How does Pakistan’s fuel quality affect the Changan Karvaans catalytic converter performance?

Pakistani petrol sometimes contains higher sulfur content, which can damage o r clog catalytic converters. Could this be the main reason why Karvaan users face early converter failures?

Pakistani petrol often contains higher levels of sulfur, especially in remote areas o r from low-quality fuel stations. This:

Produces sulfates that coat the catalytic converter’s internal mesh

Reduces its ability to convert harmful gases

Leads to premature clogging o r failure

So yes, local fuel quality is a major contributor to Karvaan’s converter issues.
