BMC Austin/Morris 250 JU

Power steering fluid capacity & service interval

BMC Austin/Morris 250 JU uses power steering fluid with a capacity range of 0,43 to 0,5 liters. Service intervals require checks every 10000 km or 6 months. The data covers 4 configurations.

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

Additional Notes

  • The BMC Austin/Morris 250 JU carries a steering box rather than a rack-and-pinion assembly, which is reflected in the relatively small fluid capacities listed across all four configurations.
  • Both the petrol and diesel variants built between 1967-1971 share an identical steering box capacity of 0.43 liter under normal use conditions.
  • A capacity increase to 0.5 liter applies to both the petrol and diesel variants produced in the 1971-1974 period, representing a modest but consistent rise across engine types from the earlier generation.
  • The 0.07-liter difference between the 1967-1971 and 1971-1974 configurations suggests a revised or enlarged steering box unit was introduced at the 1971 production change, affecting both petrol and diesel variants equally.
  • All four configurations share the same service interval: a fluid check every 10,000 km or every 6 months, whichever comes first, under normal use conditions.
  • The dual-trigger interval structure, combining a distance threshold with a time-based threshold, means a vehicle covering low annual mileage would still reach a service point at the 6-month mark before accumulating 10,000 km.
  • No variation in service interval exists between the petrol and diesel variants at any model year, as all rows specify the same 10,000 km or 6-month check schedule under normal conditions.
