Catalytic converter cleaner additive for petrol engines, 120ml bottle, fuel treatment with ferrocene, polyether amine, dodecane, and phosphate ester ingredients to clean injectors and restore performance.
Catalytic Converter Cleaner: 120ml Petrol Fuel System Treatment with Ferrocene

This catalytic converter cleaner is a 120ml fuel additive designed for use in petrol engines. Its formula combines six specific ingredients—polyether amine, dodecane, fatty acid ester, mineral oil, phosphate ester, and ferrocene—to tackle carbon and soot deposits throughout the fuel and exhaust systems. By cleaning fuel injectors, intake valves, and combustion chambers, it aims to restore engine responsiveness and efficiency that can be lost over time due to fouling. The treatment is concentrated into a single 120ml bottle, sufficient for one full tank of fuel when used according to standard additive procedures.
Features and Construction
The product is defined by its specific chemical composition and its application as a liquid fuel treatment. The 120ml volume is a standard single-treatment size for this type of maintenance product.
Material and Build
The cleaner is a liquid blend of the stated ingredients. Polyether amine acts as a detergent to dissolve varnish and gum deposits in the fuel system. Dodecane serves as a hydrocarbon solvent. Fatty acid esters and mineral oil provide the liquid carrier base. Phosphate ester can contribute detergent or anti-wear properties. The inclusion of ferrocene is notable, as this organometallic compound is known to catalyse soot oxidation, helping to reduce particulate matter and carbon buildup in the exhaust system and on the catalytic converter substrate itself.
Size and Practical Fit
The product is supplied in a single 120ml bottle. This is a practical, one-use size that is easily poured into a standard petrol tank filler neck. It is designed to be mixed with a full tank of fuel, ensuring the treatment is diluted and distributed throughout the entire fuel system during normal driving.
Uses and Placement
This cleaner is intended for preventative maintenance and performance restoration in petrol-powered vehicles. It addresses issues related to fuel system fouling and exhaust system restrictions.
Event or Professional Use
For vehicles used in demanding conditions, such as frequent short trips, stop-start city driving, or towing, which can promote faster carbon buildup, this treatment can be part of a scheduled maintenance routine. Mechanics or enthusiasts might use it to help rectify symptoms of a partially clogged catalytic converter or dirty injectors before more invasive repairs are considered.
Everyday Home Use
For the average driver, this additive offers a straightforward method for maintaining fuel system cleanliness. It can be used periodically—for instance, every few thousand miles or before a long journey—to help maintain engine performance, fuel economy, and emissions compliance. It is a consumer-level product for DIY application.
Benefits and Buying Value
The value lies in its potential to improve engine operation through cleaning, using a formula that includes specific active ingredients like ferrocene.
Reuse and Low Maintenance
The 120ml bottle is a single-use treatment. The 'reuse' benefit comes from the intended outcome: a cleaner engine and exhaust system that may operate more efficiently for longer between treatments. By helping to keep the catalytic converter free of excess carbon, it may support the longevity of this expensive component. Regular use as a maintenance item can be seen as a low-cost form of preventative care.
Why Choose This Product
This cleaner is distinguished by its explicitly stated six-ingredient formula, which includes ferrocene—a compound with recognised effects on soot oxidation. For buyers comparing fuel additives, this provides a concrete, technical point of differentiation from generic 'fuel system cleaners'. The 120ml size is clearly stated, indicating exactly how much product is supplied for the single treatment. It is a specific solution for petrol engines showing symptoms of carbon-related performance loss or for those seeking preventative maintenance.
