Is the Changan Karvaans catalytic converter getting clogged too early in Pakistan?

Many owners are experiencing performance s and increased fuel consumption, which mechanics link to a blocked catalytic converter. Is this due to local fuel quality, o r is the converter itself too sensitive for Pakistani conditions?

Yes, many Karvaan users have reported early clogging of the catalytic converter, typically before 50,000 km. The main causes are:

Poor fuel quality with high sulfur content

Excessive short trips and idling

Incomplete combustion due to bad spark plugs o r dirty air filters

The converter in the Karvaan may be too sensitive for local fuel and driving conditions, leading to restricted exhaust flow and performance .
