Mazda 3, BM/BN (EU)

Automatic transmission fluid capacity & service interval

Mazda 3, BM/BN (EU) automatic transmission fluid capacity ranges from 2,5 to 8 liters. Service intervals require checks every 20000 km or 12 months. The data covers 6 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The 1.6 automatic transaxle carries a dry fill capacity of 7 liters, which represents the total fluid volume required when filling a completely empty unit, such as after a full rebuild or replacement. The overhaul capacity of 4.5 liters and service fill of 2.5 liters reflect progressively smaller volumes used when some residual fluid remains in the system.
  • The 2.5-liter service fill on the 1.6 transaxle is notably lower than the service fill figures on the SKYACTIV variants, indicating that routine fluid exchanges on the 1.6 displace a smaller portion of the total fluid volume held in the unit.
  • The Mazda 3 SKYACTIV-D 1.5 (77 kW) and all SKYACTIV-G variants share an identical dry fill capacity of 7.8 liters, pointing to a common transaxle design across those petrol and diesel engine pairings.
  • The SKYACTIV-D 2.2 (110 kW) carries the largest dry fill capacity in the lineup at 8 liters, which is consistent with the heavier torque loads a 110 kW diesel engine places on the transmission unit.
  • The SKYACTIV-D 2.2 (110 kW) service fill is listed as a range of 3.5 to 4.9 liters rather than a fixed value. A variable service fill range typically reflects differences in how much fluid drains depending on the drain method used or the number of drain-and-fill cycles performed during a single service.
  • The SKYACTIV-D 1.5 (77 kW) and SKYACTIV-G 2.0 (121 kW) share a 3.3-liter service fill but have no check interval listed in the specifications, unlike several other variants in the same range.
  • The SKYACTIV-D 2.2 (110 kW), SKYACTIV-G 1.5 (74 kW), and SKYACTIV-G 2.0 (88 kW) all carry a fluid check interval of 20,000 km or 12 months under normal use conditions. The 12-month time limit means the interval is triggered by whichever threshold is reached first, regardless of mileage accumulated.
  • All six configurations are specified under normal use conditions, meaning the listed capacities and intervals apply to standard operating environments rather than severe-duty cycles such as frequent towing, extreme temperatures, or predominantly short-trip driving.
