What should I do to increase the fuel efficiency of my Ford S-Max?

I recently purchased a Ford S-Max and I love everything about it, except for its relatively low fuel efficiency. I don't want to compromise on the power and comfort it provides, but I also want to save some money on gas. What are some ways I can increase the fuel efficiency of my Ford S-Max without sacrificing its performance?

Firstly, make sure your tires are properly inflated as underinflated tires can decrease fuel efficiency. Secondly, try to avoid excessive idling as it burns unnecessary fuel. Lastly, get your Ford S-Max serviced regularly to ensure all components are functioning optimally.

You can also try to decrease the weight of your car by removing any unnecessary items from your trunk. Additionally, using cruise control on the highway can help maintain a steady speed and save fuel. Don't forget to use the recommended grade of motor oil.

Another tip is to avoid aggressive driving which can significantly decrease fuel efficiency. Maintaining a consistent speed and avoiding sudden acceleration and braking can save you a lot of gas. Also, consider using a fuel additive to improve your car's performance.
