What fuel type should I use for my Ford S-Max?

I recently purchased a Ford S-Max and I'm not sure what fuel type I should be using. The manual says to use regular unleaded gasoline, but I've heard that premium gasoline can improve performance. What is your recommendation?

As a Ford car expert, I highly recommend sticking to regular unleaded gasoline for your Ford S-Max. Premium gasoline may have some benefits for performance, but it is not necessary and can be more expensive. Stick with the fuel type recommended by the manufacturer for optimal performance and cost-effectiveness.

I have been using premium gasoline in my Ford S-Max for years and have noticed a significant difference in performance. The extra cost is worth it for me. If you have the means, I would suggest trying out premium gasoline and see if you notice a difference.

I've been using regular unleaded gasoline in my Ford S-Max and have had no issues with performance. Stick with the recommended fuel type to avoid potential engine damage and save some money.
