Pasquali Siena

Differential fluid capacity & service interval

Pasquali Siena differential fluid capacity ranges from 4 to 5.5 liters depending on the configuration. The data covers 6 configurations.

Additional Notes

  • The Pasquali Siena 5.30 AR, 5.40 AR, 6.30 RS, and 6.40 RS all share an identical front differential fluid capacity of 4.8 liters, applying uniformly across normal use conditions for the 2011-2023 model years.
  • The 4.8-liter front differential capacity is consistent across both the AR and RS drivetrain designations in the 5.x and 6.x model variants, indicating a shared differential housing size between those configurations.
  • The Siena K60 AR carries a front differential fluid capacity of 5.5 liters, the largest value listed across all Siena variants, reflecting a physically larger or differently engineered differential unit compared to the 5.x and 6.x series.
  • The Siena K60 RS front differential capacity is rated at 4 liters under normal use conditions, which is the smallest capacity figure among all listed Siena configurations and notably lower than the K60 AR despite sharing the same K60 model generation.
  • The divergence between the K60 AR at 5.5 liters and the K60 RS at 4 liters demonstrates that within the same model generation, the AR and RS drivetrain variants can house mechanically distinct front differential assemblies with meaningfully different fluid volumes.
  • All six configurations specify front differential fluid capacity under normal use conditions, meaning the listed capacities apply to standard operating environments rather than severe-duty or first-fill scenarios.
  • The K60 series, covering model years 2015-2023, represents a later introduction relative to the 5.x and 6.x series, which span 2011-2023, and the K60 variants depart from the uniform 4.8-liter figure established across the earlier configurations.
