Mazda 3, BK (EU)

Automatic transmission fluid capacity & service interval

Mazda 3, BK (EU) uses automatic transmission fluid with a capacity range of 3 to 7,2 liters. Service intervals occur every 60000 km or 36 months. The data covers 8 configurations.

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

Additional Notes

  • The Mazda 3 BK (EU) 1.4 and the early 1.6 (2003-2006) share a single 7-liter automatic transaxle capacity figure, with no distinction between dry fill and service fill values. A single undifferentiated capacity typically represents the total fluid volume of the unit rather than a routine service quantity.
  • The 1.6 engine variants from 2006-2009 list two separate capacity values: 5 liters for dry fill and 3 liters for service fill. Dry fill refers to the total fluid volume required when filling a completely empty or overhauled transaxle, while service fill reflects the smaller volume needed when replacing fluid during a routine drain-and-refill procedure.
  • The 2.0-liter variants from 2006-2009 carry two separate capacity entries. One lists 7.2 liters without a fill-type qualifier, and the other lists a 5-liter dry fill alongside a 3-liter service fill. The 7.2-liter figure represents a different transaxle unit fitted to the same engine displacement, indicating that two distinct automatic gearbox configurations were used across the 2.0-liter range.
  • The service fill capacity of 3 liters, shared across both the 1.6 (2006-2009) and 2.0 variants, means that a standard fluid exchange replaces only a portion of the total transaxle volume. Fluid retained in the torque converter and valve body is not drained during a typical service, which is why the service fill figure is consistently lower than the dry fill figure.
  • All rows carrying a check interval specify 60,000 km or 36 months under normal use conditions. The 36-month time limit means the interval is reached by whichever threshold, mileage or time, comes first.
  • The 2.0-liter rows for both 2006-2008 and 2009 carry no check interval specification, in contrast to the 1.4 and 1.6 entries, which all include the 60,000 km / 36-month check interval.
  • The 1.6 engine spans three distinct year-range entries: 2003-2006, 2006-2008, and 2009. The 2003-2006 entry uses only a single 7-liter capacity, while the two later entries adopt the dual dry/service fill format, reflecting a transaxle change at some point during the 2006 model year.
