What is the importance of regular oil changes in a Ford Fiesta?

I have a Ford Fiesta and recently I have been skipping oil changes to save money. However, I've been hearing conflicting opinions on whether or not it's actually necessary. Can someone explain the importance of regular oil changes in a Ford Fiesta?

Regular oil changes are essential for the health and longevity of your Ford Fiesta's engine. Skipping them can lead to costly repairs down the line.

I used to skip oil changes too, but after my engine failed and I had to shell out thousands of dollars, I learned my lesson. Don't make the same mistake.

Oil changes are like getting a regular check-up for your car. It helps prevent any potential issues and keeps your engine running smoothly.
