Mazda 929 (EU)

Manual transmission fluid capacity & service interval

Mazda 929 (EU) manual transmission fluid capacity ranges from 2 to 2,5 liters. Service intervals include checking every 10000 km or 6 months, and changing every 15000 km or 12 months up to 40000 km or 24 months. The data covers 5 configurations.

Additional Notes

  • The Mazda 929 (EU) manual transmission fluid capacity holds at 2 liters across the 2.0, 2.0i, 2.2, and 2.2i variants, indicating a consistent gearbox size shared among those four configurations regardless of engine displacement or fuel delivery type.
  • The 929 3.0i (1987-1992) carries a notably larger manual transmission fluid capacity of 2.5 liters, a 25% increase over the 2-liter figure seen in the other variants, which reflects a physically larger gearbox unit paired with the bigger engine.
  • The 929 2.0 (1984-1987) specifies a single change interval of 15,000 km or 12 months under normal use conditions, with no separate fluid level check interval listed alongside it.
  • Starting with the 1987-1992 variants, the service structure shifts to a two-stage schedule: a fluid level check at 10,000 km or 6 months, and a full fluid change at 40,000 km or 24 months, both under normal use conditions.
  • The change interval for the 929 2.0 (1984-1987) at 15,000 km stands considerably shorter than the 40,000 km change interval applied to all 1987-1992 variants, representing a significant difference in scheduled maintenance frequency between the two generations.
  • The 10,000 km or 6-month check interval introduced across the 1987-1992 range serves as an intermediate inspection point, distinct from the full drain-and-fill service due at 40,000 km or 24 months.
  • All five configurations carry normal use condition designations, meaning none of the listed intervals are adjusted for severe operating conditions such as towing, extreme temperatures, or frequent short-distance driving.
  • The 2.2 and 2.2i variants (1987-1992) share identical capacity and interval specifications with the 2.0i of the same period, despite the difference in engine displacement, pointing to the same transmission unit being used across those three variants.
