Mercedes-Benz S-Class, W140 / V140 / C140 (EU)

Manual transmission fluid capacity & service interval

Mercedes-Benz S-Class, W140 / V140 / C140 (EU) manual transmission fluid capacity is 1,5 liters. Service intervals include checks at 20000 km and 25000 km. The data covers 2 configurations.

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

TypeSpecifications
300 SE 2.8, S 280 (1993-1998)
  • Use: Normal
  • Capacity 1,5 liter
  • Check 25000 km
  • Code: 5/1
300 SE, SEL (1991-1994)
  • Use: Normal
  • Capacity 1,5 liter
  • Check 20000 km
  • Code: 5/1

Additional Notes

  • The manual transmission fluid capacity across both configurations is 1.5 liters, a figure consistent with a service fill rather than a full overhaul quantity, as overhaul fills typically account for additional fluid retained in disassembled components.
  • The 300 SE 2.8 and S 280, covering model years 1993-1998, carries a fluid check interval of 25,000 km under normal use conditions.
  • The 300 SE and SEL, covering model years 1991-1994, carries a fluid check interval of 20,000 km under normal use conditions, which is 5,000 km shorter than the interval specified for the later 300 SE 2.8 and S 280 variants.
  • The Mercedes-Benz S-Class W140 manual transmission fluid capacity of 1.5 liters is relatively modest, reflecting the compact internal volume typical of passenger car manual gearboxes in this segment.
  • Both configurations share identical fluid capacity despite differing in engine designation and model year span, indicating the same transmission unit was likely carried across the 300 SE lineage into the S 280 generation.
