Manual transmission fluid capacity & service interval

Mazda Grand Familia/818 (EU) manual transmission fluid capacity ranges from 1,3 to 1,5 liters. Service intervals include checks at 10000 km or 6 months, changes at 20000 km or 12 months, and an initial change at 1000 km. The data covers 4 configurations.

Additional Notes

  • The 1300 STC variant carries a manual transmission fluid capacity of 1.3 liters, while the 1600 SN4 variant requires 1.5 liters, reflecting the larger gearbox associated with the bigger displacement engine.
  • Both the 1300 STC and 1600 SN4 share an initial service fluid change interval of 1000 km, a break-in procedure intended to flush metal particles and contaminants generated during the early wear-in period of new transmission components.
  • Under normal use conditions, the 1300 STC specifies a fluid check at every 10000 km or 6 months, whichever comes first, with a full fluid change due at 20000 km or 12 months.
  • The 1600 SN4 follows the same normal-use check and change schedule as the 1300 STC, with checks at 10000 km or 6 months and changes at 20000 km or 12 months, despite holding a different fluid volume.
  • The dual-trigger interval structure, combining a distance figure with a time-based figure, means a fluid change on the Mazda Grand Familia/818 is due whichever threshold is reached first, accommodating vehicles driven infrequently where calendar aging of the fluid becomes the limiting factor before mileage accumulates.
