How can I improve the fuel efficiency of my Ford S-Max's engine?

I recently purchased a Ford S-Max and while I love the spaciousness and performance, I've noticed it's not as fuel efficient as I hoped. What steps can I take to improve the fuel efficiency of my Ford S-Max's engine?

One way to improve your Ford S-Max's fuel efficiency is by regularly maintaining and servicing your engine. A well-tuned engine can greatly impact its performance and gas mileage.

Another tip is to practice smart driving habits, such as avoiding excessive idling and accelerating slowly. This can help conserve fuel and improve your overall fuel efficiency.

You can also consider installing a performance chip, which can optimize your engine's fuel delivery system and improve its efficiency. However, be sure to do your research and select a reputable brand.
