How Long dose a catalytic converter last

How long can a new catalytic converter be used in a car?

A new catalytic converter can be used in a car for around 10 years or 100,000 miles, on average. However, the exact lifespan can vary depending on a number of factors, including:

• The make and model of the car

• Driving conditions (e.g., city vs. highway driving)

• Maintenance habits (e.g., regular oil changes and tune-ups)

• Fuel quality

Here are some specific data on the lifespan of catalytic converters, from various sources:

• A study by the National Institute of Standards and Technology found that catalytic converters in passenger cars typically last between 80,000 and 120,000 miles.

• A study by the Automotive Aftermarket Industry Association found that the average lifespan of a catalytic converter is 10 years.

• A study by the California Air Resources Board found that catalytic converters in light-duty vehicles typically last between 70,000 and 150,000 miles.
