Austin-Healey Sprite

Differential fluid capacity & service interval

Austin-Healey Sprite differential fluid capacity ranges from 0,8 to 0,85 liters. Service intervals include a change or check every 6000 miles or 9600 km. The data covers 5 configurations.

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

Additional Notes

  • The Austin-Healey Sprite rear differential fluid capacity splits into two distinct values across the 1958-1971 production span: 0.85 liter for the MK I, MK II, and MK II 1100, and 0.80 liter for the MK III and MK IV.
  • The 0.05-liter reduction in differential capacity beginning with the MK III (1964-1966) coincides with a change in the service operation type, shifting from a fluid change interval to a fluid check interval at the same mileage threshold.
  • For the Sprite MK I (Frogeye) covering 1958-1961, the rear differential holds 0.85 liter and calls for a full fluid change every 6,000 miles (9,600 km) under normal use conditions.
  • The MK II (1961-1962) and MK II 1100 (1962-1964) share identical rear differential specifications: a 0.85-liter capacity with a change interval of 6,000 miles (9,600 km) under normal use.
  • The MK III (1964-1966) and MK IV (1966-1971) both carry a 0.80-liter rear differential capacity, with the service action at 6,000 miles (9,600 km) specified as a check rather than a drain-and-refill change.
  • A 6,000-mile (9,600 km) interval appears across all five configurations, though the nature of the service at that interval differs between the earlier and later variants, as noted above.
  • The 0.85-liter fill volume on the MK I through MK II 1100 represents a relatively modest differential capacity, consistent with the compact rear axle assemblies found on small British sports cars of the era.
