Additional Notes

  • The Ram Trucks ProMaster VF carries an AdBlue (DEF) tank capacity of 18.9 liters across both the 2013-2014 and 2014-2018 3.0-liter configurations, placing it in a range typical of light commercial diesel vehicles where a larger reservoir reduces the frequency of refills between service visits.
  • Both configurations share the same 18.9-liter capacity figure under normal use conditions, meaning the specification applies to standard operating cycles rather than severe-duty or first-fill scenarios.
  • The 3.0-liter engine in the ProMaster VF is paired with a selective catalytic reduction system, which is the emissions control architecture that consumes the DEF fluid stored in the 18.9-liter tank to reduce nitrogen oxide output in the exhaust stream.
  • The 2013-2014 and 2014-2018 row entries overlap at the 2014 model year, indicating that the 18.9-liter capacity figure applies to 3.0-liter ProMaster VF units produced across the full 2013-2018 span without interruption in that specification.
