Oil capacity for a 2016 Kia Optima varies by engine: about 4.7 quarts with a filter for the 2.4L engine, and about 5.1 quarts with a filter for the 2.0L turbo.
The exact amount you should add depends on your engine variant and whether you’re replacing the oil filter. This article explains the capacities for the two main engines offered in the 2016 Optima and provides guidance on how to fill, check, and verify the oil level safely.
Oil capacity by engine type
Below are the typical oil capacities for the two engine configurations found in the 2016 Optima. They assume a standard oil change with a new filter and that the engine is at normal operating temperature when the level is checked.
- 2.4-liter GDI I4: 4.7 quarts (with filter)
- 2.0-liter turbocharged I4: 5.1 quarts (with filter)
Note: Actual capacity can vary slightly by VIN, oil filter type, and regional specifications. After pouring in the oil, use the dipstick to confirm the full level on the marks.
Recommended oil types and checking procedure
Viscosity recommendations depend on the engine variant and climate. For most Optimas, the following viscosities are commonly recommended, but always verify with your owner's manual or a Kia dealer for your specific VIN and regional requirements.
- 2.4-liter engine: 5W-20
- 2.0-liter turbo engine: 5W-30
Before you start pouring, have a clean, drain-free container ready and a fresh oil filter. After an oil change, follow these steps to check and correct the level.
- Park on level ground and set the parking brake. Turn off the engine and wait 5–10 minutes for oil to settle.
- Open the hood and locate the oil dipstick. Wipe it clean with a rag.
- Reinsert the dipstick fully, then pull it out again to read the oil level.
- If the level is below the ADD or MIN mark, add oil in small increments (about a quarter to a half-quart) and recheck after each addition.
- Continue until the dipstick shows the level at the full mark. Do not overfill, as overfilling can cause engine damage.
After adding oil, if you’re near the full mark but still low, run the engine for a minute or two and recheck the level with the dipstick once it’s cooled slightly.
Important notes
Always confirm the exact specification for your vehicle using the owner’s manual or a Kia dealership, as oil capacity and viscosity can vary by production date, regional requirements, and VIN. If you recently replaced the oil filter, you may need the higher end of the capacity to ensure a full proper fill.
Summary
For a 2016 Kia Optima, plan on about 4.7 quarts of oil for the 2.4L engine and about 5.1 quarts for the 2.0L turbo, both with a new filter. Use 5W-20 for the 2.4L and 5W-30 for the 2.0L turbo, and always verify with the owner’s manual for your specific vehicle. After changing the oil, check the level with the dipstick and top up gradually to the full mark, avoiding overfill. Regular maintenance and correct oil specifications help keep the Optima running smoothly.
