Could low-quality fuel o r adulterated petrol in Pakistan be a major factor in Alsvin’s poor fuel consumption?

Are Changan Alsvin engines sensitive to poor fuel quality, which is common at unbranded o r rural petrol stations?

Yes. Changan’s BlueCore engines are tuned for cleaner RON 91+ fuels. In Pakistan:

Adulterated fuel kerosene-mixed o r water-contaminated can trigger incomplete combustion

Results in carbon buildup, knocking, and reduced mileage

Alsvin engines lack adaptive knock control, so fuel quality matters more
Use fuel from reputed stations PSO, Total, Shell and avoid unbranded rural pumps.
