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

I am considering buying a Ford S-Max and have heard some mixed opinions about the different engines. Which engine is the most reliable and long-lasting in the Ford S-Max? Are there any specific maintenance tips or advice I should know about?

In my experience with Ford S-Max, the 2.0L EcoBoost engine has been the most reliable. It's efficient, powerful, and built to last. However, make sure to schedule regular maintenance check-ups and always use high-quality oil for best results.

I have personally found the 1.5L EcoBlue diesel engine to be the most reliable. It's incredibly fuel-efficient and has a longer lifespan compared to other engines. Just remember to change your air and fuel filters regularly and it should serve you well for years to come.

My brother has a Ford S-Max with the 2.0L TDCi diesel engine and he has had no major issues with it. Just remember to follow the recommended maintenance schedule and clean your EGR valve every 50,000 miles to ensure optimal performance.
