AC ACE

Differential fluid capacity & service interval

AC ACE differential fluid capacity is 2 liters. Service intervals include checking at 3000 km and changing at 7500 km. The data covers 2 configurations.

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

Additional Notes

  • The AC Ace Bristol carries a rear differential fluid capacity of 2 liters, which represents a service fill volume typical of a compact rear axle housing in a lightweight sports car of that era.
  • The limited slip variant of the rear differential in the Ace Bristol (1956-1963) shares the same 2-liter capacity as the standard open differential, meaning the housing volume does not differ between the two axle configurations.
  • Under normal use conditions, the rear differential fluid on the Ace Bristol is subject to a check interval of 3,000 km, reflecting a relatively short inspection cycle consistent with maintenance practices common to performance-oriented vehicles of the period.
  • The change interval for both the standard and limited slip rear differential is set at 7,500 km under normal use conditions, after which the fluid is due for a full drain and refill to the 2-liter capacity.
