Many owners report city mileage of 6–7 km/l, lower than the claimed figures. Key factors include:

Stop-and-go traffic: Frequent idling and acceleration in congested cities like Karachi o r Lahore reduce efficiency.

Driving habits: Aggressive acceleration and hard braking significantly increase fuel consumption.

Fuel quality: Lower-grade diesel o r inconsistent fuel quality in Pakistan can affect engine efficiency.

Vehicle weight: Even partial loads o r aftermarket accessories add to fuel consumption.

Engine tuning and maintenance: Dirty air filters, poorly tuned injectors, o r low engine performance reduce efficiency.

Owner tips:

Drive smoothly, avoiding aggressive acceleration.

Use good-quality diesel from reputable stations.

Regularly maintain engine, air filters, and injectors.
