McCormick X8 Series

AdBlue (DEF) capacity & service interval

McCormick X8 Series tractors utilize AdBlue (DEF) with a capacity range of 64 to 80 liters. Service intervals require a check every 10 hours. The data covers 5 configurations.

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

Additional Notes

  • The McCormick X8 Series AdBlue (DEF) system is paired with a selective catalytic reduction (SCR) setup across all listed configurations, which is the emissions control technology that consumes DEF to reduce nitrogen oxide output from diesel engines.
  • The X8.660 VT-Drive and X8.670 VT-Drive, both covering 2017-2022, share an identical AdBlue tank capacity of 80 liters under normal use conditions.
  • The X8.680 VT-Drive (2017-2022) also carries an 80-liter AdBlue capacity but adds a check interval of every 10 hours, a detail not present in the X8.660 or X8.670 specifications.
  • A 10-hour check interval on the X8.680 VT-Drive reflects a relatively short monitoring cycle, consistent with high-load agricultural operation where DEF consumption rates can be elevated.
  • The Stage V variants, the X8.627 VT-Drive and X8.631 VT-Drive, both starting from 2022, specify a capacity range of 64-80 liters rather than a fixed value, indicating a variable fill window rather than a single defined tank volume.
  • The 64-80 liter range on the Stage V models contrasts with the fixed 80-liter figure on the 2017-2022 models, representing a notable difference in how tank capacity is expressed between the two generations.
  • Stage V is a European emissions standard requiring more stringent exhaust aftertreatment than earlier tiers, which aligns with the SCR notation carried by the X8.627 and X8.631 specifications.
