How to improve fuel efficiency on my Ford Focus?

I have a Ford Focus and I noticed that the fuel consumption is higher than I expected. What steps can I take to improve the fuel efficiency of my car?

One way to improve fuel efficiency is by properly maintaining your car. Make sure to regularly change the oil and air filter. This can greatly improve the performance of your car and also save on fuel consumption.

Another tip is to drive at a constant speed and avoid sudden accelerations and braking. This not only improves fuel efficiency but also reduces wear and tear on your car's engine.

Consider using a fuel additive or cleaner to keep your engine running smoothly and efficiently. This can also help to reduce emissions and improve overall performance.

Another helpful tip is to avoid carrying excess weight in your car. The heavier your car, the more fuel it will consume. Remove unnecessary items from your trunk and keep the car as light as possible.
