How to increase the fuel efficiency of my Ford Focus?

I've been driving my Ford Focus for a while now and I'm noticing that my fuel costs are adding up. Is there anything I can do to improve the fuel efficiency of my car?

Regularly maintaining your car, such as changing the air filter and spark plugs, can improve fuel efficiency. Also, try to avoid idling for too long and drive at a steady speed rather than accelerating and braking frequently.

Make sure to check your tire pressure regularly. Underinflated tires can decrease fuel efficiency. Also, using the recommended grade of gasoline for your car can make a difference.

Consider carpooling or using public transportation for shorter trips to reduce the amount of driving you do. This can save you money on gas and also help reduce your carbon footprint.
