What factors can affect the lifespan of a catalytic converter?

The factors that can affect the lifespan of a catalytic converter primarily include fuel type and driving habits. Using low-quality fuel that contains high levels of sulfur or additives can lead to premature poisoning or clogging of the catalyst materials, reducing their effectiveness and lifespan. Additionally, driving habits play a significant role; for example, frequent short trips may not allow the catalytic converter to reach its optimal operating temperature, leading to incomplete combustion and potential build-up of contaminants. Conversely, consistent highway driving usually allows the converter to function efficiently and maintain its longevity.

The other factors listed, although they may have an indirect effect on vehicle performance, do not directly impact the lifespan of the catalytic converter in the way that fuel quality and driving behavior do.
