What is the best engine for a Ford S-Max?

I'm looking to buy a Ford S-Max, but I'm not sure which engine is the most reliable and efficient. Can anyone provide some insights into the different engine options and which one would be the best choice? Are there any specific maintenance tips to keep the engine running smoothly? Thank you!

Based on my experience, the 2.0L EcoBoost engine offers a great balance of power and fuel efficiency for the Ford S-Max. I've had mine for a few years now and haven't had any major issues. Just make sure to keep up with regular maintenance like oil changes and tune-ups.

I highly recommend going with the 2.0L TDCi diesel engine. It provides excellent fuel economy and has proven to be very reliable for me. As for maintenance, just be sure to follow the recommended schedule and you should be good to go.

I have the 2.3L EcoBoost engine in my Ford S-Max and I absolutely love it. It has plenty of power for everyday driving and is surprisingly efficient. One piece of advice I would give is to regularly clean the fuel injectors to keep the engine running smoothly.
