What is the best way to keep my Ford Fiesta's engine running smoothly?

My Ford Fiesta's engine seems to be running a bit rough lately. What can I do to keep it in top shape and prevent future issues?

Regular oil changes and using high quality motor oil is crucial for keeping your engine running smoothly. Additionally, make sure to follow the recommended maintenance schedule for your specific Fiesta model.

One thing to check is your spark plugs. Over time, they can become worn and dirty, which can affect engine performance. Replacing them regularly can improve engine performance and fuel efficiency.

You may also want to check your air filter. If it's clogged or dirty, it can restrict air flow to the engine and decrease performance. Make sure to replace it every 12,000-15,000 miles.

Finally, make sure to keep up with routine maintenance tasks such as checking and topping off fluids, replacing worn belts and hoses, and checking for any leaks. What may seem like small issues now can lead to bigger problems down the road.
