When you have the 1.4-liter engine in your 2016 Kia Optima, it requires 4.5 liters (4.8 quarts) of 5W-20 oil. The 2.0-liter and 2.4-liter engines both need 4.8 liters (5.1 quarts) of the same viscosity oil. The SAE 5W-20 oil is a synthetic type, which means it lasts longer compared to non-synthetic oils that typically need changing every 3,000 miles. Kia suggests changing the oil every 7,500 miles, but you might need to do it more frequently based on how you drive. The average cost for an oil change for your 2016 Optima is between $110 and $130. Labor costs around $30 to $50, so if you change the oil yourself, you can save some money. After changing the oil, remember to reset the oil life indicator.
What are the benefits of using synthetic oil?
In 2016, the recommended oil for the Kia Optima is a full synthetic SAE 5W-20 motor oil. The amount of oil needed depends on the engine size: the 1.4L engine requires 4.8 quarts, while the 2.4L and 2.0L engines need 5.1 quarts.
Due to the possibility of causing blockages or harm to VVT actuators.
Inspect your oil cap—my oil cap recommends using 5W-30.
