How can I improve fuel efficiency on my Kia Soul?

I just got a Kia Soul and I'm looking for ways to improve its fuel efficiency. Any tips or recommendations?

Regular maintenance is key in improving fuel efficiency. Make sure to keep your tire pressure at the recommended levels and change the air filter regularly.

Avoid unnecessary idling and use cruise control on the highway. This can help decrease fuel consumption.

Consider using a fuel additive or switching to premium gas. It may cost more upfront, but it can increase your overall fuel efficiency.
