How to improve fuel efficiency in a Ford Focus?

I recently bought a Ford Focus and I've noticed that it's not as fuel efficient as advertised. How can I improve its fuel efficiency?

One way to improve fuel efficiency in your Ford Focus is to regularly maintain your car. This includes changing your air filter, spark plugs, and oil according to the recommended schedule. Also, ensure that your tires are properly inflated and that your car undergoes regular tune-ups.

Another way to improve fuel efficiency is to drive smarter. Avoid aggressive driving, unnecessary idling, and excessive speeding. Plan your trips efficiently and use cruise control when possible. These small changes can make a big difference in your fuel consumption.

Consider upgrading to more efficient tires or adding aerodynamic modifications to your car. These might cost more upfront, but they can increase your fuel efficiency in the long run.
