How do I increase fuel efficiency in my Ford Fiesta?

I recently bought a Ford Fiesta and I've noticed that my fuel costs are higher than I expected. Are there any ways to improve the fuel efficiency in my car?

One of the best ways to improve fuel efficiency in your Ford Fiesta is by checking your tire pressure regularly. Under-inflated tires can decrease your fuel efficiency by up to 3%. Make sure to keep your tires inflated to the recommended pressure.

Another way to improve fuel efficiency is by avoiding excessive idling. If you're going to be stopped for more than 30 seconds, it's better to turn off your engine and restart it when you're ready to go. This can save a significant amount of fuel over time.

Consider using a fuel additive to clean your fuel injectors and improve your car's overall performance. This can help increase fuel efficiency and reduce emissions.
