Additional Notes

  • The Buick Enclave 3.6L V6 AWD rear differential holds 0.75 liter across both the 2017-2022 and 2022-2024 configurations, a figure consistent with a service fill rather than a full overhaul capacity.
  • Under normal use conditions, the rear differential fluid change interval is set at 150,000 miles for the 3.6L V6 AWD in both covered model year ranges.
  • Under severe use conditions, the rear differential change interval is halved to 75,000 miles, while the fluid capacity of 0.75 liter remains unchanged from the normal use specification.
  • The rear differential clutch carries a separate fluid capacity of 0.35 liter, a notably smaller volume that reflects the compact, dedicated nature of the clutch pack assembly within the AWD system.
  • No change interval is listed for the rear differential clutch fluid in either model year range, with only a capacity figure of 0.35 liter recorded under normal use conditions.
  • The rear differential and rear differential clutch are treated as two distinct fluid compartments, each with independent capacity specifications rather than a single combined fill figure.
