Hyundai Elantra Oil Capacity & Oil Type
TL;DR
Elantra oil capacity with filter runs from about 3.8 L to 4.8 L depending on engine (1.8L, 2.0L, or 1.6L turbo); viscosity is typically 5W-20 or 0W-20, with turbo N models spec'd for 5W-30.
Why there is not one answer for Elantra
The Elantra name has covered several unrelated engine families since 2011, and each one has its own oil fill amount. Mixing up a fifth-generation 1.8L figure with a modern Smartstream 2.0L figure - or a turbo engine with a naturally aspirated one - is a common and avoidable mistake. Always confirm which engine is under your hood before topping off or doing a full fill after a filter change.
Capacity and viscosity by engine
The table below lists the figures we were able to confirm from service references. Where sources disagreed slightly, we show the range rather than a single invented number.
| Engine / years | Capacity with filter (L / US qt) | Viscosity |
|---|---|---|
| 1.8L Nu MPI - 5th gen (2011-2016) | 4.0-4.3 L (4.2-4.5 qt) - sources vary | 5W-20 (5W-30 acceptable in some markets) |
| 2.0L Nu MPI - 6th gen (2017-2020) | 3.8 L (4.0 qt) | 5W-20 |
| 2.0L Smartstream MPI - 7th gen non-hybrid (2021-2024) | 4.0 L (4.2 qt) | 0W-20 |
| 1.6L Turbo GDI - Sport / N Line / Elantra N | 4.8 L (5.1 qt) | 5W-30 (check the N owner's manual, some calibrations list 0W-20) |
Where to get the number for your exact car
Because trim and market can shift these figures slightly, treat the table as a starting point, not a substitute for your own vehicle's data:
- The engine oil specification sticker under the hood, near the filler cap
- Your owner's manual, in the maintenance or capacities section
- The driver's door jamb placard (mainly for tire and load info, but often references the manual section for fluids)
- A dealer parts/service lookup using your VIN, which pins down the exact engine build
A note on quarts versus liters
US quarts and liters are not interchangeable 1:1 - 1 US quart equals 0.946 liters. Any spec sheet that lists the same number for both units has made an error, so double-check before you buy oil by the container.
Summary
| 1.8L Nu MPI (2011-2016) | 4.0-4.3 L / 4.2-4.5 qt, 5W-20 |
|---|---|
| 2.0L Nu MPI (2017-2020) | 3.8 L / 4.0 qt, 5W-20 |
| 2.0L Smartstream (2021-2024) | 4.0 L / 4.2 qt, 0W-20 |
| 1.6L Turbo GDI (Sport/N Line/N) | 4.8 L / 5.1 qt, 5W-30 |
| Unit conversion | 1 US qt = 0.946 L |
| Best source for your car | Oil cap label, owner's manual, or VIN lookup |

Frequently asked questions
Does every Hyundai Elantra take the same amount of oil?
No. Oil capacity depends on which engine is fitted, not just the model name. The 2.0L Nu, 2.0L Smartstream, and 1.6L turbo engines used across different Elantra generations each have their own fill amount, ranging from roughly 3.8 L to 4.8 L with a new filter.
What weight of oil does a 2021-2024 Elantra 2.0L need?
The 2021-2024 non-hybrid Elantra with the Smartstream 2.0L engine is specified for 0W-20 full synthetic oil, with a fill of about 4.0 L (4.2 US qt) when the filter is also replaced. Confirm against your own oil cap or manual since running changes can occur.
Is the turbo Elantra (N Line or N) oil capacity different from the regular 2.0L?
Yes. The 1.6L turbocharged engine used in Sport, N Line, and Elantra N models holds noticeably more oil, around 4.8 L (5.1 US qt) with filter, and many versions call for 5W-30 rather than the 0W-20 used in the base 2.0L engine.
Where is the definitive oil capacity for my specific Elantra?
The most reliable sources are the label under the hood near the oil filler cap, the capacities table in your owner's manual, or a dealer parts lookup by VIN. These reflect the exact engine and market calibration of your car rather than a general model average.
