Why is the gas mileage on my Kia Soul dropping?

I used to get great gas mileage on my Kia Soul, but recently it seems to be dropping. What could be causing this decrease in fuel efficiency?

It could be due to a number of factors such as low tire pressure, dirty air filter, or a faulty oxygen sensor. Have you checked these things?

Have you recently changed your driving habits or routes? Driving at high speeds or on hilly roads can also affect gas mileage. It's important to drive efficiently and plan your routes to save on gas.

Another possibility is that there is an issue with the fuel injectors or spark plugs. These can become clogged or worn over time, causing a decrease in fuel efficiency. It may be worth getting these checked by a mechanic.
