Daihatsu 850/1000

Differential fluid capacity & service interval

Daihatsu 850/1000 requires 0,6 liter of differential fluid. Service intervals include checking at 10000 km and changing at 40000 km. The data covers 2 configurations.

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

Additional Notes

  • Both the Daihatsu 850 (S/T 70) and the 1000 (S/T 75) share an identical rear differential fluid capacity of 0.6 liter, a figure consistent with the compact final drive units found in small economy vehicles of that era.
  • The 0.6 liter capacity represents a service fill volume, meaning the amount of fluid the differential housing holds during normal operation rather than a full overhaul or disassembly quantity.
  • Under normal use conditions, the rear differential fluid on the 1000 (S/T 75) carries a check interval of every 10,000 km, with a full fluid change specified at 40,000 km.
  • The 850 (S/T 70) follows the same interval structure as the 1000, with a 10,000 km check and a 40,000 km change under normal use conditions.
  • The 40,000 km change interval on both configurations reflects a relatively extended drain period for a rear differential of such small capacity, which is characteristic of sealed or semi-sealed axle designs common in lightweight front-engine, rear-drive vehicles of the 1980s.
  • The 1000 (S/T 75) covers model years 1984-1992, while the 850 (S/T 70) spans 1983-1986, meaning the two configurations overlapped in production between 1984 and 1986 with no difference in differential fluid specifications during that shared period.
