Additional Notes

  • The Lamborghini Islero rear differential holds 1.55 liters of fluid across all listed configurations for 1966-1968, a capacity typical of a compact rear differential unit found in grand touring vehicles of the era.
  • Both the standard Islero and the Islero GT share an identical rear differential fluid capacity of 1.55 liters, indicating no volumetric difference between the two trim levels in the differential housing.
  • The limited slip differential variants across both the Islero and Islero GT also carry the same 1.55-liter capacity as their open differential counterparts, meaning the internal clutch pack assembly of the limited slip unit does not alter the overall fluid volume requirement.
  • A 6,000-mile change interval applies uniformly to all four configurations under normal use conditions, placing rear differential service on a relatively frequent schedule compared to many modern vehicles, which reflects maintenance standards common to high-performance machinery of the 1960s.
