Austin-Healey 3000

Differential fluid capacity & service interval

Austin-Healey 3000 requires 1,7 liters of differential fluid. Service intervals occur every 6000 miles or 9600 km. The data covers 3 configurations.

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

Additional Notes

  • The Austin-Healey 3000 rear differential holds 1.7 liters of fluid across all three mark variants produced from 1959-1968.
  • A 1.7-liter differential capacity falls within the typical range for a rear-wheel-drive sports car of the era, reflecting a compact but conventional hypoid gear unit.
  • The MK I (1959-1961), MK II (1961-1963), and MK III (1963-1968) all share an identical 1.7-liter service fill capacity, indicating no mechanical redesign of the differential housing occurred across the production run.
  • The specified change interval for all three variants is 6,000 miles or 9,600 km, which is a relatively short interval by modern standards and reflects the maintenance expectations common to British sports cars of the period.
  • The 6,000-mile change interval applies under normal use conditions for every mark variant, meaning no separate severe-use interval is listed for any configuration.
  • Because the capacity figure represents a service fill rather than an overhaul fill, the 1.7 liters reflects the working fluid volume in a fully assembled and installed differential, not the total system volume during a bench rebuild.
