Aston Martin DB5

Differential fluid capacity & service interval

Aston Martin DB5 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 2 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The Aston Martin DB5 4.0 rear differential holds 1.7 liters of fluid, a figure that applies to both the standard and limited slip differential configurations.
  • Both the standard rear differential and the limited slip rear differential share identical service intervals, with a fluid check scheduled at 4,000 km or every 6 months and a full fluid change at 16,000 km or every 18 months.
  • The check interval of 4,000 km or 6 months is notably frequent relative to the change interval, reflecting the importance of monitoring fluid condition and level between full service events on a rear differential.
  • The change interval of 16,000 km or 18 months means the fluid is replaced roughly every four check cycles, whether the mileage or time threshold is reached first.
  • All intervals listed for the DB5 4.0 differential apply under normal use conditions, covering the 1963-1965 model years for both differential variants.
  • A limited slip differential relies on friction-modifying additives in the fluid to function correctly, and the 1.7-liter capacity figure for the DB5 4.0 limited slip unit is the same as the standard rear differential, indicating a shared housing size across both configurations.
