Rislone 44701 Hy-per Fuel Injector Cleaner Concentrate 177ml bottle — fuel system additive for petrol cars

The Best Fuel Cleaner for Indian Cars: Restore Mileage, Fix Rough Idling, and Save on Costly Injector Servicing

June 15, 2026

The petrol you fill at a station in Pune may be a completely different quality from what your neighbour filled in Delhi last week. That invisible inconsistency is silently coating your fuel injectors with gunk. It is stealing your mileage and slowly degrading your engine's performance with every kilometre you drive. If your Swift has been feeling sluggish lately, or your Creta's fuel efficiency has dropped without any obvious reason, dirty fuel injectors are very likely the culprit. A quality fuel injector cleaner could be the simplest, most cost-effective fix you have never tried.

Section 1: What Is a Fuel Cleaner and Why Does Every Indian Car Need One?

A fuel injector cleaner is a concentrated chemical additive you pour directly into your petrol tank. As it mixes with fuel and travels through your car's fuel system, it dissolves carbon deposits, varnish buildup, and other contaminants that collect on your injectors, intake valves, and combustion chamber walls over time. Think of it as a deep-clean treatment for the parts of your engine you can never see.

Why is this especially important in India? A few reasons that are unique to our conditions:

First, India's vehicle population has exploded in the last decade, and BS6-grade petrol is now mandated nationwide — a positive step. However, fuel quality at the retail level still varies significantly between states, oil marketing companies, and individual fuel stations. Trace impurities and inconsistent detergent additive levels in petrol leave microscopic deposits on injector nozzles over thousands of kilometres. These deposits narrow the spray pattern and reduce atomisation efficiency — and your mileage quietly suffers for it.

Second, Indian driving conditions are genuinely punishing. Stop-start city traffic in Bangalore or Chennai means your engine runs rich at low RPMs for extended periods. That is precisely the condition under which carbon deposits form fastest. Add extreme summer heat of 45°C+ across Rajasthan, UP, and the Deccan Plateau — plus the monsoon humidity that affects fuel vapour pressure — and your injectors are under far more stress than they were ever designed for in a European or Japanese test cycle.

According to Bureau of Energy Efficiency studies, dirty or partially clogged fuel injectors can reduce engine thermal efficiency by up to 15%. With petrol prices hovering between ₹94 and ₹106 per litre across Indian metros in 2024, that 15% inefficiency is not an abstract engineering figure. It is hundreds of rupees leaking away silently every time you fill up. A fuel injector cleaner is not a luxury — it is a genuinely practical tool for the value-conscious Indian car owner.

Pro Tip: If you have recently crossed 10,000 km on your current service interval — or your car sat unused through the monsoon months — that is the ideal time to run a fuel injector cleaner before your next scheduled service. It can save you a significant conversation, and bill, at the workshop.

Section 3: How Rislone 44701 Fuel Injector Cleaner Concentrate Works — and Why It Stands Out

The Rislone 44701 Hy-per Fuel Injector Cleaner Concentrate is a 177ml bottle of highly concentrated fuel system treatment. That word "concentrated" matters enormously when you are comparing options available in India.

Here is what makes it stand out in the Indian aftermarket:

Whole fuel system cleaning in a single treatment. Rislone 44701 is not a surface treatment. It is formulated to clean your fuel injectors, intake valves, and combustion chamber simultaneously — addressing deposit buildup at every stage of the fuel delivery and combustion process. You are not partially solving the problem. You are treating the entire pathway that petrol travels from your tank to your engine.

BS6 compatible. BS6-grade petrol has been mandatory across India since April 2020, so it is important that any additive you use is compatible with low-sulphur fuel formulations. Rislone 44701 is engineered for modern petrol engines running on BS6 fuel. It is safe and effective for virtually every current petrol car sold in India — from the Hyundai Creta 1.5L to the Kia Sonet to the Tata Nexon turbo-petrol.

Exceptional concentration value. This is where the economics become very interesting for the value-conscious Indian buyer. A single 177ml bottle treats one full tank of fuel — that is all it takes. Compare this to larger, more diluted additive bottles sold in Indian auto parts shops or on e-commerce platforms, where you may need 300–500ml to achieve the same treatment strength. Per-treatment, Rislone 44701 is significantly more cost-effective. And given that authorised service centres charge ₹2,000–₹6,000 for a professional injector cleaning service, the savings over a year of DIY maintenance are very real.

Trusted international formulation. Rislone is an American automotive chemical brand with decades of OEM-level formulation experience. The 44701 concentrate uses advanced polyether amine-based detergent technology that aggressively — but safely — dissolves carbon deposits, varnish, and lacquer from metal injector surfaces. It restores the precise spray pattern your engine was designed to deliver from day one.

For Indian car owners who want to do more than hope their next service interval fixes the problem, Rislone 44701 is one of the most practical between-service tools you can keep in your boot. If you are also interested in other fluid system maintenance products, the Rislone 44629 Power Steering Stop Leak & Seal Conditioner is another excellent Rislone product available on Naredi for addressing power steering fluid leaks and seal conditioning.

And while you are thinking about your car's overall health, battery-related issues are another major cause of hard starts in Indian conditions. The CTEK CT5 PowerSport 12V Battery Charger is a fantastic companion product to keep your battery in peak condition alongside your fuel system. Pair it with the CTEK Comfort Connect Eyelet M8 for quick, hassle-free connections every time.

Pro Tip: If your check engine light has come on alongside rough idling or hesitation, use the BlueDriver Pro OBD2 Scanner to read fault codes before heading to the workshop. Injector-related codes — such as P0300 misfire codes — are common culprits that a fuel injector cleaner treatment can often resolve on its own, saving you an unnecessary diagnostic fee.

Section 4: How to Use a Fuel Injector Cleaner in Your Car: Simple Step-by-Step Guide

One of the biggest advantages of a concentrated fuel injector cleaner like Rislone 44701 is that you genuinely do not need a mechanic, a workshop, or any special tools. Here is exactly how to use it — whether you drive a Maruti Suzuki hatchback or a Mahindra Thar:

Start with a low fuel level. Before your next fill-up, let your fuel gauge drop to approximately one quarter of a tank — or close to the low fuel indicator. This ensures the concentrate mixes with a full tank of fresh petrol for maximum effectiveness.
Pour the concentrate in first. Uncap your fuel filler and open the Rislone 44701 bottle. Pour the entire 177ml contents into your fuel tank before you add petrol. This allows the petrol to mix with the concentrate as it enters, distributing it evenly throughout the fuel.
Fill up with a full tank of BS6 petrol. Top up as you normally would. Any major fuel station — HPCL, BPCL, Indian Oil, or Reliance — is perfectly fine. The concentrate will mix automatically with the petrol.
Drive normally. There is nothing else you need to do. Simply drive your car as you normally would over the next full tank. The detergent chemistry in Rislone 44701 works continuously as the treated fuel flows through your injectors, intake valves, and combustion chambers — dissolving and burning off accumulated deposits as you drive.
Repeat every 5,000–10,000 km for ongoing maintenance. For best results, use a fuel injector cleaner every 5,000–10,000 km — roughly every one to two service intervals. This prevents deposit buildup from occurring in the first place, rather than waiting until symptoms become noticeable and costly.

Pro Tip: If you are using a fuel injector cleaner for the first time on a car that has covered more than 30,000 km without one, you may notice slightly rougher running during the first 50–100 km. This happens as loosened deposits are flushed through the system. It is completely normal, temporary, and a sign the product is working exactly as it should.

Maintaining your fuel system does not have to mean expensive workshop visits or waiting for a scheduled service that is still two months away. For Indian car owners managing rising petrol prices and demanding daily driving conditions, a concentrated fuel injector cleaner is one of the smartest, most cost-effective tools you can add to your regular maintenance routine.
