Why is it important to regularly change the oil in the Ford Fiesta?

I've heard that oil changes are necessary for maintaining the health and longevity of a car's engine. But why is it specifically important for the Ford Fiesta? What issues could arise if I don't change the oil regularly?

Regular oil changes are crucial for any vehicle, but particularly for the Ford Fiesta. Over time, oil can become contaminated with debris and lose its effectiveness in lubricating and protecting the engine. This can lead to increased wear and tear on engine components, potentially leading to costly repairs.

Not changing your oil can also cause a build-up of sludge in the engine, which can restrict oil flow and decrease engine performance. In severe cases, this can even lead to engine failure.
