Additional Notes

  • The Mazda Xedos 9 (EU) automatic transmission is configured as a transaxle across all listed engine variants, meaning the transmission and final drive share a single housing, which accounts for the relatively high fluid capacities specified.
  • The 2.5 V6 carries an 8.8-liter transaxle fluid capacity across all model years from 1993-2002, while the 2.3 V6 Miller Cycle is specified at 8 liters, a difference of 0.8 liters between the two engine families.
  • An 8.8-liter capacity in a transaxle application is consistent with a full-system service fill rather than a partial drain-and-refill, indicating the figure represents the total fluid volume held within the unit.
  • The 2.5 V6 in its earliest production span of 1993-1996 carries a check interval of 20,000 km or 12 months under normal use conditions, which is a notably shorter interval compared to all other configurations listed.
  • From 1997 onward, the 2.5 V6 shifts to a 24-month or 30,000 km check interval under normal use, aligning with the interval applied to the 2.3 V6 Miller Cycle across its entire production span of 1995-2001.
  • The 2.3 V6 Miller Cycle, covering model years 1995-2001, maintains a consistent 8-liter capacity and a 24-month or 30,000 km check interval throughout, with no variation between the 1995-2000 and 2001 sub-ranges in either capacity or service schedule.
  • The convergence of the 2.5 V6 onto the same 24-month or 30,000 km interval as the 2.3 V6 Miller Cycle from 1997 onward means that despite the capacity difference between the two engines, the service timing is identical across the majority of the model range.
