Aston Martin DB4
Differential fluid capacity & service interval
Aston Martin DB4 differential fluid capacity is 1,7 liters. Service intervals include checking every 4000 km or 6 months and changing every 16000 km or 18 months. The data covers 3 configurations.

Additional Notes
- The rear differential fluid capacity across all three DB4 configurations — the standard DB4 (1958-1963), the DB4 GT Zagato (1960-1963), and the DB4 Vantage (1962-1963) — is listed at 1.7 liters, a figure consistent with a service fill rather than a full overhaul quantity.
- A 1.7-liter service fill capacity is relatively modest, which is typical of a rear differential unit in a grand touring car of the late 1950s and early 1960s, where the housing volume is sized around a compact hypoid gear assembly.
- The fluid check interval for the Aston Martin DB4 rear differential is specified at every 4,000 km or 6 months under normal use conditions, whichever comes first.
- The fluid change interval is set at 16,000 km or 18 months under the same normal use conditions, meaning a full drain-and-refill cycle occurs roughly once every four check intervals.
- The ratio of check interval to change interval — four checks per one change — reflects a maintenance schedule designed to monitor fluid condition and level regularly while extending the full replacement cycle over a longer period.
- All three configurations share identical check and change intervals, meaning the DB4 GT Zagato and DB4 Vantage variants carry no differentiated differential service schedule despite their distinct performance specifications relative to the base model.
