Mazda MX-5 / Miata, NA (EU)

Differential fluid capacity & service interval

Mazda MX-5 / Miata, NA (EU) differential fluid capacity ranges from 0,65 to 1 liter. Service intervals include checks at 30000 to 40000 km or 24 months and changes at 80000 to 90000 km or 48 to 72 months. The data covers 3 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The Mazda MX-5 / Miata NA (EU) 1.6 produced from 1990-1993 carries a rear differential fluid capacity of 0.65 liter, which represents a notably small fill volume consistent with the compact rear axle unit found in lightweight roadsters of the period.
  • The 1.6 engine variant from 1994-1997 sees a modest capacity increase to 0.7 liter, indicating a slight difference in the rear differential housing compared to the earlier 1990-1993 version of the same engine displacement.
  • The 1.8 engine variant from 1993-1997 holds a rear differential fluid capacity of 1 liter, a meaningfully larger fill volume than either 1.6 configuration, reflecting the physically larger differential unit paired with the higher-displacement engine.
  • Under normal use conditions, the 1990-1993 1.6 variant specifies a fluid check interval of 40,000 km or 24 months, which is a longer distance threshold than the 30,000 km or 24 months check interval shared by both the 1994-1997 1.6 and the 1.8 variants.
  • The change interval for the 1990-1993 1.6 variant under normal use is set at 80,000 km or 48 months, a shorter interval in both distance and time than the 90,000 km or 72 months change interval specified for the later 1.6 and the 1.8 variants.
  • The 1994-1997 1.6 and the 1993-1997 1.8 variants share identical service intervals of 30,000 km or 24 months for fluid checks and 90,000 km or 72 months for fluid changes, despite differing in rear differential capacity.
