What is the best way to maintain the performance of a Ford Mondeo engine?

I have noticed a decrease in performance of my Ford Mondeo engine. Can you provide some advice on how to maintain its performance?

Regularly changing the engine oil and keeping up with the recommended maintenance schedule is essential to maintaining the performance of your Ford Mondeo engine. Additionally, make sure to use high quality fuel and avoid overloading the vehicle.

Another important tip is to regularly check and replace the air filter. A clogged air filter can greatly hinder the performance of your engine.

You can also consider installing a performance chip or tuning your engine to improve its power and fuel efficiency. Just make sure to do thorough research and consult a professional before making any modifications.
