Hyundai Sonata Oil Capacity & Oil Type
TL;DR
Depending on generation and engine, capacity with filter runs from about 4.3 to 6.1 US quarts (4.1 to 5.8 liters); the 2.5L turbo (code C/R) needs the most, at 6.1 quarts of 0W-30.
Find your engine code first
Sonata oil capacity is set by the engine, not the model year alone, and Hyundai has used at least six four-cylinder engines across two recent generations (LF, 2015-2019, and DN8, 2020-2025). Two Sonatas from different years with the same displacement can still take different amounts of oil.
Where to confirm it for your car
The definitive source for your specific vehicle is the oil-fill cap under the hood, the dipstick markings, and the maintenance section of your owner's manual - all of which state the exact capacity and viscosity Hyundai built that engine for. The driver's door jamb placard lists tire and loading data, not oil capacity, but it is useful for confirming your trim and build date when matching an engine code. If you no longer have the manual, a dealer parts counter can look up the spec from your VIN.
Capacity and viscosity by engine
| Engine code / years | Capacity with filter (L / US qt) | Viscosity |
|---|---|---|
| 1.6L Turbo Gamma, code A (2015-2019) | 4.5 L / 4.8 qt | 5W-30 (5W-40 also listed) |
| 2.0L NA, code 1/2 (2019 base) | 4.1 L / 4.3 qt | 5W-20 |
| 2.0L Turbo Theta II, code B/6 (2015-2019) | 4.8 L / 5.1 qt | 5W-30 |
| 2.4L NA Theta II, code F/8 (2015-2019) | 4.8 L / 5.1 qt | 5W-20 |
| 2.0L NA Smartstream, code J (2020-2025) | 4.3 L / 4.5 qt | 0W-16 |
| 1.6L Turbo Smartstream, code 2/7 (2020-2023) | 4.8 L / 5.1 qt | 0W-20 |
| 2.5L NA Smartstream, code A (2020-2025) | 5.2-5.8 L / 5.5-6.1 qt (sources vary by model year) | 0W-20 |
| 2.5L Turbo Smartstream, code C/R (2021-2025) | 5.8 L / 6.1 qt | 0W-30 |
Why this varies so much
The 2020 redesign (DN8) moved the lineup to Hyundai's Smartstream engine family, which runs thinner factory-fill viscosities (0W-16 and 0W-20) than the older Theta II and Gamma engines from the LF generation (5W-20 and 5W-30). Even within the DN8 generation, published figures for the naturally aspirated 2.5L (code A) range from 5.5 to 6.1 quarts across different model years in the sources we checked, so treat that range as a starting point and confirm the exact number for your build year.
How to check safely
- Park on level ground and let the engine sit for a few minutes so oil drains back to the pan.
- Pull the dipstick, wipe it clean, reinsert fully, then pull again to read the level.
- Add oil in small amounts through the filler cap and recheck rather than pouring in a full jug.
- Match the viscosity printed on the oil cap or in the manual - using the wrong grade year-round is more likely to cause problems than being a quart off.

Frequently asked questions
How many quarts of oil does a Hyundai Sonata take with a filter change?
It depends on the engine: 2015-2019 Sonatas take 4.3 to 5.1 quarts depending on the engine code, and 2020-2025 Sonatas take 4.5 to 6.1 quarts, with the 2.5L turbo needing the most. Check your engine code against the table above or your owner's manual before buying oil.
What weight of oil does a Hyundai Sonata need?
Older Theta II and Gamma engines (2015-2019) specify 5W-20 or 5W-30. Newer Smartstream engines (2020-2025) specify thinner 0W-16, 0W-20, or 0W-30 depending on whether the engine is naturally aspirated or turbocharged. The oil-fill cap and owner's manual state the exact grade for your engine.
Where can I find the exact oil capacity for my specific Sonata?
The most reliable source is your own vehicle: check the oil filler cap, the dipstick, and the maintenance chapter of the owner's manual, all of which are set for your exact engine. A Hyundai dealer parts or service department can also pull the figure from your VIN if you no longer have the manual.
Does the turbo Sonata take more oil than the standard engine?
Generally yes for the current generation: the 2.5L turbo (code C/R, 2021-2025) takes about 6.1 quarts of 0W-30, which is at or above the naturally aspirated 2.5L figure, while the smaller 2.0L Smartstream engine takes only about 4.5 quarts of 0W-16.
