Additional Notes

  • The Mazda MX-5 / Miata NC (EU) manual transmission fluid capacity is listed at either 2.0 liters or 2.1 liters depending on the specific configuration, with both values appearing across the 2005-2015 model range.
  • The 2.1-liter capacity figure appears exclusively within the 2.0-engine variants, covering both the 2005-2011 and 2011-2015 production periods, while the 1.8-engine variants are listed solely at 2.0 liters.
  • A manual transmission fluid capacity of 2.0 liters is a standard service fill volume for a small rear-wheel-drive sports car gearbox, reflecting the compact unit fitted to the NC generation.
  • The 0.1-liter difference between the two 2.0-engine capacity entries likely corresponds to a variation between gearbox variants or fill procedures, as a dry or overhaul fill can differ slightly from a standard drain-and-refill service quantity.
  • All six specification rows carry a normal use condition, meaning the 100,000 km or 60-month change interval applies to standard driving circumstances rather than severe or demanding operating conditions.
  • The 60-month time limit runs concurrently with the 100,000 km distance interval, so whichever threshold is reached first would govern the service point under normal use.
  • The 1.8-liter engine variant spans 2005-2011, and the manual transmission fluid specification for that period is a single consistent entry at 2.0 liters with no alternate capacity listed.
  • Both the 2005-2011 and 2011-2015 periods for the 2.0-engine share identical interval values of 100,000 km and 60 months, with the only variation between entries being the 2.0 versus 2.1-liter capacity figures.
