Even the D13F's CF is running with the tiny daycabs arnt getting those numbers. But again lots of EGR and now catalysed DPF hurts mileage too. Ive heard some of the old detroits would get around 11 but then your getting pretty old then. One of the old V92's I think or an early 60 series.

most of the people running them are using volvo 630's 770's ect. they are all reporting 12 as an average empty. my buddy has a KW (comercial driver) and he is getting 12.5 bobtailing in the mountains.
8 bobtailing most guys I talk to are getting that hauling 60K + lbs. I was talking to a couple last night when I went to have coffee with my buddy and they said if they had a truck that got 8 empty they would return it as theres something wrong with it and they have never seen a truck get under 11 bobtailing unless there was something wrong or the driver was an idiot.
