Pakistani fuel often contains high levels of sulfur and other impurities, which can significantly reduce the lifespan and efficiency of the catalytic converter:

Sulfur Deposits: High sulfur levels can lead to the formation of sulfuric acid in the converter, damaging the catalyst material and clogging it over time.
Impurities: Low-quality fuel may contain contaminants that build up within the converter, decreasing its efficiency and causing it to fail prematurely.

Precautions:

Use premium-quality fuel whenever possible, preferably from reputable stations that have additives to reduce sulfur content.
Consider using a fuel additive designed to clean the fuel system and minimize contaminants.
