Additional Notes
- The GMC Savana GMT610 AdBlue (DEF) system appears across two distinct engine configurations, each with its own tank capacity specification tied to normal use conditions.
- The Savana 2.8 TD DPF, covering model years 2016-2023, carries a DEF tank capacity of 20.4 liters, which represents the total fluid volume the reservoir holds for exhaust aftertreatment operation under normal use.
- The Savana 6.6 V8 DPF, covering model years 2010-2015, carries a DEF tank capacity of 20.1 liters under the same normal use condition, placing the two configurations within 0.3 liters of each other despite differing engine architectures.
- Both capacity figures reflect service fill volumes for the exhaust aftertreatment system, meaning the amount of DEF the tank accepts during a standard refill rather than a component overhaul or dry-fill scenario.
- DEF, also known as AdBlue in European and international markets, is a urea-water solution consumed by selective catalytic reduction (SCR) systems to reduce nitrogen oxide emissions in diesel engines, which explains the presence of a dedicated tank capacity specification separate from engine oil or coolant.
- The 2.8 TD DPF and 6.6 V8 DPF designations both include a diesel particulate filter (DPF) alongside the SCR system, indicating a two-stage exhaust aftertreatment setup where DEF consumption is a routine part of normal operation.
