2017–2025 Mazda CX-5 maintenance schedule
Schedule type: oil-life monitor (Mazda Engine Oil Flexible Maintenance)
In the U.S., the car tracks oil life and lights a wrench when an oil change is due. Change it within 600 miles or 15 days of the light, and never go past 7,500 miles or 12 months. Reset the setting after each oil change. Summarized in our own words from the sources listed. Always follow the owner's manual or your dealer for your specific vehicle (VIN, engine, and options).
Checked against the official document for model year 2021; other years in this range are assumed to follow it. Confirm in your owner's manual.
