Additional Notes
- The GMC Savana Passenger GMT610 is represented in two distinct engine configurations within the AdBlue (DEF) system specifications, covering the 2.8 TD DPF from 2016 onward and the 6.6 V8 DPF from 2010-2015.
- The 2.8 TD DPF configuration carries a DEF tank capacity of 20.4 liters, which reflects the total fluid volume the exhaust aftertreatment system reservoir holds at a full fill.
- The 6.6 V8 DPF configuration carries a DEF tank capacity of 20.1 liters under the same exhaust aftertreatment system designation, placing the two engine variants within 0.3 liters of each other in total reservoir volume.
- Both capacity figures represent normal use conditions, meaning the values apply to standard operating circumstances rather than a specialized service scenario such as a first change or severe duty cycle.
- DEF tank capacity at the scale of roughly 20 liters is consistent with full reservoir fills on full-size commercial van platforms, where larger tanks reduce the frequency of fluid replenishment relative to smaller passenger vehicles.
