Lamborghini SIÁN Roadster

Differential fluid capacity & service interval

Lamborghini SIÁN Roadster differential fluid capacity ranges from 0,8 liter to 2 liter. Service intervals include checks at 15000 km and changes at 2500 km or 30000 km/24 months. The data covers 4 configurations.

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

Additional Notes

  • The Lamborghini SIÁN Roadster front differential holds 0.8 liter, with no distinction between dry fill and service fill values, indicating a single capacity figure applies regardless of whether the unit is being filled from empty or topped up during routine service.
  • The rear differential carries two separate capacity figures: 2 liters for a dry fill and 1.3 liters for a service fill. The dry fill figure reflects the total volume required when the unit is completely empty, such as after a full overhaul or component replacement, while the service fill figure reflects the smaller volume needed during a standard fluid change.
  • Both the front and rear differentials share a first-change interval of 2500 km, a break-in service designed to remove metal particles and contaminants generated during initial component wear-in before the normal service schedule takes over.
  • Under normal use conditions, both the front and rear differentials follow a check interval of every 15000 km, allowing fluid level and condition to be assessed without a full drain and refill at that point.
  • The normal-use change interval for both differentials is set at 30000 km or 24 months, whichever comes first, meaning time elapsed can trigger a fluid change even when the mileage threshold has not been reached.
