Does oil capacity vary by engine on a 2020 Kia Optima?

Does maintenance data change by model year on a Kia Optima?
Yes. This page keeps one model URL and loads the stored specifications for the year you select. The default year is the latest catalog year that has maintenance specifications.
How do I match engine oil for a 2020 Kia Optima?
Select the engine, because capacity and grade are stored separately. A catalog oil product is shown when it is mapped to this model year and its title contains that engine's stored viscosity. Manufacturer oil-approval specifications are not stored, so a title match is not an approval.
What is the maintenance interval for a Kia Optima?
This catalog does not store a manufacturer maintenance interval for the Kia Optima. Confirm service timing in the owner's manual or the vehicle maintenance monitor. Capacities and sizes on this page are not a mileage schedule.
What should I verify before buying parts for a Kia Optima?
Match the model year and, when the catalog lists more than one engine, the engine. Oil grade, battery group, and wiper position are separate values. A catalog product mapped to the vehicle is not a claim that every engine uses that product.
