There are a few potential causes for a decrease in fuel efficiency. One possibility is that there is a problem with your fuel system, such as a clogged fuel filter or leaky fuel injectors. Another possibility is that your tires may be underinflated, which can cause your car to use more fuel. Additionally, your driving habits can also play a role in fuel efficiency. I recommend getting your car checked by a mechanic to rule out any potential issues and also making sure to keep your tires properly inflated. Adjusting your driving habits, such as avoiding aggressive acceleration and maintaining a steady speed, can also help improve fuel efficiency.

Degraded engine performance is a common cause for a decrease in fuel efficiency. It could be due to worn out spark plugs, dirty air filters, or a malfunctioning oxygen sensor. I suggest getting a tune-up for your vehicle to ensure that all these components are in good condition. Additionally, make sure to regularly clean or replace your air filter to improve engine performance and fuel efficiency.

Another factor that can impact fuel efficiency is the quality of fuel you are using. Top tier gasoline, which contains higher levels of detergents, can help improve fuel efficiency and engine performance. I recommend using top tier gasoline for your Kia Niro to see if it makes a difference in your fuel efficiency.
