How to increase the gas mileage of a Ford Focus?

I recently bought a Ford Focus and I want to improve its gas mileage. What steps can I take to achieve better fuel efficiency in my car? Any suggestions for practical and cost-effective solutions?

You can start by keeping your tires properly inflated, as under-inflated tires can decrease gas mileage. Also, avoid carrying excess weight in your car and remove any roof racks or cargo carriers when not in use. These can all contribute to reduced fuel efficiency.

Invest in a high-quality air filter and change it regularly. A clean air filter can improve gas mileage by up to 10%. Additionally, make sure to follow the recommended maintenance schedule for your car.

Consider using a fuel additive or injector cleaner to improve the performance of your engine and increase gas mileage. And don't forget to properly cap your gas tank - a loose or missing gas cap can cause fuel to evaporate and reduce efficiency.
