Rislone Hy-per Diesel

Clean Injectors, Fuel Pump & Fuel System in One Treatment

Complete fuel system cleaner engineered to help clean and maintain petrol and diesel fuel systems, including common-rail diesel engines. Ideal for vehicles operating in India's variable fuel quality, stop-go city traffic, and demanding driving conditions.

• Helps clean fuel injectors, fuel-system components, and combustion-related deposits in a single tank treatment.

• Helps reduce rough idle, hesitation, engine knocking, and visible exhaust smoke caused by fuel-system deposits.

• For diesel engines, the cetane-improving chemistry helps support smoother ignition and cold starts.

• DPF-safe formula for compatible diesel vehicles equipped with diesel particulate filters.

• Helps restore engine performance and fuel economy affected by injector and fuel-system deposits.

Use When You Notice…

• Black smoke under acceleration: Dirty or contaminated diesel injectors can deliver fuel unevenly, resulting in incomplete combustion. A quality fuel-system cleaner helps remove deposits and supports a cleaner spray pattern.

• Rough idle or engine vibration: Deposits around injector components can affect fuel delivery. Cleaning the fuel system can help restore smoother engine operation.

• Hard cold starts: Fuel-system deposits can affect fuel atomisation and combustion. In diesel engines, the cetane-improving properties can help support smoother ignition during cold starts.

• Fuel economy has dropped: Deposit build-up and inefficient fuel delivery can reduce combustion efficiency. Cleaning the fuel system can help recover lost performance and economy.

• Engine hesitation or sluggish acceleration: Deposits in the fuel system can interfere with proper fuel delivery. Regular cleaning helps maintain efficient fuel flow and injector performance.

Key Benefits

• Injector Deep-Clean: Helps dissolve and remove varnish, carbon, and other fuel-system deposits that can affect injector performance and fuel atomisation.

• Fuel System Cleaning: Helps clean injectors and other fuel-system components to support consistent fuel delivery.

• Diesel Cetane Support: For diesel engines, the cetane-improving chemistry helps promote smoother ignition and combustion.

• Smoke Reduction: Cleaner fuel delivery and more efficient combustion can help reduce visible exhaust smoke caused by fuel-system deposits.

• DPF Protection: Suitable for compatible DPF-equipped diesel vehicles and helps support cleaner combustion, which can help reduce excessive soot production.

• Lubricity Support: Helps provide fuel-system lubricity to support the protection and smooth operation of fuel-system components.

• Fuel Economy Recovery: Cleaning deposits from the fuel system can help restore performance and fuel economy when deposits are contributing to poor combustion or fuel delivery.

The Technology Inside

Rislone Hy-per Fuel combines advanced detergent chemistry with fuel-system cleaning and performance-supporting additives designed to help remove deposits from fuel injectors and other fuel-system components.

The cleaning agents target deposits that can affect injector performance, fuel atomisation, and combustion efficiency. In diesel applications, the cetane-improving chemistry helps reduce ignition delay and supports smoother combustion, particularly during cold starts.

The formula also provides fuel-system lubricity support, helping maintain the smooth operation of fuel-system components.

Regular use helps maintain cleaner injectors and consistent fuel delivery without requiring a workshop visit for routine fuel-system cleaning.

Dosage & Coverage

Use the product according to the dosage and application instructions printed on the product label.

For best results, add the recommended quantity to the fuel tank before refuelling and allow the treatment to work through the normal driving cycle.

For maximum cleaning performance, a sustained highway drive can help circulate the treated fuel through the fuel system.

For regular preventive maintenance, follow the recommended treatment interval on the product label.

Compatibility

Safe to Use With

• Petrol and diesel engines compatible with the product's label specifications.

• Common-rail diesel fuel systems.

• BS4 and BS6 compatible diesel vehicles.

• Compatible DPF-equipped diesel vehicles.

• Vehicles using regular pump fuel and compatible fuel blends.

• Passenger cars, SUVs, commercial vehicles, trucks, buses, and other compatible petrol or diesel vehicles.

Important

This is a fuel-system cleaning and maintenance treatment, not a mechanical repair. It cannot repair physically damaged, cracked, severely worn, or mechanically defective injectors, fuel pumps, fuel lines, or other fuel-system components.

Always check the product label for the recommended application and dosage for your specific vehicle.

Why It Matters in India

Indian vehicles regularly operate in demanding conditions including heavy traffic, frequent stop-start driving, long idling periods, varying fuel quality, dust, and extreme seasonal temperatures.

These conditions can contribute to fuel-system deposits over time. Deposits around injectors and other fuel-system components can affect fuel delivery, combustion quality, engine smoothness, and fuel economy.

For diesel vehicles, modern common-rail injection systems operate at very high pressures and require precise fuel delivery. Keeping the fuel system clean can help maintain smooth engine operation and performance.

For petrol vehicles, clean injectors and an efficient fuel system help support proper fuel atomisation and consistent combustion.

A periodic fuel-system treatment is therefore a practical preventive-maintenance step for both petrol and diesel vehicle owners.

How To Use

1. Shake the bottle well before use.

2. Add the recommended amount of Rislone Hy-per Fuel to the fuel tank according to the product label.

3. Refuel with petrol or diesel as appropriate for your vehicle.

4. Drive normally and allow the treated fuel to circulate through the complete fuel system.

5. For best cleaning results, include a sustained highway drive during the treatment cycle.

6. Repeat treatment according to the recommended interval stated on the product label.

Safety Note: Keep away from children. Do not mix with engine oil or use in applications not specified on the product label. Store in a cool, dry place away from direct sunlight. Use only as directed for fuel-system applications.

Frequently Asked Questions

Is this product suitable for both petrol and diesel vehicles?

Yes. Rislone Hy-per Fuel is designed as a fuel-system treatment for compatible petrol and diesel applications. Always follow the dosage and application instructions provided on the product label.

Is this product safe for BS6 diesel vehicles with a DPF?

Yes, for compatible applications, the formula is designed to be DPF-safe. Keeping injectors and the fuel system clean can also support more efficient combustion and help control excessive soot production.

Will it help reduce black smoke?

It can help reduce visible smoke when the smoke is related to fuel-system deposits or poor fuel atomisation. However, excessive smoke caused by mechanical problems, turbocharger issues, EGR faults, injector damage, or other engine faults requires proper diagnosis and repair.

Will it improve fuel economy?

A fuel-system cleaner can help restore fuel-system performance when deposits are contributing to inefficient fuel delivery or combustion. Actual fuel-economy improvement depends on the vehicle's condition, driving style, fuel quality, and the cause of the efficiency loss.

Will it help with diesel cold starts?

For diesel applications, the cetane-improving chemistry can support smoother ignition and combustion, particularly during cold starts. However, a hard-starting vehicle may have an underlying battery, glow-plug, injector, fuel, or engine issue that requires diagnosis.

Can I use it before a PUC test?

A clean fuel system can support better combustion and lower emissions when deposits are contributing to the problem. However, no fuel additive can guarantee a PUC pass if the vehicle has an underlying mechanical or emissions-system fault.

How often should I use this product?

Use it according to the treatment interval and dosage specified on the product label. For vehicles used frequently in heavy traffic or demanding conditions, regular preventive fuel-system cleaning can help maintain injector and fuel-system performance.
