Is Adding a Three-Way Catalytic Cleaner Useful?
2 Answers
Adding a three-way catalytic cleaner is useful. Below is an introduction to the three-way catalytic cleaner: 1. Efficacy of the three-way catalytic cleaner: The efficacy of the three-way catalytic cleaner is to remove sulfur, phosphorus, and other chemicals from the surface of the three-way catalytic converter, unclog blocked exhaust pipes, and restore the activity of the three-way catalytic converter. For more severe blockages, disassembly and cleaning may be necessary. 2. Function of the three-way catalytic cleaner: The three-way catalytic converter is the most important external purification device installed in the automobile exhaust system. It can convert harmful gases such as carbon monoxide, hydrocarbons, and nitrogen oxides emitted by automobile exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction. Since this converter can simultaneously convert the three main harmful substances in the exhaust into harmless substances, it is called a three-way converter.
I remember the technician mentioned during the last service that the catalytic converter cleaner is indeed useful but depends on the situation. For vehicles with mild clogging, adding it can help alleviate the issue, especially for cars prone to carbon buildup due to long-term city driving at low speeds. The operation is simple—just pour it into the fuel tank before refueling and run through a full tank of gas, with better results when driving on highways. However, if the car already has the check engine light on or fails emission tests, it's likely severely clogged. In such cases, adding ten bottles won't help, and you must remove and clean or replace it. For prevention, it's recommended to add one bottle every 20,000 kilometers, which is much more cost-effective than spending thousands later to replace the catalytic converter.
