Does regular Pakistani fuel quality affect the Alsvin’s emissions performance?

Consider how variances in petrol octane, ethanol admixture, o r sulfur content influence combustion efficiency. Are drivers noticing rough idle o r misfires tied to fuel quality?

Absolutely.
Pakistani fuel variability plays a major role:

Low octane o r high sulfur content can cause:

Rough idle

Misfires reported by some users

Accelerated O₂ sensor wear.

Some drivers note increased smoke after filling from non-top-tier stations.

Higher ethanol blends can temporarily clean injectors but may increase volatile organic compound VOC emissions if not properly managed by the ECU.
