Mazda Capella/616/626 (EU)

Differential fluid capacity & service interval

Mazda Capella/616/626 (EU) differential fluid capacity is 1,2 liters. Service intervals include checks at 10000 km or 6 months and changes at 1000 km, 10000 km or 6 months, 20000 km or 12 months, and 50000 km or 30 months. The data covers 8 configurations.

Additional Notes

  • The rear differential fluid capacity across all listed configurations, from the Mazda Capella/616/626 (EU) SNA generation through the CB generation, holds at a uniform 1.2 liters, which is consistent with a compact rear differential unit requiring a relatively modest service fill volume.
  • The SNA 1600 (1973-1978) carries an initial service fluid change interval of 1,000 km, a notably short break-in interval intended to flush metal particles generated during the differential's early wear-in period.
  • Under normal use conditions, the SNA 1600 (1973-1978) specifies a differential fluid change at 20,000 km or 12 months, while the CB generation (1978-1983) extends the normal change interval considerably to 50,000 km or 30 months, reflecting a significant revision in service scheduling between the two generations.
  • The CB generation's initial service change interval is set at 10,000 km or 6 months, which is ten times the distance specified for the SNA generation's initial service, indicating a different approach to early differential fluid maintenance between the two generations.
  • Across all three CB engine variants, the 1600, 1800, and 2000, both the normal and initial service specifications are identical, with no variation in capacity or interval tied to engine displacement within the CB generation.
  • The normal use condition for both the SNA and CB generations includes a fluid level check interval of 10,000 km or 6 months, separate from and more frequent than the full fluid change interval, reflecting standard practice for monitoring rear differential fluid integrity between changes.
