Additional Notes

  • The GMC Canyon 2.8 TD DPF carries an AdBlue (DEF) tank capacity of 20.4 liters, which represents a full system fill for the exhaust aftertreatment setup rather than a partial service quantity.
  • A 20.4-liter DEF capacity is on the larger end for a mid-size diesel pickup, reflecting the volume needed to sustain selective catalytic reduction (SCR) function across extended driving intervals before a refill is required.
  • The single capacity figure of 20.4 liters applies uniformly across the 2017-2022 model years of the 2.8 TD DPF configuration, indicating no variation in tank size was introduced during that production span.
  • The specification is designated for normal use conditions, meaning the 20.4-liter figure corresponds to standard operating circumstances rather than a severe-duty or first-fill scenario.
