120ml Catalytic Converter Cleaner: Fuel Additive for Petrol and Diesel Engines

This catalytic converter cleaner is a 120ml liquid fuel additive designed for use in both petrol and diesel vehicles. Its formulation aims to address carbon deposit build-up within the catalytic converter, a key component for managing exhaust emissions. The product contains a blend of active ingredients, including polyether amine and dodecane, which work through the fuel system. It is supplied as a single 120ml bottle, providing a one-time treatment that is added directly to the vehicle's fuel tank. This cleaner offers a maintenance option for motorists looking to help maintain their emissions system without the need for specialist tools or dismantling.
Features and Construction
The cleaner is presented as a 120ml liquid formulation, packaged for straightforward consumer use. Its construction centres on a specific chemical blend developed for fuel system cleaning applications, targeting deposits within the catalytic converter.
Material and Build
The product is a liquid cleaner formulated with a blend of ingredients: polyether amine, dodecane, fatty acid ester, mineral oil, phosphate ester, and ferrocene. This combination is typical for fuel additive cleaners designed to dissolve and disperse carbon-based deposits. The formulation is housed in a single 120ml bottle, which constitutes the complete package contents for one application.
Size and Practical Fit
The product's 120ml volume is a standard size for single-treatment fuel additives. This amount is designed to be added to a vehicle's fuel tank, typically when the fuel level is low, and is suitable for the fuel tank capacity of most cars and vans. The packaging is compact for easy storage and handling.
Uses and Placement
This cleaner is intended for periodic maintenance of a vehicle's catalytic converter and related fuel system components. It is aimed at petrol and diesel vehicle owners seeking to perform preventative maintenance on their emissions control systems.
Event or Professional Use
While suitable for general consumer use, the product can also be utilised as part of a broader vehicle maintenance schedule, potentially by owners performing their own upkeep or in less formal workshop settings. Its application is a single event, involving adding the bottle's contents to the fuel tank prior to refuelling.
Everyday Home Use
For the everyday motorist, this cleaner provides a relatively simple maintenance task. The process involves adding the 120ml liquid to the fuel tank, a procedure that requires no specialist tools or mechanical knowledge, aligning with routine at-home vehicle care.
Benefits and Buying Value
The primary value offered is the potential to help maintain catalytic converter function through cleaning, using a single, ready-to-use application. The product provides a specific tool for this aspect of vehicle maintenance.
Reuse and Low Maintenance
The product is a single-use item; the 120ml bottle contains enough cleaner for one treatment. Its value in maintenance stems from its intended function as part of an occasional cleaning regimen, not from ongoing reuse of the product itself.
Why Choose This Product
This cleaner presents a focused option for motorists specifically concerned with catalytic converter maintenance. Its 120ml volume and stated formulation for petrol and diesel engines provide clear parameters for its use, offering a defined solution within the wider category of fuel system additives.
