I wont lie, the 7.3 powerstrokes got some great fuel economy. But without a doubt in my mind, overall, the cummins is the best when it comes to fuel economy. The early 12valves, they could break 20mpg without a sweat, the later 12valves got almost as good, and they basically kept it up through all of them, except some with the 6.7/dpf cummins havent gotten the best.

Though, I must say that Ford IDI's are up there. My truck, with 285/75/16 BFG's (stock 235/85/16), 3.54 gears, T 19 4 speed (non overdrive, 4th is direct), has gotten 19.7mpg, and no lower than 15mpg (towing a 4-5K pound boat over mountain pass's).

I've heard a stock VP44 Cummins gets a little better than the common rail because the common rail has multiple injection cycles. My 12 valve gets 17 with the 5 speed and 4.10 rearends.

My grandpa has an 03 D-max with the auto, and I noticed on the mileage thing in the dash his average is 14.7, and he does fit the generalization of "drives like an old grandpa" lol.

ive noticed lately that when ive been really throwing some smoke just showing some buddies my truck's setup, i can go abouit 95 miles on $25 worth of fuel. Thats about 15.6 mpg or so in town. So i wouldnt put it past these 12v to get 19 on the highway with 4.10s like mine.

Any time a Cummins guy thinks he gets good mileage, I have two words for him: ROAD TRIP!

Given a couple weeks' notice I can get some time off and am willing to put it out there for all to see. Even Gale Banks' Cummins Dakota doesn't get the MPG I do.

Yeah, it'll cost a few hundred bucks, but I see the value and don't sweat the cost. To me, crowing rights are priceless.

Yeah, but the average diesel truck owner does not have a single cab short bed with 2WD.......that helps just a little.:

I get 18 city and 20-22 hwy with my DMax, but it IS mostly stock with no lift, bigger tires, etc..... When I tow though, it goes to shiite. Usually drops to 11 mpg when pulling either of my trailers and they are usually loaded to full capacity.......oh well.:shrug:
