Additional Notes
- The front differential on the Lamborghini SIÁN FKP 37 (2021-2022) holds 0.8 liter, and no separate dry fill and service fill values are listed, indicating a single capacity figure applies regardless of whether the unit is being filled from empty or topped up during a routine service.
- The rear differential carries a dry fill capacity of 2 liters, which represents the total volume required when filling a completely drained or overhauled unit from scratch.
- The rear differential service fill capacity is 1.3 liters, a notably lower figure than the dry fill, reflecting the residual fluid that remains in the housing during a standard drain-and-refill procedure rather than a full overhaul.
- Under normal use conditions, both the front and rear differentials share the same check interval of 15,000 km, meaning the fluid level is inspected at that mileage point without necessarily being replaced.
- The normal-use change interval for both differentials is 30,000 km or 24 months, whichever comes first, combining a distance threshold with a time-based limit to account for vehicles that accumulate low mileage over extended periods.
- A first-change-only interval of 2,500 km applies to both the front and rear differentials, a significantly shorter interval than the standard 30,000 km cycle, consistent with the practice of removing break-in contaminants such as metal particles generated during initial component wear-in.
