Mazda 929 (EU)

Differential fluid capacity & service interval

Mazda 929 (EU) differential fluid capacity is 1,2 liters. Service intervals include checking every 10000 km or 6 months, and changing every 35000 km or 36 months, or 40000 km or 24 months. The data covers 5 configurations.

Additional Notes

  • All five configurations of the Mazda 929 (EU) share an identical rear differential fluid capacity of 1.2 liters, spanning the 2.0, 2.0i, 2.2, 2.2i, and 3.0i engine variants across the 1984-1992 model range.
  • A 1.2-liter capacity figure for a rear differential is a relatively modest fill volume, consistent with a compact rear axle housing rather than a heavy-duty or truck-type differential assembly.
  • Every configuration carries a fluid check interval of 10,000 km or 6 months under normal use conditions, whichever comes first, indicating a semi-annual inspection cycle regardless of engine displacement.
  • The 929 2.0 covering 1984-1987 has a fluid change interval of 35,000 km or 36 months under normal use, making the time-based threshold notably longer than what is specified for the later variants.
  • The 2.0i, 2.2, 2.2i, and 3.0i variants from 1987-1992 all share a change interval of 40,000 km or 24 months under normal use, which is a shorter time-based interval than the 36-month period assigned to the earlier 2.0.
  • The shift from a 36-month to a 24-month time-based change interval between the 1984-1987 2.0 and the 1987-1992 variants means the later engines require a fluid change up to 12 months sooner on a calendar basis, despite the higher mileage threshold of 40,000 km versus 35,000 km.
  • The 3.0i variant, despite having the largest engine displacement in the lineup, carries the same 1.2-liter rear differential capacity and the same 40,000 km or 24-month change interval as the 2.0i, 2.2, and 2.2i configurations.
