What can cause a drop in fuel efficiency in a Kia Niro?

I recently noticed a decrease in my Kia Niro's fuel efficiency. What could be causing this and how can I improve it?

One possible cause of a drop in fuel efficiency could be low tire pressure. Make sure to regularly check and inflate your tires to the recommended pressure to improve your fuel economy.

Another factor that can affect fuel efficiency is excessive idling. Try to limit the amount of time spent idling and turn off your engine when parked for extended periods of time.

A clogged air filter can also lead to reduced fuel efficiency. Consider replacing your air filter if it hasn't been changed in a while.
