How to maintain my Ford Fiesta's engine for better performance?

I own a Ford Fiesta and I've noticed a decrease in its performance lately. I want to make sure I'm properly maintaining the engine to keep it running smoothly. What steps should I take to ensure my Ford Fiesta's engine is in top condition?

Regularly check and change your engine oil according to the manufacturer's recommended schedule. This will help keep your engine clean and functioning properly.

Keep an eye on your coolant levels and make sure to top it off when needed. Low coolant levels can cause your engine to overheat and potentially lead to expensive damage.
