Additional Notes

  • The Chevrolet Express / Van GMT610 (USA / CAN) AdBlue system on the 2.8 TD DPF carries a capacity of 20.4 liters, which reflects a full tank fill for the exhaust aftertreatment system rather than a minor top-up quantity.
  • The 6.6 V8 DPF configuration, covering 2010-2015, holds a slightly smaller AdBlue capacity of 20.1 liters compared to the 20.4 liters specified for the 2.8 TD DPF.
  • Both configurations list a normal use condition, meaning the stated capacities apply to standard operating environments rather than severe-duty or first-change-only scenarios.
  • The 0.3-liter difference between the two engine configurations indicates that tank volume is not uniform across the Express lineup and varies by powertrain generation.
  • AdBlue, also known as Diesel Exhaust Fluid, is a urea-water solution injected into the exhaust stream to reduce nitrogen oxide emissions, and a 20-liter-class tank is consistent with commercial van applications where extended range between refills is a practical consideration.
