Mazda 121 (EU)
Automatic transmission fluid capacity & service interval
Mazda 121 (EU) automatic transmission fluid capacity ranges from 3,5 to 6,3 liters. Service intervals include checking at 15000 km/12 months or 40000 km/24 months, and changing at 45000 km/36 months. The data covers 3 configurations.

Additional Notes
- The Mazda 121 (EU) 1.1 and 1.3 variants from 1991-1996 share an identical automatic transaxle capacity of 6.3 liters, a figure typical of a full overhaul or dry fill rather than a routine service top-up.
- By contrast, the 1.25 16V from 1996-2002 carries a notably smaller automatic transaxle capacity of 3.5 liters, reflecting a different transmission unit with a lower total fluid volume.
- The 1991-1996 1.1 and 1.3 specifications list only a check interval under normal use conditions, set at 40,000 km or 24 months, with no separate change interval recorded for either variant.
- The 1.25 16V under normal use conditions carries a fluid check interval of 15,000 km or 12 months, which is considerably shorter than the 40,000 km or 24-month check interval associated with the earlier 1.1 and 1.3 engines.
- A dedicated fluid change interval of 45,000 km or 36 months applies to the 1.25 16V under normal use conditions, a distinction absent from the 1991-1996 engine specifications.
- All three configurations are identified as automatic transaxle units, meaning the transmission and front axle differential share a common fluid reservoir, which accounts for the relatively high 6.3-liter figure seen in the 1.1 and 1.3 variants.
