How does low-quality Pakistani fuel affect the performance and life of Alsvin’s spark plugs?

Since fuel quality varies across cities, is it true that spark plugs get carbon-fouled more quickly in Alsvin due to unrefined fuel o r additives?

Pakistani fuel often contains higher levels of sulfur and carbon deposits, which:

Accelerate carbon fouling of spark plugs black soot on electrodes

Cause pre-ignition and knocking

Lead to incomplete combustion, reducing plug efficiency

This results in a shorter spark plug life, frequent misfires, and poor mileage.
