Additional Notes

  • The McCormick X4 F/N/XL AdBlue system is classified as a selective catalytic reduction (SCR) system, which is an exhaust aftertreatment technology that injects diesel exhaust fluid into the exhaust stream to reduce nitrogen oxide emissions.
  • All five variants in the X4 F/N/XL lineup — the X4.080, X4.090, X4.100, X4.110, and X4.120 — share an identical AdBlue tank capacity of 7.5 liters, indicating a uniform SCR tank design across the range despite differences in power output between variants.
  • Each variant is powered by the Deutz TCD2.9 L4 engine, a four-cylinder turbocharged diesel unit, and the 7.5-liter AdBlue capacity applies consistently across all power ratings paired with this engine family.
  • The 7.5-liter capacity figure represents a service fill value, meaning the amount of AdBlue the tank holds during normal operation rather than a dry-fill or overhaul measurement.
  • All rows carry a normal use condition, meaning the 7.5-liter capacity specification applies under standard operating conditions rather than a severe-duty or first-fill scenario.
