Additional Notes

  • The rear differential fluid capacity across most Mazda 6 GJ/GL AWD configurations is 0.45 liter, a figure consistent with compact rear differential units found in passenger car platforms rather than truck-based or heavy-duty axle assemblies.
  • The SKYACTIV-D 2.2 at 135 kW, covering 2018-2021, carries a notably lower rear differential capacity of 0.35 liter compared to the 0.45 liter specified for the other AWD variants, indicating a physically smaller or differently designed differential unit in that configuration.
  • Under severe use conditions, the SKYACTIV-D 2.2 (110 kW) AWD specifies a rear differential fluid change interval of 45,000 km. Severe use typically encompasses operating conditions such as frequent towing, extended low-speed driving, or repeated short trips that accelerate fluid degradation.
  • The same 45,000 km severe-use change interval applies to the SKYACTIV-D 2.2 (129 kW) AWD covering 2015-2018, with a rear differential capacity also held at 0.45 liter across both normal and severe use entries.
  • No fluid change interval is listed under normal use conditions for any of the AWD configurations in these specifications, meaning the 45,000 km interval is tied exclusively to the severe use designation present in the SKYACTIV-D 2.2 rows.
  • The SKYACTIV-G 2.5 petrol variants, spanning outputs of 141 kW and 143 kW across 2015-2022, all share the 0.45 liter rear differential capacity, with no change interval specified under the normal use condition recorded for each.
  • The SKYACTIV-D 2.2 (129 kW) AWD covers 2015-2018, while the higher-output 135 kW diesel AWD variant begins in 2018, reflecting a mid-range model year transition between two diesel power outputs within the GJ/GL generation.
