Additional Notes

  • The Mazda MX-5 / Miata NB (EU) 1.6-liter variants, covering 1997-2005 across both generation splits, carry a rear differential fluid capacity of 0.7 liter.
  • The 1.8-liter variants across the same 1997-2005 span hold a rear differential fluid capacity of 1 liter, which is 0.3 liter more than the 1.6-liter counterparts.
  • The difference in capacity between the two engine variants reflects the physically larger rear differential housing used with the 1.8-liter drivetrain.
  • All four configurations share an identical check interval of every 30,000 km or 24 months under normal use conditions, whichever comes first.
  • The fluid change interval across all configurations is set at 90,000 km or 72 months under normal use, representing a three-to-one ratio relative to the check interval in both distance and time terms.
  • The 72-month change interval means fluid replacement falls approximately every six years when measured by time rather than distance, which can be relevant for lower-mileage vehicles where time accumulation reaches the threshold before the 90,000 km mark.
  • Specifications for the 1.6-liter and 1.8-liter variants are each divided into two sub-ranges, 1997-2000 and 2000-2005, yet the capacity and interval figures remain unchanged between those sub-ranges within each engine family.
