Additional Notes

  • The rear differential on the Mazda RX-7 SA (EU) holds 1.2 liters of fluid, a figure consistent with the compact rear axle units found in lightweight sports cars of the era.
  • A change interval of 35,000 km or 36 months is specified for normal use conditions, meaning the interval applies to typical driving rather than demanding or high-stress operation.
  • The 36-month time limit runs alongside the 35,000 km distance threshold, so whichever of the two is reached first would govern when a fluid change is due.
  • The 1.2-liter capacity reflects a service fill volume, representing the amount of fluid needed when draining and refilling the differential under normal maintenance rather than a full overhaul disassembly.
  • A single specification row covers the full 1978-1985 model range, indicating no variation in rear differential fluid capacity or change interval across those years for the EU-market SA series.
