for a restored, precise fuel spray pattern.
• Cetane Boost: Raises the cetane rating of Indian pump diesel, delivering smoother ignition and eliminating that characteristic diesel knock on cold mornings.
• Black Smoke Reduction: Cleaner combustion means visibly less black exhaust smoke under load — a critical advantage when PUC renewal is due.
• DPF Protection: The liquid formula is fully DPF-safe, reducing soot loading and the frequency of forced DPF regeneration events on BS6 vehicles.
• Lubricity Restoration: Compensates for the reduced lubricity of BS6 ultra-low sulphur diesel, protecting pump plungers and injector needles from premature wear.
• Fuel Economy Recovery: Users typically report a measurable improvement in fuel economy after one full tank cycle, especially on high-mileage city vehicles.

The Technology Inside

Rislone Hy-per Diesel combines a concentrated polyetheramine (PEA) detergent package with cetane improver chemistry and a lubricity additive into a single liquid treatment. The PEA detergents target carbon and varnish deposits that accumulate specifically on common-rail injector needles and pintle seats — the root cause of uneven fuel atomisation and black smoke. The cetane improver works by shortening ignition delay, which means the air-fuel mixture ignites more completely and at the right moment in the combustion cycle, reducing both knock and unburnt fuel in the exhaust stream. The lubricity enhancer forms a micro-thin protective layer on high-pressure pump plungers and injector components, counteracting the scuffing risk that BS6 ultra-low sulphur diesel introduces. Unlike solvent-heavy competitors, this formula does not alter fuel rail pressure or harm rubber seals.

Dosage & Coverage

One bottle of Rislone Hy-per Diesel treats a full diesel tank as specified on the product label — add the entire contents to a nearly empty tank before filling with diesel. For maximum injector cleaning, include at least one sustained highway run at consistent speed during the treatment cycle. For high-mileage commercial vehicles or taxis, use every 5,000 km; for private passenger cars, every 10,000–15,000 km or before each PUC renewal.

Compatibility

Safe to use with

• BS4 and BS6 common-rail diesel engines — Mahindra, Tata, Maruti, Toyota, Ford, Ashok Leyland, and Force Motors diesel vehicles.
• DPF-equipped BS6 vehicles — will not damage diesel particulate filters.
• ULSD (ultra-low sulphur diesel) mandated under BS6 and biodiesel blends used across India.
• Commercial vehicles including trucks, buses, and tractors running on Indian pump diesel.

Not suitable for

• Physically damaged, cracked, or mechanically worn injectors — this is a chemical cleaner, not a mechanical repair.
• High-pressure fuel pumps with worn plungers beyond serviceable tolerance.
• Petrol, LPG, or CNG engines.

Why It Matters in India

Indian diesel quality varies significantly between premium city pumps and highway dhabas, and BS6 low-sulphur diesel removes the natural lubricity that older BS4 fuel provided — meaning CRDi injection systems are under more stress than ever. Delhi NCR's odd-even rules and NGT pollution notices make black smoke not just an inconvenience but a legal and financial risk. North India winters regularly push temperatures below 3°C in December and January, where low-cetane pump diesel causes hard starts and white cranking smoke that can foul injectors further. A periodic treatment with Rislone Hy-per Diesel is practical, cost-effective preventive maintenance for every Indian CRDi diesel owner.

How To Use

1. Shake the bottle and pour the entire contents into your diesel tank when it is nearly empty.
2. Fill the tank completely with diesel from your regular pump immediately after adding the treatment.
3. Drive normally, and include at least one highway run at sustained speed for best injector cleaning results.
4. Repeat every 10,000–15,000 km, or every 5,000 km for taxis and commercial vehicles.

Safety Note: Keep away from children. Do not mix with petrol or engine oil. Store in a cool, dry place away from direct sunlight. For external use on fuel systems only.

Frequently Asked Questions

Is this product safe for my BS6 Mahindra Scorpio-N or Tata Safari's DPF?

Yes — Rislone Hy-per Diesel is fully DPF-safe and compatible with all BS6 common-rail diesel engines including Mahindra, Tata, and Toyota. It will not clog or damage your diesel particulate filter; in fact, cleaner injectors produce less soot, which reduces the frequency of DPF regeneration cycles.

Will it help me pass my PUC emission test?

A clean injector delivers a more complete, controlled burn that produces significantly less black smoke and particulate matter in the exhaust. Many vehicle owners use Rislone Hy-per Diesel one full tank before their PUC renewal date to bring emission readings back within legal limits. It is not a guaranteed fix if underlying mechanical faults exist.

How often should I use this product?

For private diesel cars, every 10,000–15,000 km or before each PUC renewal is sufficient. High-mileage city taxis, auto-rickshaws, and commercial diesel vehicles benefit from more frequent use every 5,000 km due to the constant stop-go load on injectors.

My diesel engine is very noisy and rattles on cold mornings — will this fix it?

Diesel rattle and NVH (Noise, Vibration, Harshness) on cold starts are often caused by low cetane fuel and partially clogged injectors delivering uneven fuel pulses. The cetane improver and detergent package in this product directly address both root causes, and most users notice a quieter, smoother idle within one full tank cycle.
