MG Magnette

Differential fluid capacity & service interval

MG Magnette differential fluid capacity ranges from 1,28 to 1,56 liters. Service intervals include checks at 1600 km and 10000 km, and changes at 800 km and 9600 km. The data covers 7 configurations.

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

Additional Notes

  • The MG Magnette ZA (1953-1956), ZB (1956-1958), and Mk IV (1961-1969) all share a rear differential fluid capacity of 1.56 liters, while the Mk III (1959-1961) holds a notably smaller 1.28 liters.
  • The Mk III rear differential capacity of 1.28 liters represents the lowest fill volume across all Magnette variants in the specifications, reflecting a physically smaller differential unit compared to the 1.56-liter units found in the other variants.
  • For the Magnette ZA, ZB, and Mk III, an initial service fluid change is specified at 800 km. An early drain interval of this kind is standard practice for breaking in gear components, as metal particles shed during initial wear are removed before the regular service schedule begins.
  • Under normal use conditions, the ZA, ZB, and Mk III all share a check interval of 1,600 km and a change interval of 9,600 km for the rear differential fluid.
  • The Mk IV rear differential specifies only a check interval of 10,000 km under normal use conditions, with no fluid change interval listed alongside it, distinguishing the Mk IV service schedule from the earlier ZA, ZB, and Mk III specifications.
  • The Mk IV check interval of 10,000 km is notably longer than the 1,600 km check interval shared by the ZA, ZB, and Mk III, indicating a less frequent inspection requirement for the Mk IV rear differential under normal use.
  • No initial service interval is listed for the Mk IV rear differential, whereas the ZA, ZB, and Mk III each carry an 800 km initial service change specification.
