Mazda RX (EU)

Manual transmission fluid capacity & service interval

Mazda RX (EU) manual transmission fluid capacity ranges from 1,4 to 1,5 liters. Service intervals include checks at 6000 km and changes at 1000 km or 18000 km. The data covers 4 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The Mazda RX-2 (1971-1974) manual transmission holds 1.5 liters of fluid, while the RX-3 (1972-1978) holds a slightly smaller 1.4 liters, representing the only capacity difference between the two models in these specifications.
  • Both the RX-2 and RX-3 share identical normal-use service intervals, with a fluid level check scheduled at every 6,000 km and a full fluid change at every 18,000 km.
  • An initial service change at 1,000 km is specified for both the RX-2 and RX-3, a practice associated with flushing out metal particles and manufacturing residues that accumulate during a transmission's early break-in period.
  • The 1,000 km initial service interval on the RX-2 carries a 1.5-liter capacity, meaning the early drain involves a full transmission fill rather than a partial top-up.
  • The RX-3's 1.4-liter capacity applies equally to both the initial 1,000 km service change and the recurring 18,000 km normal-use change, indicating a complete fluid replacement in each case.
