Aston Martin DB7

Differential fluid capacity & service interval

Aston Martin DB7 differential fluid capacity is 1,6 liters. Service intervals include checks at 12000 km or 6 months, and changes at 24000 km or 12 months, or 48000 km. The data covers 7 configurations.

Additional Notes

  • All Aston Martin DB7 variants across the 1994-2004 model range share a uniform rear differential fluid capacity of 1.6 liters, a figure consistent with a service fill rather than a full overhaul quantity, which would typically account for residual fluid retained in the housing.
  • A check interval of every 12,000 km or 6 months applies across all listed variants under normal use conditions, meaning fluid level and condition are assessed at whichever threshold arrives first.
  • The DB7 (1994-2000) carries a change interval of 48,000 km with no time-based limit specified, making the mileage threshold the sole trigger for a fluid replacement under normal use.
  • The DB7 Vantage (1999-2002), DB7 GT, DB7 GTA, DB7 Zagato, DB7 Vantage (2002-2004), and DB AR1 all share a change interval of 24,000 km or 12 months, which is half the distance interval specified for the earlier DB7 (1994-2000).
  • The addition of a 12-month time limit alongside the 24,000 km distance interval in the later variants means fluid replacement is due at whichever condition is met first, a dual-trigger structure that differs from the mileage-only approach of the 1994-2000 model.
  • The DB7 Vantage appears across two separate year ranges, 1999-2002 and 2002-2004, both carrying identical capacity and interval specifications for the rear differential under normal use conditions.
