Additional Notes
- The Holden Statesman HQ rear differential holds 1.42 liters across all listed engine and differential configurations spanning 1971-1974.
- Both the 308 HC and 350 HC engine variants share an identical rear differential capacity of 1.42 liters, indicating no displacement-related variation in the differential housing size.
- The limited slip differential variants for both the 308 HC and 350 HC also carry a 1.42-liter capacity, matching the standard open differential specification exactly.
- A check interval of 10,000 km or 6 months, whichever comes first, applies uniformly under normal use conditions across all four configurations listed.
- The dual-interval format of 10,000 km or 6 months means the differential fluid level is due for inspection based on whichever threshold is reached first, accounting for both high-mileage and low-mileage driving patterns.
