How do I increase fuel efficiency in my Ford Focus?

I recently bought a Ford Focus and noticed that it consumes a lot of fuel. Any tips on how to improve its fuel efficiency?

One way to increase fuel efficiency in your Ford Focus is to make sure your tires are properly inflated. Underinflated tires can decrease gas mileage. Also, try to avoid heavy acceleration and braking, as it can use up more fuel.

Regular maintenance and tune-ups can also improve the fuel efficiency of your Ford Focus. Make sure to follow the recommended service schedule and check for any engine or fuel system issues.

Consider using a fuel additive or switching to a higher quality gasoline, as it can improve the performance of the engine and increase fuel efficiency. However, be sure to consult your owner's manual before making any changes.
