Why is my Ford Kuga's fuel economy decreasing?

I've noticed that my Ford Kuga's fuel economy has been steadily decreasing over the past few months. What could be the cause of this and what can I do to improve it?

You may be experiencing this issue due to clogged fuel injectors or a dirty air filter. I recommend bringing your car to a reliable mechanic for a tune-up.

It could also be a problem with your oxygen sensor or a faulty fuel pressure regulator. It's best to have a professional diagnose the issue.

Make sure you are also using the correct type of fuel and regularly checking your tire pressure. Small factors like these can also affect fuel economy.
