Daihatsu Sirion

Differential fluid capacity & service interval

Daihatsu Sirion differential fluid capacity is 1 liter. Service intervals include 25000 km, 40000 km, or 48 months. The data covers 3 configurations.

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

Additional Notes

  • The Daihatsu Sirion rear differential holds exactly 1 liter of fluid across all listed 4x4 configurations, a figure consistent with the compact final drive units found in small-displacement all-wheel-drive vehicles of this era.
  • The 1-liter capacity appears uniform between the 1.0 12V and 1.3 16V engine variants, indicating no meaningful difference in rear differential size between the two powertrains despite the displacement gap.
  • Under normal use conditions, the 1.0 12V 4x4 rear differential fluid change interval is set at 40,000 km or 48 months, whichever comes first, meaning both a distance and a time limit govern the service cycle simultaneously.
  • Under severe use conditions, the same 1.0 12V 4x4 rear differential carries only a distance-based interval of 25,000 km, with no time-based limit listed alongside it, reducing the change interval by 15,000 km compared to normal use.
  • The 1.3 16V 4x4, available from 2000-2005, shares the identical normal-use interval of 40,000 km or 48 months with the 1.0 12V 4x4, despite entering production one year later within the same generation.
