Additional Notes

  • The Mazda 6 GG/GY (EU) 2.3 S-VT AWD rear differential holds a capacity of 1 liter, a figure consistent with a compact rear differential unit rather than a larger transfer case or transaxle assembly.
  • The 1-liter capacity remains the same across both normal and severe use conditions, meaning the fill volume does not change regardless of operating environment.
  • Under severe use conditions, the rear differential fluid on the 2.3 S-VT AWD carries a specified change interval of 40,000 km or 48 months, whichever comes first.
  • The 48-month time limit paired with the 40,000 km distance interval under severe use reflects a dual-trigger service approach, where either threshold alone is sufficient to require a fluid change.
  • No change interval is listed under normal use conditions, with only the 1-liter capacity specified for that row.
