Additional Notes
- The Fiat 518 Ardita 2000 rear differential holds 1.65 liters of fluid, a figure consistent with the compact rear axle housings typical of 1930s passenger cars, where differential sumps were relatively small compared to later commercial vehicle designs.
- The 3,000 km change interval specified for the Ardita 2000 rear differential under normal use conditions reflects the lubrication technology standards of the 1933-1938 production period, when gear oils degraded more rapidly and required far more frequent replacement than modern formulations.
- The 1.65 liter capacity listed for the Ardita 2000 rear differential represents a service fill figure, meaning the volume expected during a routine drain-and-refill procedure rather than a complete overhaul capacity, which would typically account for additional fluid retained in bearings and passages.
