Why is my Kia Stonic's fuel economy performance not as good as advertised?

I recently purchased a Kia Stonic and I'm noticing that the fuel economy is not as good as the advertised numbers. I'm getting significantly lower miles-per-gallon than what was promised. What could be causing this issue?

There could be several reasons why your Kia Stonic's fuel economy is lower than expected. First, make sure you are properly inflating your tires and regularly changing your air filter. This can greatly affect your fuel efficiency. Additionally, try to avoid aggressive driving and keep a consistent speed while on the highway. If these steps do not improve your fuel economy, it may be worth taking your vehicle to a mechanic to check for any potential issues.

I had a similar issue with my Kia Stonic and found out that my fuel injectors were clogged. I suggest getting them professionally cleaned or replaced if necessary. Also, check your oil levels and make sure they are at the recommended levels for your vehicle.

I've noticed that my Kia Stonic's fuel economy is affected by the type of gas I use. I recommend using a higher quality gasoline to see if that improves your fuel efficiency.
