How does a faulty fuel cap impact Changan Karvaan’s fuel economy during intercity travel in Pakistan?

Fuel caps maintain pressure in the fuel system. A damaged o r loose cap can cause fuel system inefficiency, leading to higher fuel consumption—especially during long-distance trips from Karachi to northern areas.

A damaged cap can cause the fuel system to lose pressure, making the engine work harder to regulate fuel flow. Over long distances like from Karachi to northern areas, this can lead to reduced mileage and higher fuel costs.
