Why Your Catalytic Converter Needs Attention

The catalytic converter is a critical emissions control component in your vehicle. Over time, carbon deposits, unburned fuel residue, and contaminants accumulate inside, reducing efficiency and increasing emissions. Regular use of a quality converter cleaner can extend the life of this expensive component and keep your vehicle running cleaner.

Frequently Asked Questions

Q: How does a catalytic converter cleaner work?

A: A catalytic converter cleaner is a fuel additive that you pour directly into your gas tank. As the treated fuel passes through the engine and exhaust system, its active cleaning agents break down and dissolve carbon deposits, soot, and contaminants that have accumulated inside the catalytic converter and combustion chambers. This helps restore the converter's efficiency and can reduce harmful emissions over time.

Q: Will this cleaner work on both gasoline and diesel engines?

A: Yes, the RayHong Catalytic Converter Cleaner is formulated to be compatible with most gasoline and diesel engines. Simply pour the 120ml into your fuel tank when your fuel level is around 1/4 remaining, then drive normally to allow the formula to circulate through the system.

Q: How often should I use the RayHong Catalytic Converter Cleaner?

A: For maintenance purposes, it is recommended to use the cleaner every 5,000–10,000 km. If you notice symptoms such as reduced fuel economy, a rotten egg smell, or a check engine warning related to the catalytic converter, you may apply it sooner as needed.

Q: Is it safe to use this product in my vehicle?

A: Yes. The product contains no high-concern chemicals and is designed for safe use in standard fuel systems. Always follow the usage instructions on the label and store in a cool, dry place away from heat sources and open flames, as with all fuel-related products.
