Additional Notes

  • The Mazda MX-5 ND (EU) manual transmission holds 2 liters of fluid, which represents the full service fill volume for the transmission unit itself.
  • A separate gear case capacity of 0.27–0.31 liters is listed alongside the main transmission volume, indicating a distinct lubrication point that requires its own fill quantity during service.
  • The gear case range of 0.27–0.31 liters reflects a tolerance band rather than a fixed value, meaning the accepted fill level falls within that window rather than at a single precise point.
  • Both the 1.5-liter SKYACTIV-G (96 kW) and the 2.0-liter SKYACTIV-G (118 kW) variants covering 2015-2018 share identical manual transmission fluid capacities of 2 liters and 0.27–0.31 liters for the gear case.
  • The later 1.5-liter SKYACTIV-G (97 kW) and 2.0-liter SKYACTIV-G (135 kW) variants introduced from 2018 onward carry the same 2-liter transmission capacity and 0.27–0.31-liter gear case specification as the earlier power outputs.
  • The power output difference between the 96 kW and 97 kW versions of the 1.5-liter engine, and between the 118 kW and 135 kW versions of the 2.0-liter engine, produces no variation in manual transmission fluid capacity or service interval across the specifications.
  • The service interval across all four configurations is set at 100,000 km or 60 months, whichever comes first, and applies under normal use conditions.
  • A 60-month time limit alongside the 100,000 km distance interval means fluid age alone can trigger a service requirement even when mileage accumulation has been low.
