Additional Notes

  • The Genesis G80 RG3 rear differential holds 1.3 liters of fluid across all four configurations covered in the specifications, meaning the 2.5 T-GDI, 2.5 T-GDI AWD, 3.5 T-GDI, and 3.5 T-GDI AWD all share an identical rear differential fluid capacity.
  • AWD variants of the G80 RG3 carry an additional front differential with a capacity of 0.7 liters, which is roughly half the volume of the rear differential on the same vehicle.
  • Under normal use conditions, the rear differential fluid interval is specified as a check at 32,000 miles or 48 months, whichever comes first, rather than a full fluid change.
  • Under severe use conditions, the rear differential fluid interval shifts from a periodic check to an outright change at 72,000 miles, applying equally to the 2.5 T-GDI and 3.5 T-GDI configurations.
  • The front differential on AWD variants follows the same interval structure as the rear: a fluid check at 32,000 miles or 48 months under normal conditions, and a fluid change at 72,000 miles under severe conditions.
  • The 72,000-mile severe-use change interval applies to both the front and rear differentials on AWD models, meaning a single service event at that mileage point would address both units simultaneously.
  • The rear differential capacity of 1.3 liters is consistent across both the 2.5 T-GDI and 3.5 T-GDI engine variants, indicating the engine displacement has no bearing on rear differential fluid volume in the G80 RG3 specifications.
