Hyundai i30 Engine Oil — Grade, Capacity & Recommendations (2017-2024)
Oil Specification by Engine
| Engine | Oil grade | Specification | Capacity (inc. filter) |
|---|---|---|---|
| 1.0 / 1.5 T-GDi (petrol) | 0W-20 | API SN PLUS/SP | ~3.9 L |
| 1.6 CRDi (diesel) | 5W-30 | ACEA C3 | ~5.7 L |
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
Diesel — 5W-30, ACEA C2/C3
Castrol EDGE 5W-30 (ACEA C3)
Full-synthetic 5W-30 (ACEA C2/C3) for the 1.6 CRDi diesel.
Shell Helix Ultra ECT C3 5W-30
Low-SAPS 5W-30 (ACEA C2/C3) for the diesel, DPF-safe.
Any 5W-30 meeting ACEA C3 / API SP
For the turbo T-GDi petrol — any 0W-20 meeting API SN PLUS / SP. The diesel uses 5W-30 (ACEA C2/C3).
Which Oil Does Your Hyundai i30 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 CRDi diesel uses 5W-30 (ACEA C2/C3), a low-SAPS oil that protects the particulate filter. 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 i30 take?
The turbo T-GDi petrol uses 0W-20 (API SN PLUS/SP), and the CRDi diesel uses 5W-30 (ACEA C2/C3) — all to API SP / ILSAC GF-6. Check your filler cap.
Why does my i30 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 i30?
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 →
