Kia Sorento Oil Capacity & Oil Type
TL;DR
Kia Sorento oil capacity ranges from about 4.4 L on the original 3.5L V6 up to 6.5 L on later 3.3L V6 and 2.5L engines - check your engine code and model year before topping off.
Why there is no single answer for the Sorento
The Kia Sorento has been built across four generations since 2002, with engine families ranging from a 3.5L Sigma V6 to the current 2.5L Smartstream four-cylinder (naturally aspirated and turbocharged). Oil capacity with a new filter changes noticeably between these engines, and even within the same displacement, revisions between model years have shifted the figure. Always confirm the engine code stamped on the block or listed on your emissions/VIN sticker before assuming a capacity.
Verified capacities by engine
The table below lists only the figures that were corroborated by workshop and parts-industry sources for that specific engine code and year range. Where sources gave slightly different numbers for adjacent model years of the same engine, both are shown.
| Engine code / years | Capacity with filter (L / US qt) | Viscosity |
|---|---|---|
| 3.5L Sigma V6 - 2003-2006 | 4.4 L / 4.6 qt | 10W-30 (API SH/SJ) |
| 2.4L Theta II I4 - 2011-2012 | 4.6 L / 4.9 qt | 5W-20 |
| 2.4L Theta II GDI I4 - 2013-2015 | 5.0 L / 5.3 qt | 5W-20 |
| 3.3L Lambda II V6 (GDI) - 2016-2018 | 5.7 L / 6.0 qt | 5W-30 |
| 3.3L Lambda II V6 (GDI) - 2019-2020 | 6.5 L / 6.9 qt | 5W-30 |
| 2.5L Smartstream I4 (naturally aspirated) - 2021-2024 | 5.8 L / 6.1 qt | 0W-20 |
| 2.5L Smartstream Turbo I4 (G4KP) - 2021-2024 | 5.8 L / 6.1 qt | 0W-30 |
Where to get the number for your exact car
Because trims, markets and mid-cycle revisions can shift these figures by a few tenths of a litre, treat the table as a starting reference, not a substitute for your own vehicle's documentation. The authoritative source is always:
- Your owner's manual maintenance/specifications section
- The oil specification sticker under the hood or on the oil filler cap
- The driver's door jamb placard (sometimes lists fluid specs alongside tire pressure)
- Your dealer's service department, who can look up the exact figure from your VIN
A note on diesel and hybrid variants
Sorento diesel engines sold outside North America (2.0L and 2.2L CRDi) and the 1.6L turbo hybrid/PHEV powertrain use different capacities and viscosities again (commonly quoted around 6.3-6.7 L for the diesels and near 4.8 L for the hybrid four-cylinder), but because fewer independent sources were available to cross-check those figures precisely, we recommend confirming them directly from your owner's manual rather than relying on a web figure.

Frequently asked questions
Is Kia Sorento oil capacity the same for every model year?
No. It changes by generation and by engine code - for example the 3.3L V6 sold from 2016-2018 takes about 5.7 L with filter, while the same-displacement engine in 2019-2020 models takes closer to 6.5 L. Always check your specific engine code, not just the displacement.
How do I find my Kia Sorento's engine code?
It is stamped on the engine block (usually near the front) and is also listed on the emissions label under the hood. Your owner's manual and any dealer parts lookup will also identify it from your VIN.
Does the 2.5L turbo and non-turbo Sorento take the same amount of oil?
Sources indicate both the 2.5L naturally aspirated and 2.5L turbo (G4KP) Smartstream engines take about 5.8 L (6.1 US quarts) with a filter change, but they require different viscosity - 0W-20 for the naturally aspirated version and 0W-30 for the turbo.
What if I cannot find my exact engine's capacity here?
Do not guess. Check the oil filler cap, the owner's manual specifications page, or ask your dealer's service department to pull the figure from your VIN - overfilling or underfilling by guesswork can damage the engine.
