How to maintain the performance of a Ford Fiesta engine?

I have noticed a decrease in the acceleration and overall performance of my Ford Fiesta's engine. What steps can I take to ensure its performance and longevity?

Regularly changing the oil and keeping it at the recommended level is crucial for the engine's performance and longevity. Also, make sure to check and replace any faulty spark plugs or air filters.

Taking your Fiesta to a certified mechanic for routine maintenance is a great way to ensure its performance. They can catch any potential issues early on and keep your engine running smoothly.

In addition to regular maintenance, be mindful of your driving habits. Avoid harsh acceleration and deceleration, as well as prolonged idling, to prevent unnecessary strain on the engine.
