How do I properly maintain the engine of a Ford Fiesta?

I recently purchased a Ford Fiesta and want to make sure I am properly maintaining the engine to ensure its longevity and performance. What are some important steps I should take and things I should know about maintaining a Ford Fiesta's engine?

Regularly changing the oil and oil filter is crucial for the health of your Ford Fiesta's engine. I recommend changing it every 5,000-7,500 miles depending on your driving habits.

In addition to oil changes, it's important to also replace the air filter about every 12,000-15,000 miles. This will help keep your engine running smoothly and efficiently.

Checking and replacing your spark plugs at the recommended interval is key to maintaining the performance of your Ford Fiesta's engine. This will ensure proper combustion and power.
