Mazda CX-9 Oil Change Interval & Oil Type
When to change the oil on a 2016-2023 (TC, 2.5L Turbo) Mazda CX-9, and what oil it takes.
| Oil change interval | Every 5,000 mi / 6 mo |
|---|---|
| Engine / oil | 2.5L Turbo only (SKYACTIV-G 2.5T); 0W-20 synthetic; 6-speed conventional auto |
| Oil filter | Replace with every oil change |
Mazda CX-9 note: Turbo-only, so the ~40k spark-plug interval applies to every CX-9 — much sooner than NA rivals. Real torque-converter auto (do the ATF) and Mazda's short 5,000-mi oil interval.
