120ml Catalytic Converter Cleaner Liquid Fuel Additive Treatment

This catalytic converter cleaner is a liquid fuel additive treatment supplied in a single 120ml bottle. Its formulation is designed to be added directly to a vehicle's fuel tank, where it circulates through the fuel system and into the exhaust to help clean the catalytic converter. The product contains a specific blend of ingredients, including polyether amine, dodecane, fatty acid ester, mineral oil, phosphate ester, and ferrocene, which work together during the combustion and exhaust process. It is intended for use with standard petrol or diesel fuels as a maintenance treatment or to address symptoms that may be related to a restricted or fouled catalytic converter, such as reduced engine performance or increased emissions.

Features and Construction

This product is defined by its liquid formulation and the specific ingredients listed for its intended cleaning action within the vehicle's exhaust system.

Material and Build

The cleaner is a liquid chemical blend. The stated active ingredients are polyether amine, dodecane, fatty acid ester, mineral oil, phosphate ester, and ferrocene. This combination is typical for fuel additives targeting carbon and soot deposits within the exhaust system, particularly on the substrate of the catalytic converter. The product is supplied in a sealed 120ml bottle, which contains a precise volume of treatment for a single application during a fuel fill-up.

Size and Practical Fit

The product is packaged as a single 120ml bottle. This volume is a standard treatment size designed to be poured entirely into a vehicle's fuel tank, typically when filling with a significant amount of fuel, such as during a routine visit to the petrol station. The compact bottle is easy to store and handle, allowing for straightforward application without the need for measuring or mixing.

Uses and Placement

This additive has a clear, singular application process and is intended for a specific automotive maintenance task.

Event or Professional Use

This product can be used as part of a scheduled vehicle maintenance routine, often recommended at specific mileage intervals by some service guides or additive manufacturers to help prevent catalytic converter clogging. It may also be used proactively before an emissions test, or reactively if symptoms of a partially blocked converter are noticed, such as a loss of engine power, particularly at higher speeds, or a sulphur-like odour from the exhaust.

Everyday Home Use

For the average motorist, this 120ml bottle provides a simple, one-step treatment. The process involves unscrewing the fuel cap, pouring the entire bottle contents into the tank, and then refuelling with petrol or diesel as normal. It requires no specialist tools or mechanical knowledge, making it an accessible form of preventative maintenance that can be performed at home or at the forecourt.

Benefits and Buying Value

The value of this product lies in its targeted function and the convenience of its application format.

Reuse and Low Maintenance

The product is a single-use treatment supplied as one 120ml bottle. It is not a permanent modification but a periodic maintenance item. Its low-maintenance appeal comes from the simplicity of application—simply add it to the fuel—and the potential to help maintain the efficiency of an existing catalytic converter, which is a costly component to replace if it fails.

Why Choose This Product

This catalytic converter cleaner offers a specific formulation with disclosed ingredients (polyether amine, dodecane, fatty acid ester, mineral oil, phosphate ester, ferrocene) and a clear, convenient 120ml application size. It provides a direct solution for motorists seeking a fuel-additive-based approach to exhaust system maintenance. The choice is based on the need for this specific type of treatment and the practicality of the ready-to-use bottled format.
