Volvo FL-6 Euro 3 (EU)

Manual transmission fluid capacity & service interval

Volvo FL-6 Euro 3 (EU) manual transmission fluid capacity ranges from 7,5 to 9,5 liters. Service intervals consist of 60000 km or 6 months and 120000 km or 12 months. The data covers 12 configurations.

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

Additional Notes

  • The Volvo FL-6 Euro 3 manual transmission fluid specifications list two distinct capacity values across all variants: 7.5 liters and 9.5 liters. The difference of 2 liters between the two figures reflects different transmission unit sizes fitted to the same engine variants rather than a difference in service type.
  • The 9.5-liter capacity represents a notably larger transmission fill volume, which is consistent with heavier-duty gearbox assemblies used in commercial truck applications where torque handling requirements are greater.
  • All three power variants covered by the specifications — the FL 6-180, FL 6-220, and FL 6-250 Euro 3 — share identical capacity values of 7.5 liters and 9.5 liters, meaning the rated engine output does not alter the transmission fluid volume requirement across the 2001-2006 range.
  • Under normal use conditions, the manual transmission fluid change interval across all FL-6 Euro 3 variants is 120,000 km or 12 months, whichever comes first. The dual-trigger format means a time-based change is required even when the distance threshold has not been reached.
  • Under severe use conditions, the change interval is reduced to 60,000 km or 6 months for all FL-6 Euro 3 variants regardless of capacity. Severe use effectively halves both the distance and time thresholds compared to normal use intervals.
  • The 60,000 km severe-use interval applies equally to both the 7.5-liter and 9.5-liter transmission configurations, indicating that the use condition classification governs the service schedule independently of the transmission size.
  • The consistent interval structure across the FL 6-180, FL 6-220, and FL 6-250 for the full 2001-2006 model year span means service planning for mixed fleets of these variants can follow a single interval framework, differentiated only by use condition and transmission capacity.
