Additional Notes

  • The Mazda MX-5 / Miata NA (EU) manual transmission holds 2 liters of fluid across all three configurations covered by the specifications, spanning both the 1.6 and 1.8 engine variants.
  • A 2-liter fill capacity is a relatively modest volume for a manual gearbox, consistent with the compact, lightweight transmission design typical of small rear-wheel-drive sports cars of the era.
  • The 1.6-liter variant produced from 1990-1993 and the revised 1.6-liter variant from 1994-1997 share identical fluid capacity and service interval figures, indicating no change in transmission fluid requirements between those two production periods.
  • The 1.8-liter variant introduced from 1993-1997 also carries the same 2-liter capacity and identical check and change intervals as the 1.6-liter configurations, despite the larger displacement engine.
  • Under normal use conditions, the specified fluid check interval is 45,000 km or 36 months across all three configurations, meaning the transmission fluid level is due for inspection roughly every three years or every 45,000 km, whichever comes first.
  • The fluid change interval under normal use is set at 90,000 km or 72 months for all configurations, placing a full drain-and-refill on a six-year or 90,000 km cycle.
  • The check interval of 45,000 km / 36 months falls at exactly the halfway point of the 90,000 km / 72-month change interval, structuring fluid maintenance into two equal monitoring periods before a full replacement is due.
