Oil Specification by Engine
| Engine | Oil grade | Specification | Capacity (inc. filter) |
|---|---|---|---|
| 1.2 Dualjet (petrol, mild hybrid) | 0W-20 | API SP / ACEA C2 | ~3.6 L |
| 1.4 BoosterJet (Swift Sport) | 5W-30 | ACEA C3 | check handbook |
Suzuki has no proprietary approval list — any oil showing the correct API rating and viscosity is acceptable. Capacities are small, so the oil works hard; 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
Dualjet / hybrid — 0W-20, API SP
Any 0W-20 meeting API SP
For the Dualjet/hybrid engines, use a 0W-20 carrying API SP (e.g. Suzuki Genuine 0W-20).
BoosterJet turbo — 5W-30, ACEA C3
Any 5W-30 meeting ACEA C3
The 1.4 BoosterJet turbo uses a 5W-30 (ACEA C3) — e.g. Castrol EDGE 5W-30 C3.
Which Oil Does Your Suzuki Swift Need?
Suzuki specifies oil by viscosity and API rating, not a proprietary code. The Dualjet port-injection engines and SHVS mild-hybrid units use a thin 0W-20 (API SP) for economy. The turbocharged 1.4 BoosterJet runs higher pressures and uses a 5W-30 (ACEA C3). Always use a synthetic API SP oil and change it on time — the small sumps mean the oil degrades faster than in larger engines.
Oil Change Intervals
Suzuki uses fixed intervals: typically 10,000 miles (15,000 km) or 12 months for normal use, 5,000 miles for severe/off-road use. There is no oil-life monitor.
Tip: the small oil capacity means the oil works hard — don’t extend intervals, and fit a new filter with the oil.
Frequently Asked Questions
What engine oil does the Suzuki Swift take?
The Dualjet and mild-hybrid engines use 0W-20 (API SP); the 1.4 BoosterJet turbo uses 5W-30 (ACEA C3). Check your oil filler cap.
Does Suzuki need a special approved oil?
No — Suzuki uses API standards rather than a proprietary approval. Any synthetic oil showing the correct API rating (SP) and viscosity is suitable.
Why such frequent oil changes on a Suzuki?
The engines have small oil capacities, so the oil works harder and degrades faster — especially in short-trip or off-road use. Stick to the fixed intervals.
How much oil does it take?
Around 3.3–3.9 litres including a filter change, depending on engine; confirm in your handbook.
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 →
