Why am I getting poor gas mileage in my Kia Niro?

My Kia Niro's gas mileage seems to be lower than what was advertised. What could be causing this issue? Is it something that can be fixed?

One common reason for poor gas mileage in Kia Niro is aggressive driving. Try driving more smoothly and avoiding hard accelerations and sudden braking. This can greatly improve your gas mileage.

Another potential cause is using the air conditioning excessively. Try using it only when necessary and keeping the temperature at a moderate level.

Check your tire pressure regularly, as underinflated tires can greatly affect gas mileage. Properly inflated tires can improve your gas mileage by up to 3%.

If the above suggestions do not improve your gas mileage, it's recommended to get your car checked for any potential mechanical issues. Factors such as a dirty air filter, faulty spark plugs, or a clogged fuel injector can also contribute to poor gas mileage.
