Kia Optima: Checking the Engine Oil Level1. Be sure the vehicle is on level ground.
2. Start the engine and allow it to reach normal operating temperature.
3. Turn the engine off and wait a few minutes for the oil to return to the oil pan.
4. Pull the dipstick out, wipe it clean, and reinsert it fully.
5. Pull the dipstick out again and check the level. The level should be between
F and L.
If the level is near or at L, add enough oil to bring the level to F. Do not overfill.

Use only the specified engine oil. (Refer to “Recommended Lubricants’’ later in this section.)
