Additional Notes
- The differential fluid capacity across all Aston Martin DB9 configurations from 2003-2016 is 1.6 liters. This figure represents a service fill volume, meaning the amount required when draining and refilling the differential under normal service conditions rather than a full overhaul or bench-fill procedure.
- All specifications listed apply to normal use conditions, meaning standard road driving as opposed to track, towing, or other high-stress operating environments.
- The note "from automatic" indicates the differential fluid specification applies to vehicles equipped with an automatic transmission, as the drivetrain configuration influences how the rear differential is loaded and serviced.
- For the DB9 covering model years 2003-2012, the service schedule specifies only a fluid change interval, set at 32,000 km or 24 months, whichever comes first. No intermediate inspection interval is listed for these earlier configurations.
- Beginning with the 2012-2014 DB9, the service schedule introduces a two-stage approach. A fluid level check is specified at 32,000 km or 24 months, while the full fluid change interval is extended to 64,000 km or 48 months. This represents a notable shift from the simpler single-interval schedule used in earlier model years.
- The extended change interval of 64,000 km or 48 months, introduced from 2012 onward, is double the 32,000 km or 24-month change interval specified for the 2003-2012 configurations, while the capacity remains unchanged at 1.6 liters across both service regimes.
- The DB9 GT, covering 2015-2016, shares the same 1.6-liter differential fluid capacity and the same two-stage check and change schedule as the standard DB9 of the same period, indicating no differentiation in differential service requirements between the GT trim and the standard model.
