Some owners have reported suboptimal fuel economy, which may be due to:

ECU Calibration: Improper calibration of the Engine Control Unit ECU can affect fuel efficiency.

Software Updates: Outdated software may not optimize engine performance for local fuel quality and driving conditions.

Maintenance Issues: Neglecting regular maintenance, such as air filter replacement and spark plug servicing, can lead to decreased fuel economy.

Its recommended to have the vehicles ECU checked and updated by authorized service centers to ensure optimal fuel efficiency.
