How to improve the fuel efficiency of the Ford Focus?

I have been driving my Ford Focus for a few years now and I noticed that my fuel consumption has been increasing. What are some ways that I can improve the fuel efficiency of my car without sacrificing performance?

One of the best ways to improve the fuel efficiency of your Ford Focus is to regularly maintain your car. This includes changing the oil and air filter, keeping your tires properly inflated, and getting a tune-up when needed.

Another tip is to avoid idling your car for long periods of time. If you are waiting in your car for more than a minute, turn off the engine to save fuel. Also, try to avoid heavy acceleration and braking as it can increase fuel consumption.
