Aftertreatment Diesel Particulate Filter (DPF) CAUTION Use of diesel fuel other than ultra low sulfur diesel (ULSD) and engine oils other than EO-O Premium Plus (or VDS-4), will adversely affect performance, efficiency and durability of the aftertreatment DPF system and the engine, to the point where the engine may not run at all. Manufacturer's warranties can also be rendered void due to usage of improper fuel. Unapproved fuel additives (including engine oil) are NOT permitted. Blends of No. 1D and No. 2D grades of ULSD are rec- ommended and allowable for cold weather. The exhaust aftertreatment system virtually eliminates exhaust smoke.
Exhaust vapor (water condensation) may be visible during a cold start. If exhaust smoke is visible during engine start up , this indicates a problem with the exhaust aftertreatment system. Take the vehicle to an authorized MACK Truck dealer immediately. Vehicles equipped with a US2010 emission compliant engine have an exhaust aftertreatment system which includes a selec- tive catalytic reduction (SCR) system and a catalyzed aftertreatment diesel particulate filter (DPF). The aftertreatment DPF takes the place of the standard muffler, and it reduces soot and particulate emissions into the atmosphere.
Soot and other particulate matter are collected by a filter where it is eventually oxidized using a aftertreatment DPF regeneration process. Vehicles equipped with a aftertreatment DPF require the use of EO-O Premium Plus (or VDS-4) specification high perform- ance diesel engine oil and ULSD fuel.
