Frequently asked
- How often should the Mazda CX-5 II (KF) have an oil change?
- The factory schedule calls for an engine-oil & filter change every 12,500 mi · 20,000 km or 12 mo under normal driving, and every 5,000 mi · 8,000 km under severe duty, verified from the owner's manual.
- Normal vs severe service — which applies to me?
- Severe (or 'special') duty applies to short trips, extreme cold/heat, dusty or stop-and-go driving, towing, or extended idling — most real-world use is closer to severe than many owners assume. When in doubt, follow the severe-duty intervals.
