Holden Brougham, HK/HT/HG

Differential fluid capacity & service interval

Holden Brougham, HK/HT/HG differential fluid capacity ranges from 1,42 to 1,88 liters. Service intervals require a check every 10000 km. The data covers 8 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The Holden Brougham HK/HT/HG rear differential fluid check interval is set at 10,000 km across all listed configurations under normal use conditions.
  • The HK 307 (1968-1969) rear differential, in both standard and limited slip forms, carries a single capacity figure of 1.42 liters, indicating no variation between differential types for that engine and series.
  • The HG and HT 308 HC (1969-1970) rear differential specifications list two distinct capacities depending on differential build: 1.65 liters for the Standard unit and 1.88 liters for the Heavy Duty unit, reflecting a meaningful difference in housing size between the two.
  • A separate 1.42-liter capacity entry exists for the HG and HT 308 HC rear differential, distinct from the Standard and Heavy Duty figures, suggesting a third differential variant is present in the specifications for those series.
  • The limited slip rear differential on the HG and HT 308 HC (1969-1970) carries a capacity range of 1.42-1.88 liters, which spans the full range of values seen across all rear differential entries for those series, indicating the limited slip unit was fitted with more than one housing size.
  • The limited slip rear differential on the HK 307 (1968-1969) holds 1.42 liters, matching the standard rear differential capacity for the same series, meaning the limited slip variant in the HK did not require a larger housing fill volume.
