Austin Montego

Differential fluid capacity & service interval

Austin Montego differential fluid capacity is 0,75 liter. Service intervals are 20000 km or 12 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 Austin Montego differential fluid capacity is 0.75 liter across all listed engine variants and model years, a figure that applies specifically to the differential sourced from the automatic transmission.
  • The 0.75 liter capacity is a service fill value, meaning it reflects the amount of fluid the differential housing holds under normal operating conditions rather than a full overhaul or dry-fill quantity.
  • All four configurations share an identical check interval of 20,000 km or 12 months, whichever comes first, under normal use conditions.
  • The 1.3-liter engine configurations span two consecutive production periods, 1984-1986 and 1986-1990, yet both carry the same 0.75 liter capacity and 20,000 km check interval.
  • The same pattern holds for the 1.6-liter engine, where the 1984-1986 and 1986-1990 variants share identical differential fluid specifications despite representing different production phases.
  • A time-based interval of 12 months runs alongside the distance-based 20,000 km interval, meaning whichever threshold is reached first triggers the fluid check regardless of mileage accumulation.
