The catalytic converter, which converts harmful emissions into harmless gas, often lasts 10 years or longer and should be replaced only when needed. It can become clogged, physically damaged, or contaminated by oil or engine coolant. It can also overheat.
How many miles can a catalytic converter last?
The average catalytic converter is designed to last about 100,000 miles, so if your car is nearing six figures on the odometer, chances are you need to give some thought to your catalytic converter.
Can catalytic converters last 200000 miles?
The average catalytic converter has a lifespan of about ten years. Most catalytic converters last between 70,000 to 100,000 miles in a vehicle before they need replacing.
How do I know if my catalytic converter needs to be replaced?
Among the symptoms of a bad catalytic converter are: Sluggish engine performance. Reduced acceleration. Dark exhaust smoke. The smell of sulfur or rotten eggs from the exhaust. Excessive heat under the vehicle.
Can a catalytic converter last 20 years?
A typical catalytic converter can supposedly last for up to 10 years or more. But generally, these components are designed to last the life of the vehicle.
Is catalytic converter worth replacing?

Does a 20 year old car need a catalytic converter?
Technically, yes. Older cars ran just fine before catalytic converters became commonplace in the 1970s. Another problem is that removing the light-off catalyst (the one closest to the engine) from a modern car (newer than 1996) will trigger the check engine light due to the OBD 2 catalyst efficiency monitor.
Can a catalytic converter last 300000 miles?
Assuming that the car is maintained properly, I have found cats to last between 250,000 and 300,000 miles. The failure point for a well-maintained cat is usually mechanical in nature.
What happens if I don’t replace my catalytic converter?
If it has begun to flow poorly due to being clogged up, it will cause the vehicle to run extremely poorly. The vehicle will lack power and fuel economy. In extreme cases, the catalytic converter can overheat and cause components on the undercarriage to combust, melt, smolder, or catch fire.
What does a failing catalytic converter sound like?
Rattling Noises. Your catalytic converter consists of small, honeycomb-shaped components that can cause a rattling sound when broken. If your catalytic converter is broken, this rattling should be loudest when the car starts, and should get worse over time.
How do you fix a catalytic converter without replacing it?
Fuels and Fuel Additives For example, if you typically fill your vehicle with the cheapest low-octane fuel, try running your vehicle on a few tanks of high-octane fuel. Adding one gallon of lacquer thinner to ten gallons of gas at your next refuel may also be effective clearing out catalytic converter deposits.
How long do cheap catalytic converters last?
In the case of the catalytic converter, if you buy a cheap one, it’s not going to convert the exhaust gases as much. A cheap catalytic converter may work for a while. In our experience, we have found that they’re good for about a year to maybe two years.
What causes catalytic converter failure?
Possible causes are an improper fuel mixture, incorrect timing, bad spark plugs, a malfunctioning oxygen sensor, sticking float, defective fuel injector or a faulty check valve. Oxygen Sensor Not Functioning Properly. Too rich and the catalyst can melt down from fuel burning inside the converter.
What are the 3 most leading failures of a catalytic converter?
Most catalytic converter failures fall under one of three categories: Overheated, melted or broken converters. Coated/oil-fouled substrate.
How many catalytic converters are in a car?
Most cars will have one catalytic converter. If you have a car with a dual exhaust system, however, your car will have two catalytic converters. If your catalytic converter needs to be replaced, you may notice one or more of these warning signs: Your check engine light is on.
Can your car work without a catalytic converter?
Your catalytic converter is named as such because it converts toxins into less harmful byproducts, such as water vapor and carbon dioxide. Without this component, your vehicle will no longer be filtering and reducing harmful emissions, including hydrocarbons, nitrogen oxides, and carbon monoxide.
What are the symptoms of a clogged up catalytic converter?
4 Signs of a Clogged Catalytic Converter Check Engine Light. When your check engine light suddenly turns on, this is a sure sign that something is wrong with your vehicle – and it could be the catalytic converter. Stalled or Difficult to Start Engine. Poor Fuel Economy. Failed Emissions Test.
Why is it so expensive to replace a catalytic converter?
The converter uses specific expensive metals, which not only help keep the exhaust clean, but it promotes the longevity of this part. So to put it simply, replacing the catalytic converter is expensive because it can be a bit finicky to replace on some model, but mainly because it’s made of precious metals.
How often do I need to replace my catalytic converter?
