Valtra (Valmet) A5 Series

AdBlue (DEF) capacity & service interval

The Valtra A5 Series uses AdBlue (DEF) fluid with a capacity of 13 liters. The data covers 7 configurations of the model.

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

Additional Notes

  • All seven variants in the Valtra (Valmet) A5 Series — the A75, A85, A95, A105, A115, A125, and A135 — share an identical AdBlue (DEF) tank capacity of 13 liters, indicating a common reservoir design across the entire model range from 2020 onward.
  • The 13-liter figure represents the total fluid capacity of the AdBlue tank, meaning the full volume available for the diesel exhaust fluid used in the selective catalytic reduction (SCR) system to reduce nitrogen oxide (NOx) emissions.
  • Selective catalytic reduction is an emissions control technology that injects AdBlue, a urea-water solution, into the exhaust stream. The 13-liter tank capacity on each A5 Series variant determines how frequently refilling is required relative to fuel consumption and engine load.
  • The capacity specifications for all seven A5 Series models are listed under normal use conditions, meaning the 13-liter figure applies to standard operating circumstances rather than severe-duty or other modified service conditions.
  • No variation in AdBlue tank capacity exists across the A5 Series power range, from the lower-output A75 to the higher-output A135, despite the differences in engine displacement or power output that typically influence exhaust fluid consumption rates.
