Why is the fuel efficiency of my Kia Niro lower than the advertised MPG?

I just bought a Kia Niro and noticed that I am not getting the advertised MPG. What could be causing this and how can I improve my fuel efficiency?

One reason why you may not be getting the advertised MPG is because your driving habits and environmental factors, such as weather and traffic, can greatly affect fuel efficiency. Additionally, regularly maintaining your vehicle, such as checking tire pressure and getting regular oil changes, can also improve your fuel efficiency.

Another factor that can impact fuel efficiency is the type of roads you typically drive on. If you frequently drive on hilly terrain or in highly congested areas, this can decrease your MPG. Consider adjusting your route or driving habits to improve your fuel efficiency.

Additionally, your driving style can also affect fuel efficiency. Avoid frequent and aggressive acceleration and braking, and try to maintain a steady speed on the highway. This can greatly improve your MPG and save you money on gas.
