How to improve fuel efficiency of my Kia Sorento?

I have been noticing that my Kia Sorento's fuel efficiency has been decreasing. What are some tips or techniques I can use to improve it?

Regularly check and change your car's air filter. A dirty air filter can reduce fuel efficiency by up to 10%.

Maintain proper tire pressure. Under-inflated or over-inflated tires can decrease fuel efficiency.

Avoid aggressive driving, such as excessive speeding and rapid acceleration. This can greatly impact fuel efficiency.
