Glas Isar

Differential fluid capacity & service interval

Glas Isar differential fluid capacity is 0,8 liter. Service intervals include checks at 2500 km and 6000 km, with fluid changes at 10000 km and 24000 km. The data covers 2 configurations.

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

TypeSpecifications
  • Isar T600 (1958-1965)

  • Capacity 0,8 liter
  • Check 2500 km
  • Change 10000 km
  • Isar T700 (1958-1965)
  • Rear
  • Use: Normal
  • Capacity 0,8 liter
  • Check 6000 km
  • Change 24000 km

Additional Notes

  • The Glas Isar T600 and T700 share an identical rear differential fluid capacity of 0.8 liter, which represents the service fill volume used during routine fluid changes rather than a full overhaul measurement.
  • Under normal use conditions, the T600 calls for a differential fluid check interval of 2,500 km, while the T700 specifies a notably longer check interval of 6,000 km, reflecting a meaningful difference between the two variants despite their shared capacity figure.
  • The fluid change interval separates the two variants considerably. The T600 requires a change at 10,000 km under normal use, whereas the T700 extends that interval to 24,000 km, also under normal use conditions.
  • Both the T600 and T700 cover the model years 1958-1965, yet their differential service schedules diverge substantially, with the T700 operating on intervals roughly 2.4 times longer than those of the T600 for both the check and change milestones.
