Additional Notes

  • The rear differential on the Buick Enclave 2.5 AWD carries a fluid capacity of 0.95 liter, a figure consistent with a compact rear drive module rather than a traditional open differential housing, reflecting the relatively small volume these integrated AWD rear units require at service fill.
  • Under normal use conditions, the rear differential fluid change interval is set at 150,000 miles, placing routine maintenance well into long-term ownership territory for drivers who do not subject the vehicle to demanding operating conditions.
  • Under severe use conditions, the same rear differential fluid change interval is halved to 75,000 miles, acknowledging that elevated thermal and mechanical stress accelerates fluid degradation in the rear drive unit.
  • The capacity figure of 0.95 liter remains identical across both the normal and severe use rows, confirming that the use condition classification affects only the service interval and not the volume of fluid the rear differential housing holds.
