Can I use regular unleaded gasoline in my Kia Sportage?

I've been using regular unleaded gasoline in my Kia Sportage for a few months now, but I'm starting to hear some strange noises from the engine. Should I continue using regular unleaded or switch to premium? I want to make sure I'm using the best fuel for my vehicle.

It is recommended to use premium gasoline in the Kia Sportage for optimal performance and fuel efficiency. Regular unleaded may cause engine knocking and potentially damage the engine over time.

I've been using regular unleaded in my Kia Sportage for years and haven't had any issues. However, if you are experiencing engine noises, it may be worth switching to premium to see if it improves.

Yes, you can use regular unleaded in your Kia Sportage, but keep in mind that it may not provide the best performance and could potentially cause issues with your engine.
