5W-30 is the turbo-specific factory fill. Do not substitute the naturally aspirated engine's 0W-20. Uses a different cartridge filter than the non-turbo 2.5L.

US-market data on this engine is thin because Mazda sold it for only two model years at very low volume, some third-party oil-selector sites list a smaller ~4.2L capacity for other markets' calibration of this engine; verify against your VIN's build sheet before a first fill. Requires a low-ash oil to avoid clogging the diesel particulate filter. Do not use a gasoline-spec oil.

2017–2025 Mazda CX-5 oil: common questions
How many quarts of oil does a 2017–2025 Mazda CX-5 take?
- It depends on the engine. The 2.5L SkyActiv-G (PY-VPS) takes 4.8 quarts; The 2.5L SkyActiv-G Turbo takes 5.1 quarts; The 2.2L SkyActiv-D (turbodiesel) takes 5.4 quarts, all figures include a new filter.
What kind of oil does a 2017–2025 Mazda CX-5 take?
- 0W-20 meeting API SN/SP or ILSAC GF-5/GF-6, full synthetic (required, not merely recommended). Other engines in this vehicle may differ; see the table above.
Can you use a different viscosity in a 2017–2025 Mazda CX-5?
- The factory specification is 0W-20 and no alternate grade is listed for this engine. Modern variable-valve-timing hardware is sized around the specified viscosity, so substituting a thicker oil is not a free choice.
How often does a 2017–2025 Mazda CX-5 need an oil change?
- 7,500 mi / 12 months (normal, Schedule 1); 5,000 mi / 6 months (severe, Schedule 2). Short trips, towing, extended idling, and dusty or very cold conditions all put the vehicle on the severe-service side of that interval.
What oil filter does a 2017–2025 Mazda CX-5 take?
- The OEM filter is Mazda PE01-14-302 (later PE01-14-302B), cartridge. Common equivalents: Fram XG10575, Wix 57062XP, Purolator L14459.
