Low-quality o r contaminated fuel can contribute to premature spark plug wear:

Carbon buildup: Poor-quality fuel can result in carbon buildup on the spark plug electrodes, leading to misfires and reduced spark plug life.
Dirty fuel: Contaminants like water o r dirt in the fuel can also cause excessive wear on spark plugs.

Fuel quality in Pakistan: Given that fuel quality can vary significantly, it’s a good idea to use reputable fuel stations and avoid filling up at stations with uncertain fuel quality.

Preventive tips:

Use fuel system cleaners periodically.
If possible, avoid driving on lower-quality o r old fuel.
Stick to higher-quality fuel brands that are known for better filtration and consistency.
