Wynns Catalytic & Oxygen Cleaner 500ml

Part Number: WYN25692

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 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 warning lights.

Product Characteristics

• Restores catalytic converter efficiency by removing carbon buildup.
• Improves oxygen sensor response and accuracy.
• Helps resolve emissions-related warning lights and fault codes.
• Supports emissions system performance and engine response.
• Assists in preventing premature catalytic converter failure.
• Helps maintain optimal emissions control over time.
• Safe for all gasoline engines, including GDI and turbocharged.
• Cost-effective alternative to replacing expensive emissions components.

Storage & Shelf Life: Store in a cool, dry place in tightly closed original packaging. Protect from frost and direct sunlight. Shelf life 5 years from production date.

How to Use

• Add entire 500ml bottle to a nearly empty fuel tank before refilling with petrol.
• Drive normally to allow the cleaner to circulate through the system.
• For severe contamination: use one bottle to 40 litres for stronger cleaning.
• For preventative care: apply every 3,000–5,000 miles or every third tank of fuel.

 

Particularly effective for restoring emissions components in high-mileage vehicles or when check engine lights are triggered by oxygen sensor or catalyst inefficiency. For enhanced emissions reduction, use in combination with Wynns Extreme Petrol Emissions Reducer 325ml.
