What each service does
Oil & Filter Change
Mazda's Skyactiv-G engines take 0W-20 full synthetic, serviced every 12,000 km / 7,500 mi or 12 months.
Tire Rotation
Rotating tires with each oil change evens out tread wear for longer tire life.
Engine Air Filter
A clean air filter protects power and economy; replaced around 48,000 km / 30,000 mi.
Cabin Air Filter
Filters dust and pollen from the cabin air, roughly once a year.
Spark Plugs
Mazda's naturally-aspirated Skyactiv plugs last around 120,000 km / 75,000 mi.
Engine Coolant (FL-22)
Mazda's FL-22 long-life coolant carries a long first interval before its protection needs renewing.
Automatic Transmission Fluid
Clean fluid keeps the automatic shifting smoothly; Mazda schedules it by inspection under normal driving.
Brake Fluid
Brake fluid absorbs moisture over time; Mazda replaces it on a 2-year clock.
