Additional Notes

  • The Mazda CX-30 DM rear differential holds 0.35 liter across all listed AWD configurations, covering both the naturally aspirated SKYACTIV-G 2.5 and the turbocharged SKYACTIV-G 2.5 T variants in Canadian and US markets.
  • A capacity of 0.35 liter is a notably small fill volume, consistent with the compact rear coupling units found in electronically controlled on-demand AWD systems rather than a traditional open differential with a larger housing.
  • All six rows carry a normal use condition, meaning the listed 0.35 liter capacity applies to standard operating environments rather than severe-duty or high-stress driving cycles.
  • The SKYACTIV-G 2.5 T AWD configurations, available from 2020 in both the Canadian and US markets, share the same 0.35 liter rear differential capacity as the non-turbocharged SKYACTIV-G 2.5 AWD, indicating the rear coupling unit is common across both engine variants.
  • The SKYACTIV-G 2.5 AWD appears in two separate row entries per market region, one covering 2019-2022 and one starting from 2022, both specifying the same 0.35 liter capacity, reflecting a continuity of the rear differential specification across that model year boundary.
  • No variation in rear differential fluid capacity exists between the Canadian and US market specifications for any of the listed engine and drivetrain combinations, with all configurations aligned at 0.35 liter under normal use conditions.
