Simca Vedette
Differential fluid capacity & service interval
Simca Vedette differential fluid capacity is 1,2 liters. Service intervals consist of checks every 2000 km or 6 months and changes every 12000 km. The data covers 1 configuration.

Additional Notes
- The Simca Vedette rear differential holds 1.2 liters of fluid, a capacity consistent with a service fill rather than a full overhaul quantity, meaning the housing is serviced with fluid already present and only a partial drain-and-refill volume is expected during routine maintenance.
- Under normal use conditions, the differential fluid change interval is set at 12,000 km, reflecting a relatively short cycle by later automotive standards and typical of engineering practices from the late 1950s and early 1960s.
- A fluid level check is specified at every 2,000 km or every 6 months, whichever comes first, under normal use conditions, pairing a distance-based trigger with a time-based one to account for vehicles driven infrequently as well as those accumulating kilometers quickly.
- The 2,000 km check interval is notably more frequent than the 12,000 km change interval, indicating that monitoring fluid level between full changes was considered a distinct and regular maintenance step for the rear differential on the 1958-1961 Vedette.
