Mazda CX-30 Oil Change Interval & Oil Type
When to change the oil on a 2020-2024 (DM) Mazda CX-30, and what oil it takes.
| Oil change interval | Every 5,000 mi / 6 mo |
|---|---|
| Engine / oil | 2.5L SKYACTIV-G NA or 2.5L Turbo; 0W-20 synthetic; 6-speed conventional auto |
| Oil filter | Replace with every oil change |
Mazda CX-30 note: Same recipe as the Mazda3 it's based on: real torque-converter automatic (so do the ATF), short 5,000-mi oil, and a notably early ~40k plug interval if you have the 2.5 Turbo.
