Case - IH Optum CVT

AdBlue (DEF) capacity & service interval

The Case - IH Optum CVT uses AdBlue (DEF) fluid with a capacity of 96 liters. The data covers 2 configurations.

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

TypeSpecifications
Optum 270 CVT (2016- )
  • Use: Normal
  • Capacity 96 liter
Optum 300 CVT (2016- )
  • Use: Normal
  • Capacity 96 liter

Additional Notes

  • Both the Optum 270 CVT and Optum 300 CVT share an identical AdBlue (DEF) tank capacity of 96 liters, which is a notably large reservoir by agricultural equipment standards and reflects the sustained field operation demands placed on high-horsepower tractors.
  • The 96-liter figure represents the total tank fill capacity for the selective catalytic reduction (SCR) system, which is the emissions control technology that consumes DEF to reduce nitrogen oxide (NOx) emissions in the exhaust stream.
  • Both configurations carry a Normal use condition designation, meaning the 96-liter capacity specification applies under standard operating conditions rather than severe or first-change-only scenarios.
  • The Case IH Optum CVT specifications for both the 270 and 300 variants share the same 96-liter DEF capacity from their 2016 starting year, indicating no differentiation in tank sizing between the two power outputs within the CVT model range.
