Additional Notes

  • The Mazda MX-5 / Miata NB (EU) manual transmission fluid capacity is listed at either 2 liters or 1.75 liters depending on the configuration, with both values representing a service fill rather than a full overhaul quantity.
  • The 2-liter capacity applies to both the 1.6 and 1.8 engine variants across the 1997-2000 and 2000-2005 model year ranges, pairing with a check interval of 45,000 km or 36 months under normal use conditions.
  • A separate 1.75-liter capacity figure is listed for both the 1.6 and 1.8 variants within the 2000-2005 range, representing a notably more frequent check interval of 15,000 km or 12 months under normal use conditions.
  • Despite the difference in capacity and check intervals between the two 2000-2005 configurations, the fluid change interval remains consistent at 90,000 km or 72 months across all six rows.
  • The 1997-2000 entries for both the 1.6 and 1.8 engines share identical specifications: a 2-liter capacity, a 45,000 km or 36-month check interval, and a 90,000 km or 72-month change interval under normal use conditions.
  • The 15,000 km or 12-month check interval tied to the 1.75-liter configurations is three times more frequent than the 45,000 km or 36-month interval tied to the 2-liter configurations, indicating a meaningfully different service cadence for those setups.
  • The 72-month change interval, shared across all configurations, translates to a 6-year fluid replacement cycle, which is a relatively extended period for manual transmission fluid in normal use conditions.
