What is the best way to improve fuel efficiency in a Ford Focus?

I have a Ford Focus and I am looking for ways to improve its fuel efficiency. What are some tips or modifications I can make to my car to save on gas?

Most importantly, make sure to properly inflate your tires. This can greatly improve fuel efficiency. You can also consider using a fuel additive to clean your engine and improve mileage. Another option is to upgrade to a high-flow catalytic converter.

Avoid excessive idling and aggressive driving. These habits can significantly decrease your fuel efficiency. Additionally, regularly changing your air filter can also help.

Invest in a hybrid or electric model of the Ford Focus. These cars are specifically designed to be more fuel efficient and environmentally friendly.
