The 2005 Kia Optima comes in two different trims. One has a 2.4 L inline 4 engine that requires about 4.5 quarts of 5W-20 synthetic oil. The other trim features a 2.7 L V6 engine that also uses 5W-20 synthetic oil. If you can't find 5W-20 oil, you can temporarily use 5W-30 oil but it is advisable to switch back to 5W-20 during your next oil change for optimal performance. Both types of oil are suitable for regular use. It is recommended to change the oil every 7,500 to 10,000 miles for best results. If you prefer to do your own oil changes, you can purchase the necessary oil from retailers like Autozone or Walmart.

    The 2005 Kia Optima offers a choice between two engine options. The standard engine is a 2.4L inline-4, requiring 4.5 quarts of either 5W20 or 5W30 synthetic oil. The alternative engine, a 2.7L V6, needs 5.1 quarts of the same synthetic oil options. Kia approves the use of either oil weight for both engines.
