What oil does my car take?
Guide · Basics
The exact oil your car takes is set by the manufacturer for your specific year, make, model and engine, and it appears in your owner's manual (and often on the oil filler cap). You need two things: the viscosity grade (e.g. 0W-20) and the required specification (e.g. API SP or dexos1 Gen3).
Checklist
Manual-first oil check
- Find the exact oil section in the owner’s manual, not only a forum or retailer result.
- Write down the viscosity grade and the required specification as two separate requirements.
- Confirm engine, model year, market, and service schedule before buying oil or parts.
- Check capacity with filter and avoid overfilling.
- Keep a mileage/date note after the service so the next interval is clear.
Use this before buying oil, choosing an alternate grade, or changing the interval.
The two things you need
“What oil does my car take?” has two parts, and you need both:
- Viscosity grade — the number like 0W-20 or 5W-30 (how the oil flows cold and hot).
- Specification — the standard the oil must meet, like API SP, ILSAC GF-6A, or an OEM approval such as dexos1 Gen3. The grade alone is not enough — see why on our oil viscosity chart and in API SP vs ILSAC GF-6.
Where to find it
- Owner’s manual — the authoritative source. Look in the maintenance/specifications section for the grade, specification, and the oil capacity (how many quarts).
- Oil filler cap — often shows the viscosity grade (e.g. “0W-20”), a quick confirmation.
Find the manual before choosing oil
Start with the official owner-manual finder guide. Match the model year, engine and market, then record the viscosity grade and exact specification or approval. Keep the manual edition and page with your notes using the manual evidence builder.
Our car oil lookup is a limited provisional catalog, not a verified fitment database. Its sample or pending-review records do not establish which oil to buy. If your exact vehicle is missing, use the manufacturer’s manual rather than a nearby model or engine.
Once you have the requirements, compare the manual with the bottle. An unknown or partial result needs further evidence; it is not approval to substitute oil.
Frequently asked questions
Where is the oil type listed on my car?
Use the maintenance or specifications section of the exact owner's manual. An oil-cap marking is a clue to confirm against the manual; it may not show the full specification or capacity.
Is the oil on the cap enough?
The cap usually shows the viscosity grade, but not always the full specification or the capacity. Confirm the grade, spec, and oil capacity in your manual.
Does the same model always take the same oil?
No — different engines, model years, and markets can call for different oil. Always match your exact engine, which is why our lookup asks for it.
