MG MGA

Differential fluid capacity & service interval

MG MGA differential fluid capacity is 1,3 liter. Service intervals include checking at 5000 km and changing at 10000 km. The data covers 4 configurations.

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

Additional Notes

  • The MG MGA rear differential holds 1.3 liters of fluid across all four configurations covered in the 1955-1962 production span, including the 1500, 1600, 1600 Mk. II, and Twin Cam variants.
  • A 1.3-liter differential capacity is a relatively modest fill volume, consistent with the compact rear axle assemblies typical of British sports cars from the period.
  • The check interval for the rear differential is set at 5,000 km under normal use conditions, meaning fluid level inspections are scheduled at twice the frequency of full fluid changes.
  • The change interval is 10,000 km under normal use conditions, applying uniformly to the 1500, 1600, 1600 Mk. II, and Twin Cam configurations without variation.
  • The MGA 1500 (1955-1959) and the later 1600-series models share identical differential service intervals and capacity figures, indicating no revision to rear axle servicing requirements between the earlier and later engine displacements.
  • The MGA Twin Cam, which used a distinct twin-camshaft engine compared to the pushrod units in the other variants, carries the same 1.3-liter rear differential capacity and 10,000 km change interval, reflecting a shared rear axle specification rather than a drivetrain-specific service schedule.
