Are Pakistani fuel conditions contributing to faster spark plug wear in Changan Kalam?

Low-octane and adulterated petrol may cause incomplete combustion, leading to carbon buildup on spark plugs. Is this a root cause of the issue?

Absolutely — this is a major factor.

Adulterated petrol o r low-octane fuel leads to:

Incomplete combustion

Carbon fouling on spark plugs

Pre-ignition and knock which damages the electrodes

Frequent fuel problems cause spark plugs to degrade much earlier than their expected life.

➡️ Use high-octane fuel if possible and avoid unknown fuel stations.
