What is the best way to maintain the fuel efficiency of my Ford Focus?

I recently purchased a Ford Focus and I want to make sure I am taking proper care of it to maintain its fuel efficiency. Any tips or advice for keeping my Ford Focus running smoothly and efficiently?

Regularly check and change your air filter to ensure proper air flow and fuel combustion. This will not only improve fuel efficiency, but also extend the life of your engine.

Make sure you follow the recommended maintenance schedule for your Ford Focus. This includes regular oil changes and tire rotations to keep your car running at its best.

Avoid excessive idling and try to combine errands to reduce the number of short trips you take in your Ford Focus. Short trips can decrease fuel efficiency and increase wear and tear on your engine.
