Hyundai i20 Engine Oil — Grade, Capacity & Recommendations (2020-2024)
Oil Specification by Engine
| Engine | Oil grade | Specification | Capacity (inc. filter) |
|---|---|---|---|
| 1.0 T-GDi (petrol) | 0W-20 | API SN PLUS/SP | ~3.9 L |
| 1.2 MPI (petrol) | 5W-30 | ACEA A5 | check handbook |
Hyundai specifies oil by viscosity and API/ACEA class (no proprietary code). All modern engines need API SP / ILSAC GF-6. Capacities vary by engine — confirm by VIN.
Not sure which engine you have? The required grade is on the oil filler cap; the engine code is in section D.2 of your V5C.
Recommended Engine Oils
Recommended oils by engine
Castrol EDGE 5W-30 (ACEA A5)
For the 1.2 MPI petrol — full-synthetic 5W-30 meeting ACEA A5 / API SP.
Shell Helix Ultra ECT C3 5W-30
For the 1.2 MPI petrol — a full-synthetic 5W-30 meeting ACEA A5.
Any 5W-30 meeting ACEA A5 / API SP
For the 1.0 T-GDi turbo — any 0W-20 meeting API SN PLUS / SP. The 1.2 MPI petrol uses 5W-30 (ACEA A5).
MPI petrol — 5W-30, ACEA A5
MPI petrol: 5W-30 ACEA A5
The naturally aspirated MPI engine uses a 5W-30 meeting ACEA A5 (e.g. Castrol Magnatec 5W-30 A5).
Which Oil Does Your Hyundai i20 Need?
Hyundai uses standard API/ACEA specifications rather than a proprietary code. The turbo T-GDi petrol uses 0W-20 to API SN PLUS/SP for efficiency and protection against low-speed pre-ignition. The naturally aspirated MPI petrol uses 5W-30 to ACEA A5. All modern engines require API SP / ILSAC GF-6.
Oil Change Intervals
Hyundai’s service interval is typically 12 months or ~10,000–12,000 miles. Note Hyundai’s 5-year warranty can be affected if the wrong oil or a missed service is recorded — keep receipts showing the correct API SP oil.
Tip: GDi and Smartstream engines can use oil between changes; check the level regularly and fit a new filter with the oil.
How to Check Your Oil Level
Step 1: Park on level ground and wait at least 5 minutes after turning off the engine.
Step 2: Remove the dipstick, wipe it clean, reinsert fully, then remove again to read the level.
Step 3: The oil level should be between the minimum and maximum marks. Top up in small amounts if needed.
Frequently Asked Questions
What engine oil does the Hyundai i20 take?
The turbo T-GDi petrol uses 0W-20 (API SN PLUS/SP), and the MPI petrol uses 5W-30 (ACEA A5) — all to API SP / ILSAC GF-6. Check your filler cap.
Why does my i20 need API SP oil?
API SP protects against low-speed pre-ignition (LSPI) on turbocharged GDi engines and improves timing-chain wear protection. Using a correctly certified oil also helps protect your warranty.
Can I use any 5W-30 in my i20?
Match the grade to your engine: 0W-20 (API SN PLUS/SP) for turbo T-GDi petrol and hybrids; 5W-30 (ACEA C2/C3) for diesels; 5W-30 (ACEA A5) for naturally-aspirated MPI petrols. A generic oil without the certification is not recommended.
How much oil does it take?
It varies by engine — confirm in your handbook; the required grade is on the oil filler cap.

How we check fitment for this guide
We cross-reference fitment figures against manufacturer specifications and OE-supplier catalogue data where available, and matched to the standard codes that actually govern fit — battery type/group sizes, wiper lengths and fitting types, bulb fitment codes, tyre size markings, and oil specifications. We work by make, model, year, engine, and build date, because a single model can take different parts across its life. Where the right part depends on your exact vehicle, we tell you to confirm by registration or VIN. More on our method →
