Mazda CX-5 Oil Capacity & Oil Type
TL;DR
Capacity ranges from 4.2 to 5.1 US quarts depending on engine (2.0L, 2.5L, or 2.5L Turbo); viscosity is 0W-20 for the naturally aspirated engines and 5W-30 for the turbo.
Mazda CX-5 oil capacity by engine
The CX-5 has been built with several different SkyActiv engines since 2013, and the oil capacity is not the same across them. Before buying oil, confirm which engine is under your hood - the code is usually printed on a sticker under the hood or listed in your registration paperwork.
Capacity and viscosity table
| Engine code / years | Capacity with filter (L / US qt) | Viscosity |
|---|---|---|
| SkyActiv-G 2.0 (PE-VPS), 2013-2016 | 4.2 L / 4.4 US qt | 0W-20 |
| SkyActiv-G 2.5 (PY-VPS), 2013-2023 | 4.5 L / 4.8 US qt | 0W-20 |
| SkyActiv-G 2.5 Turbo (PY-VPTS), 2019-2023 | 4.8 L / 5.1 US qt | 5W-30 |
| SkyActiv-D 2.2 diesel (non-US markets) | 5.1 L / 5.4 US qt | 0W-30 |
Where to confirm your exact figure
The most reliable source for your specific vehicle is not any online table - it is your own car. Check these, in order: the owner's manual glovebox booklet (Capacities section), the oil filler cap markings under the hood, and the engine code sticker near the filler cap or on the timing cover. If you tow or use severe-duty oil, also check the manufacturer towing guide for any special oil recommendations.
Why the figures differ
Mazda updated the CX-5 engine lineup twice: the original KE generation (2013-2016) offered the smaller 2.0L and the 2.5L; the KF generation (2017-2023) kept the 2.5L and later added the 2.5L Turbo (2019 onward). Each has a different sump size, so using the wrong generation figure (for example applying 2.0L numbers to a Turbo) will leave the engine under- or over-filled.
Practical tips
- Always add oil gradually and recheck the dipstick - the table capacity includes the amount lost in the old filter, so a partial drain-and-fill needs less.
- 0W-20 and 5W-30 are not interchangeable long-term; use the grade specified for your exact engine.
- If your build sheet or owner's manual gives a different figure than shown here, trust your own paperwork - regional specifications can vary slightly.

Frequently asked questions
How much oil does a 2.5L non-turbo Mazda CX-5 take?
The 2.5L SkyActiv-G (PY-VPS), used from 2013 through 2023, takes 4.5 liters (4.8 US quarts) of 0W-20 synthetic oil when the filter is also replaced.
Does the CX-5 Turbo need different oil than the standard 2.5L?
Yes. The 2.5L Turbo (PY-VPTS, 2019 and later) needs 4.8 liters (5.1 US quarts) of 5W-30, while the non-turbo 2.5L uses 0W-20 at a slightly lower capacity of 4.5 liters (4.8 US quarts).
Where can I find the exact oil capacity for my specific CX-5?
Open the owner's manual to the Capacities section, or look at the oil filler cap and the engine code sticker under the hood. These are printed for your exact build and override any general online figure.
Can I use 0W-20 in the CX-5 Turbo engine if 5W-30 is not available?
Mazda lists 0W-20 as an acceptable temporary alternative for the 2.5L Turbo in some markets, but the engine should be switched back to 5W-30 at the next oil change - check your owner's manual for the exact allowance in your region.
