Aston Martin DB6

Differential fluid capacity & service interval

Aston Martin DB6 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 DB6 4.0 rear differential holds 1.7 liters of fluid, a figure that applies to both the standard open differential and the limited-slip differential variant.
  • Despite the mechanical differences between the standard and limited-slip rear differential configurations, the fluid capacity of 1.7 liters is identical across both setups in the 1965-1971 DB6 4.0.
  • The check interval for both rear differential configurations is set at 4,000 km or every 6 months, whichever comes first, under normal use conditions.
  • The fluid change interval for both rear differential types is 16,000 km or 18 months under normal use conditions, meaning the change cycle is four times longer in distance terms than the check interval.
  • The time-based change interval of 18 months is notably longer than the 6-month check interval, reflecting a service schedule where fluid condition is monitored well before a full drain and refill is required.
