Mercedes-Benz L (EU)

Transfer case fluid capacity & service interval

Mercedes-Benz L (EU) transfer case fluid capacity ranges from 0,8 to 3,8 liters. Service intervals include checks at 10000 km and 12500 km, with fluid changes at 40000 km and 50000 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 Mercedes-Benz L (EU) L 608 D and LT 608 D share an identical transfer case fluid capacity of 0.8 liter, which is a relatively small fill volume consistent with a compact auxiliary transfer unit rather than a heavy-duty transfer assembly.
  • The L 613 D carries a notably larger transfer case capacity of 3.8 liters, nearly five times the volume of the 608 D variants, reflecting a more substantial transfer unit suited to a higher-payload configuration.
  • Under normal use conditions, the L 608 D and LT 608 D share a fluid check interval of 10,000 km and a change interval of 40,000 km.
  • The L 613 D operates on a longer service schedule under normal use conditions, with a fluid check at 12,500 km and a change interval of 50,000 km, both exceeding the intervals specified for the 608 D variants.
  • All three configurations carry a transferbox designation in the notes, confirming the fluid specifications apply specifically to the transfer case assembly rather than the main gearbox or axle differentials.
  • The difference in check intervals between the 608 D variants at 10,000 km and the L 613 D at 12,500 km represents a 25 percent longer monitoring cycle for the larger-capacity unit under equivalent normal use conditions.
