Pakistan’s fuel quality, with higher sulfur content and impurities, can cause spark plug fouling and premature wear:

Fouling: Impurities in low-quality fuel can lead to the formation of carbon deposits on the spark plug electrodes, which can cause misfires and poor performance.
Pre-Ignition: Poor fuel quality can also cause pre-ignition when the air-fuel mixture ignites before the spark plug fires, leading to excessive wear on the spark plugs and engine components.
Reduced Lifespan: Over time, low-quality fuel accelerates the degradation of spark plugs, requiring more frequent replacements.

Precautions:

Use premium fuel from reputable stations, even if its more expensive.
Consider using a fuel additive designed to clean the fuel system and reduce the buildup of impurities.
Keep fuel filters and injectors clean to minimize contaminants.
