★ Top Answer
The 2015 Kia Optima requires either 5W-20 or 5W-30 oil. It is important to change the oil as needed, typically every 5,000 to 10,000 miles. Neglecting to do so can lead to engine problems. Using high-quality oil is crucial for optimal engine performance, as issues with the oil can arise over time. One common indicator of problems is a foul burning odor, which should be addressed promptly to prevent potential engine damage. Poor-quality oil can result in engine failure, decreased fuel efficiency, and the occurrence of an unusual knocking sound coming from the engine.
