What is the most efficient way to increase fuel efficiency in a Kia Soul?

I often find myself spending too much on gas when driving my Kia Soul. Are there any specific methods or adjustments that I can make to improve its fuel efficiency?

Regularly maintaining and replacing the air filter is a simple and effective way to improve fuel efficiency. Additionally, practicing smooth and steady driving habits can also help reduce fuel consumption.

Installing a cold air intake system and upgrading to higher quality spark plugs can also contribute to better fuel efficiency. Make sure to do your research and choose reputable brands for these modifications.

In addition to mechanical improvements, changing your driving style can also greatly impact fuel efficiency. Avoid aggressive acceleration and braking and consider using cruise control for highway driving.
