Quick answer: the 2020–2025 Mazda CX-5 2.5L engine takes 4.8 qt (4.5 L) of SAE 0W-20 with a filter change. The 2.5L turbo takes 5.1 qt (4.8 L) of SAE 5W-30.
| Engine | Oil capacity (with filter) | Oil type |
|---|---|---|
| 2.5L SKYACTIV-G (non-turbo) | 4.8 qt (4.5 L) | 0W-20 |
| 2.5L SKYACTIV-G Turbo | 5.1 qt (4.8 L) | 5W-30 |
The turbo uses a different oil. Check whether your engine is the 2.5 Turbo before buying 0W-20.
