Why am I experiencing trouble with my Kia Sorento's fuel efficiency?

I've noticed that my Kia Sorento's fuel efficiency has decreased significantly. What could be causing this issue and how can I improve it?

There are several factors that could be affecting your Kia Sorento's fuel efficiency, such as your driving habits, maintenance schedule, and air filter. I recommend checking your tire pressure regularly, getting a tune-up, and investing in a fuel injection cleaner.

It could also be a problem with your oxygen sensor or catalytic converter. These components are important for maintaining fuel efficiency. I suggest getting these checked by a mechanic and replacing them if necessary.

In some cases, a decrease in fuel efficiency could be due to a faulty fuel injector. I recommend getting this checked and replaced by a professional if needed. And remember to always use high-quality fuel for your Kia Sorento.
