How to increase fuel efficiency on my Kia Soul?

I've noticed that my Kia Soul isn't getting the best gas mileage. Are there any specific steps I can take to increase its fuel efficiency?

One way to increase fuel efficiency is by keeping your tires properly inflated. Under-inflated tires can cause your car to use more gas than necessary.

Regularly changing your air filter can also help improve fuel efficiency. A dirty air filter can reduce the amount of air flow to your engine, making it work harder and use more gas.

Another tip is to avoid idling for long periods of time. If you're waiting for someone or stuck in traffic, consider turning off your engine to conserve fuel.

Lastly, try to limit the amount of weight in your car. Extra weight can cause your car to use more gas, so try to only carry essential items.
