Aston Martin DB9

Power steering fluid capacity & service interval

Aston Martin DB9 uses power steering fluid with a capacity of 1,3 liters. Service intervals occur every 16000 km or 12 months. The data covers 7 configurations.

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

Additional Notes

  • The Aston Martin DB9 power steering system holds 1.3 liters across all listed configurations, from the 2003-2008 models through to the 2014-2016 and DB9 GT 2015-2016 variants. In hydraulic power steering systems, this figure represents the total fluid volume the reservoir and circuit hold, which is a relatively modest capacity consistent with a dedicated rack-and-pinion hydraulic assist setup.
  • The 1.3-liter capacity figure applies uniformly across every DB9 configuration in the specifications, covering the standard DB9 across its 2003-2016 production span as well as the DB9 GT from 2015-2016. No variation in capacity exists between any of the listed model year ranges or trim designations.
  • The service interval for all listed configurations is a fluid check at 16,000 km or 12 months, whichever comes first. The dual-trigger format, combining a distance threshold with a fixed time period, means the interval is governed by whichever condition is reached earlier, which is relevant for vehicles that accumulate low annual mileage.
  • All seven rows carry a normal use condition tied to the 16,000 km / 12-month check interval. In service classification terms, normal use typically refers to standard driving conditions without the additional stress factors, such as frequent towing, extreme temperatures, or sustained low-speed operation, that would otherwise shorten service intervals.
  • The DB9 GT, spanning 2015-2016, shares an identical power steering capacity and check interval with the standard DB9 of the same period. No specification differentiation exists between the GT designation and the base DB9 for this system.
  • The interval specified is a fluid check rather than a fluid replacement. A check interval indicates a scheduled inspection of fluid level and condition, which is a distinct service action from a full drain-and-fill procedure. The specifications do not assign a separate replacement interval distinct from the check interval for any listed configuration.
