Why is my Kia Niro's fuel economy dropping?

I've noticed that my Kia Niro's fuel economy has been decreasing over time. I used to get great mileage, but now it seems like I need to fill up more often. What could be causing this and how can I improve my fuel economy?

First, make sure you are regularly maintaining your vehicle. Check your tire pressure, change your oil and air filter as needed, and get tune-ups when necessary. It could also be helpful to adjust your driving habits, such as avoiding aggressive acceleration and maintaining a consistent speed. And of course, make sure you are using the recommended grade of fuel for your Kia Niro.

Another factor to consider is your driving environment. If you are frequently driving in stop-and-go traffic or on hilly terrain, this can negatively impact your fuel economy. Take note of your driving patterns and try to anticipate traffic to improve efficiency.

Have you made any modifications to your vehicle, such as installing a roof rack or larger tires? These can increase drag and decrease fuel economy. Consider removing unnecessary additions to improve efficiency.

It's also important to consider your own driving habits. Are you idling for long periods of time or taking city routes instead of highways? These can also contribute to lower fuel economy. Try to plan your routes and avoid idling to maximize efficiency.
