2019 Kia Optima 2.4 Oil Capacity
2019 Kia Optima 2.4 Oil Capacity: 5.07 US qt with filter, application boundaries, refill procedure, dipstick check and official manual lookup.
Kia lists 4.8 L (5.07 US qt) for a drain and refill on the 2019 Optima 2.4L GDI.
Kia lists 4.8 L (5.07 US qt) for a drain and refill on the 2019 Optima 2.4L GDI. That number is a refill starting point for the identified engine, not permission to pour the entire amount without checking. Oil can remain in galleries, coolers, a tilted pan, or an old filter, and aftermarket pans can change total volume. The safest method is to verify the engine code and model year, use the correct viscosity and approval, refill slightly below capacity, circulate the oil, wait, and finish by the dipstick.
This guide separates similarly named engines and model generations because capacity errors commonly come from a search result that omits the year or engine code. The table also distinguishes “with filter” from “without filter.” During a normal oil change, replace the filter and use the with-filter figure, then confirm the final level on level ground under the conditions specified by the owner manual.

2019 Kia Optima 2.4 Oil Capacity
| APPLICATION / ITEM | SPECIFICATION | NOTES |
|---|---|---|
| Oil and filter change | 5.07 US qt | 4.8 L; drain and refill |
| Final level | Verify after drain-back | Level ground and correct procedure |
Use the oil classification and viscosity chart from the same model-year manual; capacity by itself is not a complete oil specification. Refill below 4.8 L initially, run the engine while checking the new filter and drain plug, shut down on level ground, allow drain-back and finish at the dipstick without exceeding the full mark.
Oil-capacity chart for 2019 Optima 2.4L
Use the chart as an application lookup. Applies to U.S.-market 2019 Optima LX and S models with the 2.4L GDI. The 1.6L turbo, 2.0L turbo and hybrid powertrains use different refill data and should be identified separately. A capacity printed beside the wrong engine code is not “close enough”; even engines sharing the same displacement can have different pans, filters, coolers, or drain-back behavior. If the vehicle has been swapped, rebuilt, or fitted with an aftermarket pan, use the installed hardware manufacturer's capacity and calibration marks.
The most common current application begins near 5.07 US qt. Begin below that amount and finish by measurement. The difference between the add and full marks is often about one quart, but do not assume that relationship when the dipstick is aftermarket, damaged, or paired with a non-original tube. Investigate a reading that remains absent or implausibly high.

Common causes of a capacity mismatch
Use the oil classification and viscosity chart from the same model-year manual; capacity by itself is not a complete oil specification. Refill below 4.8 L initially, run the engine while checking the new filter and drain plug, shut down on level ground, allow drain-back and finish at the dipstick without exceeding the full mark. If the verified dipstick result and the expected quantity disagree materially, stop and identify the cause instead of choosing whichever number is more convenient.
- The lookup used the model name but not the model year or engine code.
- The quoted figure excluded the filter while the filter was replaced.
- The vehicle was not level or the oil had not drained back before checking.
- An oil cooler, remote filter, aftermarket pan, engine swap, or incorrect dipstick changed the system.
- The old filter gasket remained on the housing or a leak began after startup.
- The crankcase was filled to the advertised capacity without a final dipstick check.
