Additional Notes

  • The Wolseley 1500 uses a transaxle layout, meaning the manual transmission and final drive share a single housing and a common fluid fill of 2.56 liters across all three marks.
  • A 2.56-liter capacity is consistent across the Mk I, Mk II, and Mk III, indicating no mechanical redesign of the transaxle unit altered its fluid volume between 1957 and 1965.
  • The Mk I and Mk II specifications include an initial service change interval of 800 km, which applies only to the break-in period and carries no check interval, distinguishing it from the recurring normal-use schedule.
  • Under normal use, the Mk I (1957-1960) and Mk II (1960-1961) share identical service intervals: a fluid level check at 1,600 km and a full fluid change at 9,600 km.
  • The Mk III (1961-1965) normal-use intervals differ from the earlier marks, with a check interval of 5,000 km and a change interval of 10,000 km, both considerably longer than those specified for the Mk I and Mk II.
  • The shift from a 9,600 km change interval on the Mk I and Mk II to a 10,000 km interval on the Mk III reflects a modest extension in the fluid change frequency under normal operating conditions.
  • No initial service interval is listed for the Mk III, whereas both the Mk I and Mk II carry an 800 km first-change specification, representing a structural difference in how the service schedules are defined across the model generations.
