Mazda 3, BL (EU)

Automatic transmission fluid capacity & service interval

Mazda 3, BL (EU) requires automatic transmission fluid with a capacity range of 3 to 5 liters. Service intervals consist of checks every 20000 km or 12 months. The data covers 2 configurations.

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

Additional Notes

  • Both the 1.6 and 2.0 engine variants of the Mazda 3 BL (EU) share identical automatic transaxle fluid capacities, with a dry fill of 5 liters and a service fill of 3 liters.
  • The dry fill figure of 5 liters represents the total fluid volume required when filling a completely empty or overhauled transmission, including fluid held within the torque converter and internal passages.
  • The service fill of 3 liters reflects the smaller volume needed during a routine fluid change, where residual fluid remains in the torque converter and other internal cavities after draining.
  • The gap between the 5-liter dry fill and the 3-liter service fill indicates that approximately 2 liters of fluid is retained within the transaxle assembly during a standard drain procedure.
  • The check interval for automatic transaxle fluid on both the 1.6 and 2.0 variants is set at 20,000 km or 12 months, whichever comes first, under normal use conditions.
  • The 12-month time component of the check interval means that calendar time functions as an independent trigger, regardless of whether the 20,000 km distance threshold has been reached.
