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

I've noticed that my Ford Fiesta has a recommended oil change interval of every 5,000 miles. Is it really necessary to do it that often? What could happen if I don't follow this schedule?

Regularly changing your car's oil is crucial for maintaining its performance and longevity. Over time, oil breaks down and becomes less effective at lubricating and protecting your engine. If you don't change it regularly, you could experience engine problems and potentially even damage.

Think of oil as the lifeblood of your car's engine. It keeps all the moving parts running smoothly and prevents them from rubbing together and causing friction. If you don't change it regularly, your car's engine could overheat and potentially seize.

Regular oil changes can also help improve your car's fuel efficiency and save you money in the long run. Old, dirty oil can cause your engine to become less efficient, leading to decreased gas mileage and more frequent trips to the pump.
