How do I properly maintain my Kia Soul's engine?

I've noticed that my Kia Soul's engine seems to be lagging and not performing as well as it used to. What steps should I take to ensure proper maintenance for my engine?

Regular oil changes and using high quality oil can greatly improve your engine's performance. Also, be sure to check and replace your air filter regularly as a clogged filter can bog down your engine.

Don't forget to regularly check and top off all of your fluids, including coolant, transmission fluid, and brake fluid. Neglecting these fluids can lead to major engine problems.

Consider using fuel additives or cleaning agents to remove harmful build-up in your engine. This can help improve performance and extend the life of your engine.
