Additional Notes

  • All listed configurations of the Mazda 3 BP carry a transfer case fluid capacity of 0.35 liter, which is a notably small volume consistent with the compact, electronically controlled transfer units found in passenger car-based AWD systems rather than traditional truck-style transfer cases.
  • A capacity as low as 0.35 liter indicates a sealed or near-sealed unit where fluid volume is minimal by design, and precise fill levels are especially critical given how little margin exists between underfill and overfill.
  • The SKYACTIV-G 2.5 naturally aspirated AWD variant covers both Canadian and US markets across the 2018-2022 range, with the same 0.35 liter transfer case capacity applying uniformly across both markets.
  • The turbocharged SKYACTIV-G 2.5T AWD variant, available in both Canadian and US markets from 2020 onward, shares the identical 0.35 liter transfer case capacity as the naturally aspirated 2.5 AWD, despite the higher torque output associated with the turbocharged engine.
  • All six listed configurations specify normal use conditions, meaning the stated 0.35 liter capacity applies to standard operating environments rather than severe-duty or high-stress service cycles.
  • The transfer case fluid specifications are categorized under the transferbox note across all rows, distinguishing the unit from the rear differential or front axle, and confirming the capacity figure refers specifically to the transfer case assembly rather than any associated drivetrain component.
