Hyundai Tucson Oil Capacity & Oil Type
TL;DR
Tucson oil capacity with filter ranges from about 4.2 to 5.8 US quarts (4.0-5.5 L) depending on engine; Hyundai specifies 0W-20 full synthetic for most gasoline engines built since around 2017.
Hyundai Tucson Engine Oil Capacity by Generation
The Hyundai Tucson has been built with several different engine families since it launched, and oil capacity changes with the engine - not simply with the model year. Before adding oil, confirm your exact engine using the information below.
Where to confirm the exact figures for your own vehicle
The number that matters most is the one for your specific car. Check these authoritative sources first.
- The oil specification sticker under the hood, near the oil filler cap
- Your owner's manual (glovebox copy or Hyundai's online manual portal), under Maintenance / Recommended Fluids
- The driver's door jamb placard, which often lists tire and sometimes fluid data
- A Hyundai dealer parts or service advisor, who can pull the exact figure from your VIN
Capacity and viscosity by engine
| Engine code / years | Capacity with filter (L / US qt) | Viscosity |
|---|---|---|
| 2.0L Nu MPI (2016-2020, 3rd gen) | 4.0 L / 4.2 US qt | 5W-20 or 5W-30 full synthetic |
| 2.4L Theta II GDI (2016-2020, 3rd gen) | 4.5-4.8 L / 4.8-5.1 US qt (sources vary) | 0W-20 full synthetic |
| 1.6L Turbo GDI - Smartstream (2019-2025, incl. Hybrid) | 4.8 L / 5.1 US qt | 0W-20 full synthetic |
| 2.5L Smartstream G4KH (2022-2026, 4th gen) | 4.8-5.5 L / 5.1-5.8 US qt (sources vary) | 0W-20 full synthetic |
Why the figures vary
Even within one engine family, published capacities sometimes differ by a few tenths of a quart between service sources. This can reflect rounding, dry-fill versus service-fill amounts, or differing regional spec sheets. When two reliable sources disagree we show both figures as a range rather than guessing a single number.
Diesel and older generations
The Tucson diesel (2.0L CRDi, sold mainly outside North America) and the first- and second-generation gasoline engines are not listed above because the published figures for them conflicted too widely to state with confidence. If you drive one of these, check your owner's manual or oil filler cap for the correct number rather than relying on an online estimate.
Summary
| 2.0L Nu MPI (2016-2020) | 4.0 L / 4.2 US qt - 5W-20 or 5W-30 |
|---|---|
| 2.4L Theta II GDI (2016-2020) | 4.5-4.8 L / 4.8-5.1 US qt - 0W-20 (sources vary) |
| 1.6L Turbo GDI (2019-2025) | 4.8 L / 5.1 US qt - 0W-20 |
| 2.5L Smartstream (2022-2026) | 4.8-5.5 L / 5.1-5.8 US qt - 0W-20 (sources vary) |
| Diesel & pre-2016 engines | Not confirmed here - check owner's manual |

Frequently asked questions
How much oil does a Hyundai Tucson need?
It depends entirely on the engine - from about 4.2 US qt (4.0 L) in the older 2.0L Nu engine up to about 5.8 US qt (5.5 L) in some figures for the current 2.5L Smartstream engine. Check the table above for your specific engine and confirm with your oil filler cap or owner's manual before an oil change.
What oil viscosity does Hyundai recommend for the Tucson?
Most Tucson gasoline engines built since around 2017 (2.4L Theta II, 1.6L Turbo GDI, 2.5L Smartstream) call for 0W-20 full synthetic oil; the older 2.0L Nu engine accepts 5W-20 or 5W-30. Using a viscosity outside Hyundai's specification can affect engine performance and warranty coverage, so check your filler cap or manual if you are unsure.
Does the oil capacity figure include the oil filter?
Yes, the figures in the table above are the total fill volume with a new oil filter installed, which is the number a technician uses for a routine oil change. The dry-fill capacity (a completely empty engine with no filter) is slightly lower and rarely relevant for a standard service.
Why do different websites list different oil capacities for the same Tucson?
Parts retailers and oil-lookup sites sometimes pull from different regional service databases, round numbers differently, or mix up dry-fill and service-fill figures. When sources disagree we list a range instead of picking one number - the safest confirmation is always your own owner's manual or the sticker near the oil filler cap.
