Valtra (Valmet) S6 Series

AdBlue (DEF) capacity & service interval

The Valtra S6 Series uses AdBlue (DEF) fluid with a capacity of 72 liters. The data covers 6 configurations of the model.

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

Additional Notes

  • All six Valtra (Valmet) S6 Series variants — the S286, S316, S346, S376, S396, and S416 — share an identical AdBlue (DEF) tank capacity of 72 liters across the entire lineup starting from 2023.
  • A 72-liter AdBlue reservoir is a notably large capacity for agricultural machinery, reflecting the high-output engine demands of tractors in this power class and reducing the frequency of fluid top-ups during extended field operations.
  • AdBlue, also known as Diesel Exhaust Fluid (DEF), is a urea-water solution consumed by the selective catalytic reduction (SCR) system to convert nitrogen oxides (NOx) in exhaust gases into harmless nitrogen and water vapor, in compliance with emissions regulations.
  • The SCR system noted across all S6 Series configurations operates independently of the engine oil or fuel circuits, meaning the 72-liter figure represents the dedicated AdBlue tank volume rather than any shared or combined fluid reservoir.
  • The uniform 72-liter capacity across the S286 through S416 variants indicates that despite differences in engine output between models, the AdBlue tank architecture was standardized across the S6 Series platform from 2023 onward.
