Mazda CX-5 Oil Change Interval & Oil Type
When to change the oil on a 2017-2024 (KF gen) Mazda CX-5, and what oil it takes.
| Oil change interval | Every 5,000 mi / 6 mo (shorter than rivals) |
|---|---|
| Engine / oil | 2.5L SKYACTIV-G NA or 2.5L Turbo; 0W-20 synthetic; 6-speed conventional auto (no CVT) |
| Oil filter | Replace with every oil change |
Mazda CX-5 note: Two differentiators vs CVT rivals: (1) a CONVENTIONAL automatic, so normal ATF service applies; (2) the 2.5 TURBO needs spark plugs at ~40k — much sooner than the NA's 75k. Mazda's 5,000-mi oil interval is shorter than most.
