Why is my Kia Sportage's fuel economy decreasing?

I have noticed that my Kia Sportage's fuel economy has been decreasing recently. I used to get much better gas mileage, but now it seems like I can barely make it to the gas station without needing a refill. What could be causing this sudden decrease in fuel efficiency?

It is possible that your tires may be underinflated, causing your car to use more fuel to compensate for the added resistance. Check and adjust your tire pressure to the manufacturer's recommended levels.

Another potential cause could be a dirty air filter, which can restrict air flow and make your engine work harder, using more fuel. Make sure to replace your air filter regularly.

If you're experiencing a decrease in fuel economy while driving in urban areas, it could be due to excessive idling or stop-and-go traffic. Try to avoid heavy traffic and idling, and consider carpooling or using public transportation when possible.

Regular tune-ups and maintenance can also help improve your car's fuel efficiency. Make sure to keep up with scheduled maintenance such as oil changes, spark plug replacements, and fuel system cleanings.
