Additional Notes

  • The Mazda MX-5 / Miata NC rear differential holds 0.7 liter across all listed configurations, spanning both the 118 kW and 125 kW engine variants and covering the full 2005-2015 model range.
  • A 0.7 liter capacity is a relatively small fill volume, consistent with the compact rear differential unit found in a lightweight two-seat roadster platform.
  • Under normal use conditions, the rear differential fluid change interval is set at 60,000 miles or 48 months for both the 118 kW and 125 kW variants across 2005-2015.
  • Under severe use conditions, the change interval is halved to 30,000 miles or 24 months, applying equally to both engine outputs and both model year groupings.
  • The time-based component of the severe interval, 24 months, means fluid replacement is due every two years regardless of mileage accumulation, which reflects the degradation that occurs from heat cycling and moisture ingress over time.
  • The 118 kW and 125 kW engine variants share identical rear differential fluid capacities and service intervals across both the 2005-2010 and 2010-2015 groupings, indicating no differentiation in differential specification between those two power outputs.
  • The split between the 2005-2010 and 2010-2015 model year groupings appears in the specifications for both engine variants, yet the capacity and interval values remain unchanged across those two periods.
