Glas 1700

Differential fluid capacity & service interval

Glas 1700 differential fluid capacity ranges from 0,8 to 1,3 liters. Service intervals include 500 km, 3000 km, and 6000 km. The data covers 9 configurations.

Additional Notes

  • The Glas 1700 (1964-1965) rear differential holds 0,8 liter, while the 1700 (1965-1968) and 1700 TS (1965-1968) both hold 1,3 liters, representing a capacity increase of 0,5 liter between the two generations.
  • Across all three configurations, the normal-use rear differential fluid change interval is set at 6000 km.
  • An initial service interval of 500 km applies to all three configurations, meaning the first fluid change occurs very early in the vehicle's service life to remove break-in contaminants from the differential.
  • A second change only interval of 3000 km is specified for all three configurations, placing a single intermediate fluid change between the 500 km initial service and the recurring 6000 km normal interval.
  • The three-stage interval structure — 500 km, 3000 km, then 6000 km recurring — reflects a break-in protocol common to rear differentials of the era, where new gear surfaces shed metal particles during early operation.
  • The 1700 TS (1965-1968) shares the same 1,3-liter rear differential capacity and identical interval schedule as the standard 1700 (1965-1968), indicating no differentiation in differential service requirements between the two trim levels.
