How to Improve Engine Performance in the Ford S-Max?

I have been experiencing a decrease in engine performance in my Ford S-Max. What steps can I take to improve it?

One of the best ways to improve engine performance in your Ford S-Max is to regularly maintain and replace the air filter. A clean air filter allows for better air flow and can increase horsepower.

Using a high-quality fuel and regularly checking and changing the spark plugs can also greatly improve engine performance in your Ford S-Max. These components directly affect the combustion process and can lead to a smoother and more efficient engine.

Another helpful tip is to regularly change the oil in your Ford S-Max. Old or dirty oil can lead to engine sludge and can decrease performance. Be sure to follow the manufacturer's recommended schedule for oil changes.
