Aro 24

Differential fluid capacity & service interval

Aro 24 uses differential fluid with a capacity range of 1 to 1,7 liters. Service intervals occur every 30000 km or 36 months. The data covers 10 configurations.

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

Additional Notes

  • The Aro 24 carries a front differential fluid capacity of 1 liter across all listed engine variants, including the 2.5, 2.5 D, 2.5 TD, 2.7 D, and 3.1 D.
  • The rear differential holds 1.7 liters across every engine variant in the specifications, which is 70% more fluid volume than the front differential on the same vehicle.
  • The difference in capacity between the front and rear differentials reflects a common engineering pattern in four-wheel-drive vehicles, where the rear axle housing is typically larger and carries a greater fluid volume to support higher torque loads.
  • All listed configurations share an identical service interval of 30,000 km or 36 months under normal use conditions, whichever comes first.
  • The 36-month time limit means a fluid change is due after three years even when the distance threshold has not been reached, which is relevant for low-mileage usage patterns.
  • The 2.5 D variant has the earliest start year among the specifications, with coverage beginning in 1980, while the 2.5 TD is the latest to appear, with coverage starting in 1993.
  • Despite spanning different displacement sizes and induction types, the 2.5, 2.5 D, 2.7 D, and 3.1 D variants all share a common production start year of either 1980 or 1984, indicating the differential housing specifications were consistent across a broad range of powertrain generations.
