Yes, fuel quality in Pakistan is a major issue for European engines, especially:

Low RON fuel mostly RON 87–92 available causes engine knocking.

Adulterated o r dirty fuel clogs injectors and damages sensors.

Turbocharged engines tuned for RON 95+ suffer performance and efficiency loss.

Preventive Measures:

Use Hi-Octane fuel from reputable brands like Shell V-Power, PSO, o r Total.

Regularly use fuel injector cleaners o r additives every 5,000–10,000 km.

Clean fuel filter and injectors more frequently than the EU schedule.
