Genesis G90, RS4 (USA)

Differential fluid capacity & service interval

Genesis G90 and RS4 (USA) models utilize differential fluid with capacities ranging from 0,7 to 1,3 liters. Service intervals include checks every 32000 miles or 48 months and fluid changes every 72000 miles. The data covers 10 configurations.

Additional Notes

  • The Genesis G90 3.5 T-GDI rear differential holds 1.3 liters of fluid across all three configurations — the rear-wheel-drive variant, the AWD variant, and the AWD MHEV variant.
  • The front differential on both AWD configurations carries a capacity of 0.7 liter, which is notably smaller than the 1.3-liter rear differential capacity on the same vehicles.
  • Under normal use conditions, the rear differential fluid interval is listed as a check at 32,000 miles or 48 months, rather than a full fluid change, meaning the service action at that interval is inspection rather than replacement.
  • Under severe use conditions, the rear differential fluid on the 3.5 T-GDI is scheduled for a change at 72,000 miles, which is a mileage-only interval with no time component listed alongside it.
  • The front differential on both AWD configurations follows the same interval structure as the rear: a check at 32,000 miles or 48 months under normal use, and a fluid change at 72,000 miles under severe use.
  • The 0.7-liter front differential capacity on the AWD and AWD MHEV configurations is consistent between those two drivetrains, indicating no capacity difference between the standard AWD and the mild hybrid variant at the front axle.
  • The presence of both a mileage threshold and a time threshold (48 months) in the normal-use check interval means whichever limit is reached first would trigger the inspection, regardless of how many miles have accumulated.
