Wartburg 311

Manual transmission fluid capacity & service interval

Wartburg 311 manual transmission fluid capacity ranges from 2,25 to 2,5 liters. Service intervals include checking at 5000 km and changing at 10000 km. The data covers 3 configurations.

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

Additional Notes

  • The Wartburg 311 transaxle carries a service fill capacity of 2.25 liters, which represents the amount of fluid used during a routine drain-and-refill procedure on an already-assembled unit.
  • A separate dry fill capacity of 2.5 liters applies when the transaxle is filled from a completely empty state, such as after a full overhaul or replacement, accounting for the additional fluid needed to prime internal passages and cavities.
  • The 0.25-liter difference between the service fill and dry fill figures is consistent with the residual fluid that remains in a transaxle after draining, meaning a dry assembly requires that extra volume to reach the correct operating level.
  • A fluid check interval of 5,000 km is specified under normal use conditions, indicating a mid-cycle inspection point rather than a full fluid exchange.
  • The fluid change interval is set at 10,000 km under normal use conditions, placing the full drain-and-refill at twice the frequency of the check interval.
  • The 311 Standard and 311 Sport-CoupĂ©, both covering model years 1956-1961, share identical transaxle fluid capacities and service intervals with the later 311 produced from 1962-1965, indicating no revision to these specifications across the production span covered.
