Wynns Catalytic & Oxygen Cleaner is a specialized fuel treatment designed to clean and restore the efficiency of catalytic converters and oxygen sensors in gasoline engines. This advanced 500ml formula contains carefully selected cleaning agents and fuel modifiers that help remove carbon and contaminant buildup from the catalytic converter substrate and oxygen sensor surfaces. Regular use helps maintain emissions system performance, extend component life, and resolve emissions-related check engine lights and failed emissions tests.

Key Features

• Catalytic Converter Restoration: Removes performance-robbing deposits from catalyst surfaces
• Oxygen Sensor Cleaning: Improves sensor response time and accuracy
• Emissions Reduction: Lowers harmful exhaust emissions including HC, CO, and NOx
• Check Engine Light Resolution: Helps address emissions-related fault codes
• Combustion Optimization: Improves fuel burn efficiency and reduces unburned fuel
• Catalyst Life Extension: Helps prevent premature converter failure
• Performance Improvement: Restores lost power due to restricted exhaust flow
• Fuel Economy Enhancement: Improves MPG by optimizing combustion and sensor function
• Preventative Maintenance: Regular use helps maintain emissions system efficiency
• Emissions Test Assistance: Helps vehicles pass emissions inspections

How to Use

Add entire contents to a nearly empty fuel tank before refilling with gasoline. One 500ml bottle treats up to 60 liters of fuel. Drive normally to allow the treatment to work through the fuel system and reach the catalytic converter and oxygen sensors. For addressing existing problems, use at a higher concentration (one bottle to 40 liters) and drive the vehicle under various load conditions including highway driving to ensure the catalytic converter reaches proper operating temperature. For preventative maintenance, use every 3,000-5,000 miles. For emissions test preparation, use one week before testing.

Catalytic & Oxygen Cleaner is particularly valuable for high-mileage vehicles, vehicles with emissions-related check engine lights, or vehicles that have failed emissions tests. The formula is safe for all gasoline engines including those with turbochargers and direct injection systems. For comprehensive emissions system maintenance, consider combining with Wynns Extreme Petrol Emissions Reducer for maximum effectiveness. This product is not suitable for diesel engines; use Wynns Diesel Particulate Cleaner for diesel emissions systems.
