The 2018 Kia Optima comes with a specified oil capacity of 5.1 quarts or 5 liters with a filter for the 2.4L I-4 engine, while the 1.6-liter I-4 engine has a capacity of 4.8 quarts, according to the manufacturer. Despite these noted capacities, it's important to check the oil level once you've completed the oil change. The manufacturer recommends using 5w-20 oil, suitable for all temperatures. Oil changes are suggested every 5,000 to 7,500 miles when using synthetic oil. If you opt for conventional oil, you'll need to change it more frequently as it doesn't provide the same level of engine lubrication as synthetic oil.
