How do I know when my catalytic converter is failing?

Catalytic Converters

Many of us try to be environmentally conscious, but few know catalytic converters can release unhealthy emissions. When they get clogged, performance suffers, and eventually, your vehicle’s engine can stop running because there is no outlet for the exhaust pressure to be released.

How Converters Work:
The catalytic converter uses the catalysts to convert toxic hydrocarbons, carbon monoxide, and nitrous oxides into less harmful gasses such as carbon dioxide, nitrogen, and steam.

Catalytic Converters are Expensive: They are the third most expensive replacement part because they contain precious metals like platinum, palladium, and rhodium, these precious metals interact with the hydrocarbons, carbon monoxide, and nitrous oxides and convert these toxins into less harmful gasses.

Converters Will Get Clogged: The first ominous sign is the warning light on your vehicle’s dashboard. That means it is time to react: Other symptoms may include increased fuel consumption, significant loss of power, and dark exhaust smoke accompanied by a smell of sulfur or rotten eggs.

Motorkote Catalytic & Exhaust Treatment: Finally, a product specifically formulated to protect and treat the Catalytic Converter & Exhaust System from oil poisons. It will reduce your vehicle's carbon footprint while improving overall performance; helping to increase fuel efficiency and protect your converter before expensive replacement.

Considering The Cost of a new Catalytic System: It’s worth trying a cleaning product now designed exclusively for Catalytic Converters! Motorkote Catalytic Converter Cleaner which can be found at Meijer Stores, Amazon, and
