Catalytic converter cleaner is designed for simple fuel-tank use. Always follow the label on the bottle and confirm that the product is suitable for your vehicle and fuel type before use.
Basic steps
- Start with a gasoline-powered vehicle and a fuel level that matches the product directions.
- Pour the cleaner into the fuel tank as directed.
- Drive normally so the product can move through the fuel and exhaust path.
- Monitor the vehicle after the tank is used and avoid repeatedly clearing codes without understanding why they return.
When to be cautious
If the vehicle has severe misfires, strong exhaust odor, overheating, rattling converter noise, or drivability problems, cleaner should not replace inspection. Those symptoms can point to issues that need service.
