How can I optimize my Ford Focus's fuel economy?

I recently bought a Ford Focus and I'm looking to improve its fuel efficiency. What are some tips or modifications that I can make to get the most out of every gallon of gas?

Consider changing your driving habits, such as accelerating smoothly and avoiding rapid braking. This can have a significant impact on your car's fuel efficiency.

Regularly maintain your car by keeping up with oil changes, tire pressure checks, and air filter replacements. This can help improve your fuel economy and extend the life of your car.

Upgrade to high-quality, low rolling resistance tires for improved fuel efficiency. These tires are designed to decrease the amount of energy needed to move your car and can result in better gas mileage.
