Additional Notes

  • The Mazda 3 BM/BN (EU) 1.6 manual transaxle holds 2.9 liters of fluid, the largest capacity across all listed configurations. A higher transaxle fluid volume generally corresponds to a physically larger gearbox housing, which is typical of older non-SKYACTIV drivetrain designs.
  • All three SKYACTIV-G petrol variants share a 1.7-liter transaxle capacity regardless of power output, with the 74 kW, 88 kW, and 121 kW engines all specifying the same fill volume. This indicates a common manual transaxle unit across the SKYACTIV-G petrol range in the BM/BN generation.
  • The SKYACTIV-D 1.5 (77 kW) carries the smallest transaxle fluid capacity at 1.65 liters, while the SKYACTIV-D 2.2 (110 kW) requires 2.4 liters. The difference reflects the larger physical dimensions of the six-speed unit typically paired with the 2.2-liter diesel compared to the lighter gearbox used with the smaller diesel engine.
  • Every configuration listed specifies a 180,000 km change interval under normal use conditions. In the context of manual transmission servicing, a 180,000 km interval is considered an extended-life schedule, reflecting fluid formulations designed to maintain lubrication properties over long service periods without degradation under standard driving conditions.
  • The SKYACTIV-D 2.2 (110 kW) transaxle capacity of 2.4 liters sits between the SKYACTIV-G figure of 1.7 liters and the 1.6 non-SKYACTIV figure of 2.9 liters, placing the larger diesel gearbox in a mid-range position by fluid volume among the BM/BN manual transmission lineup.
  • The 1.6 petrol variant covers model years 2017-2019, a narrower window than the SKYACTIV configurations, several of which span the full 2013-2019 range. Despite the shorter production window, the 1.6 retains the same 180,000 km fluid change interval as all other listed variants.
