Why does my Hyundai Tucson’s fuel efficiency suddenly?

I’ve noticed that my Tucson’s mileage has decreased significantly over the past few weeks. What common performance issues could cause poor fuel economy in Pakistani driving environments?

A sudden in mileage can be due to:

Underinflated tires increasing rolling resistance.

Dirty air o r fuel filters reducing combustion efficiency.

Malfunctioning oxygen sensors o r faulty fuel injectors causing rich fuel mixtures.

Excessive idling o r aggressive driving in city traffic.
Checking tire pressure, regular filter changes, and engine diagnostics can help restore fuel economy.
