ERF EC6

Manual transmission fluid capacity & service interval

ERF EC6 manual transmission fluid capacity ranges from 7,5 to 8,5 liters. Service intervals include checks at 16000 km and changes at 100000 km or 6 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 ERF EC6 manual transmission fluid capacity varies by configuration, with the EC 6.22 listing two distinct values: 7.5 liters and 8.5 liters, reflecting different gearbox units fitted to the same drivetrain layout.
  • The EC 6.23 (4x2/6x2) carries a single manual transmission fluid capacity of 8.5 liters, which aligns with the higher of the two capacities listed for the EC 6.22.
  • A check interval of 16,000 km applies uniformly across all three rows, indicating a recurring inspection point well ahead of the full drain cycle.
  • The change interval across all configurations is set at 100,000 km or 6 months, whichever comes first, meaning time elapsed can trigger a fluid change independently of distance traveled.
  • All three rows are designated for normal use conditions, meaning the 100,000 km/6-month change interval is not a reduced severe-duty schedule but the standard operating baseline.
  • The 4x2 and 6x2 axle configurations share identical fluid capacities and service intervals within each engine variant, indicating no differentiation in transmission servicing requirements between those two drivetrain layouts.
