I was just curious as to how much fuel the Duramax uses idling. Does anyone know a gallon per hour figure?

fool32696 07-19-2005, 11:12 PM Does anyone know about idling fuel consumption? GMC2500HD 07-19-2005, 11:28 PM I would venture to say the craziest thing, but very little.... I think you might be able to get that information from a diesel tech... I really don't let my truck idle that long unless absolutely necessary... aka108 07-20-2005, 10:42 AM Supposedly not too much but I see no purpose in wasting fuel since no matter how little it may use you are getting 0 mpg for that time. lakingslayer 07-20-2005, 11:51 AM If my memory serves me correctly someone posted a while back it was about .75gal/hr. coalbucket1 07-20-2005, 12:39 PM .5-.75 gph depending on acc. load.
