Catalytic converter cleaner fuel additive for petrol engines 120ml bottle, formulated with polyether amine, dodecane, fatty acid ester, and ferrocene to clean carbon deposits and restore engine efficiency
Catalytic converter cleaner 120ml fuel additive with polyether amine and ferrocene for petrol engines

Maintaining your vehicle's catalytic converter is a key aspect of preserving engine performance and fuel efficiency. This 120ml bottle of catalytic converter cleaner provides a straightforward method for addressing carbon deposit build-up within the exhaust system. It is formulated as a fuel additive, meaning you add it directly to your petrol tank where it mixes with fuel and circulates through the engine and exhaust. The specific blend of ingredients, including polyether amine, dodecane, and ferrocene, is designed to work on these deposits during normal driving, offering a practical maintenance solution without the need for workshop disassembly.
Features and Construction
This cleaner is presented as a ready-to-use liquid in a single 120ml bottle. The product's design centres on its chemical formulation and the convenience of its application method as a fuel additive.
Material and Build
The catalytic converter cleaner is a blended liquid formulation. Its composition includes polyether amine, dodecane, fatty acid ester, mineral oil, phosphate ester, and ferrocene. Each of these ingredients contributes to the product's function as a cleaning agent for petrol engine exhaust systems. The mixture is contained within a single 120ml bottle, which constitutes the full package contents for one treatment application.
Size and Practical Fit
The product is supplied in a 120ml bottle, a volume designed for a single treatment cycle in a standard petrol vehicle. This size makes it a compact addition to your vehicle maintenance kit and is straightforward to store. The entire contents of this one bottle are intended to be used in one go, added to a fuel tank with a low fuel level to ensure proper mixing and distribution throughout the system.
Uses and Placement
This cleaner has a specific use case for petrol-powered vehicles. Its application is integrated into the refuelling process, making it accessible for regular drivers.
Event or Professional Use
For vehicles subjected to frequent short journeys or stop-start traffic, which can accelerate carbon deposit formation in the exhaust, this cleaner offers a periodic maintenance option. It can be used as part of a scheduled service routine to help maintain catalytic converter efficiency, potentially supporting emissions system health.
Everyday Home Use
For the everyday motorist, this 120ml additive provides a simple, off-the-shelf solution for catalytic converter care. It requires no specialist tools or mechanical knowledge to use; you simply add the liquid to your fuel tank before filling up with petrol. The cleaner then works passively as you drive, making it a highly convenient method for attempting to restore lost performance or fuel economy linked to exhaust restriction.
Benefits and Buying Value
The value of this product lies in its targeted formulation and the practical simplicity of its use, offering a specific maintenance function for petrol engines.
Reuse and Low Maintenance
The product is a consumable one-time treatment supplied in a single 120ml bottle. There is no ongoing maintenance for the product itself. Its value proposition is the potential effect it may have on the vehicle's catalytic converter by cleaning internal deposits, which could contribute to sustained engine performance and fuel efficiency between uses.
Why Choose This Product
This catalytic converter cleaner presents a clear choice for drivers seeking a specific, formulated product for exhaust system maintenance. Its defined 120ml volume and listed ingredients, including polyether amine and ferrocene, provide transparency about what you are adding to your fuel system. It avoids the need for complex mechanical interventions by functioning as an in-tank additive, making it a practical first step for addressing symptoms of a partially blocked catalytic converter, such as reduced power or increased fuel consumption.
