Additional Notes

  • The rear differential of the Austin A99 Westminster holds 1.84 liters of fluid, a figure that applies equally to both the normal service fill and the initial service change.
  • Under normal use conditions, the rear differential fluid is checked at 1,500 km intervals and changed at 9,000 km intervals.
  • An initial service change is specified at 800 km, a notably shorter interval than the 9,000 km normal change cycle, reflecting the break-in period during which new gear surfaces shed fine metallic particles into the fluid.
