The 2016-2020 Kia Optima requires regular maintenance to ensure optimal performance. Oil changes are recommended every 7,500 miles or 12 months using 5W-20 or 5W-30 synthetic oil. Tire rotations should be performed every 7,500 miles, and brake inspections are advised every 15,000 miles. Air filters and cabin filters should be replaced every 30,000 miles.

To replace the cabin air filter in a 2016-2020 Kia Optima, open the glove compartment and remove the contents. Locate the glove compartment stopper and detach it. Press the sides of the glove compartment inward to release it from its hinges. Behind the glove compartment, you'll find the cabin air filter housing. Open the housing cover, remove the old filter, and insert the new one, ensuring the airflow arrow points downward. Reassemble the glove compartment and stopper.

The check engine light in your 2016-2020 Kia Optima can indicate various issues, such as a loose gas cap, faulty oxygen sensor, or catalytic converter problems. Start by checking the gas cap to ensure it’s tight. If the light remains on, use an OBD-II scanner to retrieve the error code. Common codes include P0420 (catalytic converter efficiency) and P0171 (system too lean). Address the specific issue or consult a certified technician for further diagnosis and repair.

To optimize the performance of your 2016-2020 Kia Optima, ensure regular maintenance, including oil changes, air filter replacements, and tire rotations. Use high-quality fuel and consider upgrading to performance tires for better grip. For turbocharged models, allow the engine to cool before turning it off to prevent turbocharger damage. Additionally, avoid excessive idling and maintain proper tire pressure. For enhanced handling, consider installing aftermarket suspension components or upgrading the exhaust system.
