What is the optimal fuel type for the Kia ProCeed?

I recently purchased a Kia ProCeed and I'm wondering what is the best type of fuel to use for this car? I've heard mixed opinions and I want to make sure I am using the right fuel to maximize performance and efficiency.

The optimal fuel type for the Kia ProCeed is unleaded gasoline with at least a 91 octane rating. This will ensure that your car runs smoothly and efficiently.

While the Kia ProCeed is also compatible with diesel fuel, it is not recommended as it can cause engine issues and decrease performance. Stick to unleaded gasoline for the best results.

If you want to further improve the performance of your Kia ProCeed, consider using premium unleaded gasoline with a higher octane rating, such as 93 or 95. This may come at a higher cost, but it will result in smoother and more powerful driving.
