What is the most reliable engine type for a Ford S-Max?

I've heard mixed opinions about the engines in the Ford S-Max. I want to make sure I choose a reliable one. Can anyone give me some advice on the best engine type for this car?

In my experience, the EcoBoost engine has been the most reliable and efficient option for the Ford S-Max. I would highly recommend it.

I personally prefer the diesel engine for its durability and fuel efficiency. I've had mine for years and it's still running smoothly.

I suggest doing some research on the different engine types and their pros and cons to find what works best for you. It's important to consider your usage and driving habits.
