Bone Stock & Fuel Mileage

Considering a Cummins · 10-27-2009, 10:31 AM

I'm looking for some feed back on guys and girls with mainly stock LMM trucks with what kind of actual fuel mileage they are getting with them. Just curious as to who's supposdly getting what kind of mileage with their rigs.

Thanks,

I was getting 14-15 mpg when I was stock, but the truck was not broke in at that point.

Many cummins are having warrenty claims not so duramax.what more matters with a new truck more than no trouble.

20 mpg all highway going 65 mph. 12+ going to work which is 10 stops and about 4 miles, this does not make for great mileage. 11+ towing my 11K gross weight TT. It drops to 9 to 10 when you are driving into a 30 mph headwind in Iowa.

ive been getting about 15-17 driving around and 14 towing about 6k trailer but the truck is not broken in yet so im told it will go up plus its stock and has the dpf.
I went on a trip which was all highway and freeway and drove 65-73 and got 18.5

I have a 2008 crew cab that is 100% stock. I just returned from a 5181.6 mile trip. I had 5000 miles on truck when I started trip. I live in Alabama and trip went through Michigan into Canada. Across Canada to Nova Scotia down through Maine, and most of New England states back home. Total miles 5181.6. Of those miles, 647.5 was site seeing and not towing. 4534.1 was towing 12,040 lbs 5th wheel. Liters converted to gallons added to gallons for total of 441.94 gallons. Figure for yourself 11.72 miles per gallon over all. Some of the grades in New Hampshire's White Mountains were 13%. Not as good as my previous 1999 Cummins but the Dmax has 125 more horse power.
