Additional Notes
- The Fiat 520 (EU) rear differential holds 3.6 liters of fluid, a relatively substantial capacity that reflects the full-volume fill expected during a service interval rather than a partial top-up.
- Under normal use conditions, the rear differential fluid change interval is set at 3,000 km, indicating a fairly frequent replacement schedule by modern standards.
- The 3.6-liter capacity paired with a 3,000 km change interval means fluid turnover in the rear differential occurs at a high rate relative to total fluid volume, which is consistent with maintenance practices common to vehicles of the late 1920s era.
