How to properly maintain your Ford Mondeo's engine?

I have recently purchased a Ford Mondeo and I'm wondering what steps I should take to ensure the longevity and optimal performance of its engine?

Regularly check your engine's oil and coolant levels to avoid any potential damage or overheating issues.

Change your engine's air filter every 12,000 miles or as recommended in your car's manual. This will improve air flow and protect your engine from debris.

Use high-quality fuel and follow manufacturer's recommendations on fuel type and octane rating to optimize engine performance.
