2019 Duramax Regen
If you have a L5P Duramax Don’t let them do the update for regens, mine used to to 4 to 6 hundred miles between regens, after the recall now 2 to 3 hundard miles

Maybe the truck wastes less fuel doing two quick regens at 250 mile intervals than what it wastes doing one longer regen at 500 miles?
