Motul Cat Convertor Cleaner EFS

Motul Cat Converter Cleaner EFS is a fuel additive built to clean the catalytic converter and related exhaust components in gasoline engines. It’s used by adding the product directly into your fuel tank where it mixes with petrol and works during engine operation to dissolve deposits and improve catalytic converter performance.

🔎 How It Works

• You mix the cleaner with fuel before a refill — typically one 300 ml bottle treats up to ~40–50 litres of gasoline.

• As the engine runs, the additive moves through the fuel system and exhaust stream, reaching the catalytic converter and oxygen (Lambda) sensors.

• It dissolves carbon deposits, resins, gum, and other buildup that reduce converter efficiency.

🚗 Main Benefits

Using this cleaner can:

• Restore engine power and performance that was lost due to clogged catalytic converter passages.

• Improve fuel efficiency by helping the converter and oxygen sensors work more effectively.

• Reduce engine knockings and stalls caused by exhaust restrictions or sensor contamination.

• Help lower harmful emissions by cleaning the exhaust treatment system.

📌 Where It’s Used

Motul Cat Converter Cleaner EFS is suitable for all gasoline engines equipped with catalytic converters, including:

• Cars with oxidation catalysts

• Engines with three‑way catalytic converters (TWC)

• Vehicles with oxygen sensors in the exhaust

It works with both naturally aspirated and turbocharged gasoline engines that use standard unleaded fuels.

🛠️ How to Use It

1. Add the bottle to your fuel tank before filling up with petrol.

2. Refuel normally so the cleaner mixes with the gasoline.

3. Drive the vehicle normally while the additive circulates and gradually cleans the catalytic converter and sensors.

For best results, use the product periodically as preventative maintenance or whenever performance and emissions issues appear.

🔍 Summary

Motul Cat Converter Cleaner EFS is a fuel‑soluble additive that targets carbon and deposit buildup in the catalytic converter and oxygen sensors. It helps restore performance, improve fuel economy, and maintain efficient emissions control by cleaning exhaust components while the engine runs.
