i was wondering what was the best mileage you can possibly get out of a diesel

with a chip possibly.

My LB7 Duramax gets about 21-22 mpg unloaded at 65-70 mph. Loaded with a 7x18 and about 4k or so on the trailer, at the same speed get about 15-16 mpg. Not too bad.

04 D-max (dads)with a utility body full of tools and a crane about 10k all the time runs about 18. A friend who owns a mobile repair business has a 7.3 ford p-stroke gets about 14 and his 6.0p-stroke gets about 12-13 both run loaded all the time.

04.5 Cummins just logged 18.5mpg in CITY driving...best it has ever gotten in the city. Was on #1 diesel with powerservices' diesel kleen. Usually city driving gets it around 16.5-17.5. On the highway it'll get from 20-22 running 75. These numbers are unloaded. Throw 12k behind it and your talking 11-12. Auto trans; 40k miles.

My 96 Powerstroke has gotten, on 2 occasions 21 mpg, highway miles, no trailer (I'm thinkin my last scale ticket said the truck weighed close to 7k, not sure though). I cut out my cat and muffler a long time ago, and have the edge evolution set on #2 race, running an additive called "freedom fuel" that i buy from my cousin, not sure who they get it from. I can usually count on about 16 in town pullin 16' open w/ 737 Z-trak, 36 and 48 w/b's, 21", trimmers, blowers, etc. On the highway empty I am more accustom to like 17-18.5. Truck has 171K, 5 speed 4:11 or 4:10's, whatever the low gears are. If you are looking for fuel mileage, then Cummins is the way to go, don't have any for sure numbers but I know that I can go further on $40 worth of diesel in my bosses 99 cummins dually than in my 'stroke.

why are you excluding the duromax?

sorry, thought about that right after I posted. The only experience I have had with them is the one that a guy we work every once in a while has. It is a 06 with 15K, no mods. I can't quite remember for sure what he said his mileage was, but I think he said it was somewhere in the 16-18 highway empty, I don't think he's really checked it with the trailers yet, about the same as my 'stroke. It is a 06 D-max 3500 dually extended cab. I am just around the cummins and obviously my PSD a lot more, sorry to leave one out.

I don't know why mileage is such an issue, most of these trucks are only 6 MPG's apart, who cares? You should be charging enough to cover fuel prices. If you want a personal vehicle that gets good mileage, buy a car. These mileage fights are stupid and pointless.

The last time I checked my fuel milage on my 1991 3/4 Ton Dodge diesel. I got 20.89 with my foot in it. This is highway miles. I have got almost 22 highway. I have also got 16 to 17 in town pulling a load. Later, Tony

All cummins all the time.

Ignorant? No. I'm realistic. There's no getting around the gas prices, why cry about it? Like I said, if you've built fuel prices into your bids and contracts, it wouldn't be an issue and unless you drive you work rig around off the clock, it shouldn't affect you. I guess maybe this thread is more for "comparison" sake, but I've seen some ridiculous arguments that get down to Chevy vs. Ford over mileage. Now that, my friends, is ignorance. In some cases, I've heard of guys buying lighter duty trucks just because of gas prices which is stupid as well. My philosophy about mileage is this: I need the work truck I drive and mileage is what it is. As long as I'm not burning countless gallons that I'm not charging for, what is there to complain about? Sorry if my last post made me sound like an @$$, I re-read it and it came out a little wrong, but my overall point is that it's not worth switching brands, size, or upfitting of trucks to save a few dollars.

Duramax mileage for us, all in all has been somewhat disappointing, 4 kodiaks, 5 one tons, and the pickups.Some of the trucks get excellent mileage, some a truck burning piss could get better.

who cares

I would rather care about passing power.

Like pulling the hills in North Carolina at 75mph up the interstate passing all the little 1/2 & 3/4 tons with their bumper draggers.

We were pulling about 14,000lbs give or take in a 1 ton diesel and never saw worse than 8mpg.

My old 95 cummins 3/4 ton 5 spd. got 22-23 mpg empty highway, and i got 24 mpg once with the cruise set. It got 16-18 around town with 12k dump trailer loaded. It had a banks stinger plus kit, huge cone k&n air intake, 4" exhaust, and some fuel plate work. I wish the new 6.0 powerstroke would get half that mileage.

So much info, so little time!!!!

First of all lets remember that the truck that holds the land speed record is a Dodge Dakota outfitted with a Cummins 5.9 ltr. H.O. (Banks.com)

Second speed is a fuel thief. The recommended speed for a diesel truck to obtain maximum fuel efficacy is 60-65 mph. At that speed empty my '03 2500 single axle, 4x4, with modifications is 20.5-21.5. That is of course on flat ground, and by using a calculator to figure it out after fueling. Most of our trucks have those computers overhead that tell us the fuel mlg., but they are not very accurate.

Does a 6 cylinder car get better fuel mileage than a V8?

As far as chipping goes, wait. If you chip it, you will be making modifications to your fuel system to increase things, and the rest of the truck will not be up to speed. Something will break. I would modify your air flow in, and out of your truck first, add an after-market double deep tranny pan, and a pyro., tranny, and boost gage to it before chipping it. Yes, Dodge has had its share of Transmission trouble, but if your going to buy used look for an '03.5-'04, or the '06. These trucks are out fitted with the 48-RE Transmission their best one yet.

I cant count how many Ford people I know have, going to, or wish they could switch to Dodge.

I also know quite a few unhappy Chevy owners, and two of them are switching to Dodge.

After all that if you are still considering a Ford or a Chevy click on this web site first.

My dad and I had a 95 & 96 Ford F250 PS Auto 2wd 3.55 gears, get 23 hwy running 80. My dad took his truck from SW Miss to Central WA state, left wed noon, got there 7pm fri...2650 miles...avg 22.7mpg, hauling A$$.
We bought two used F450, PS 5speed with 5.23 (i think), Keith Huber Princess pumper units(portacrapper trucks) pulled one with the other on a two wheel tow dolly, ran 75 or better from PA to MS, got 11 mpg and came out of 5th gear 5 times due to hills!
Dad has a new F250 auto 3.73, getting 20 mpg empty, and he rarely gets under 80 on the highway, I think he still thinks he is a kid.....at 63.
We had a guy working for us, had the old body style dodge, (early 90's?) cummins diesel, 5 speed, would drive out to cali once a year pulling a 35' bumper pull camper, running the speed limit, would get 21mpg, until a recall put a bigger fuel pump on it and his mileage went down to 19mpg.
Im ready for someone to bring a small turbo diesel pickup out, like Nissan or Toyota.

No one is gonna believe this, but i just have to share cuz i am in so much shock and so excited. I fuel up at the same place, same pump, every time. Let the pump go till it shuts off, and that is that. I filled up both tanks on the 'stroke on Friday afternoon, drove 315 miles between then and this morning, put in 12.14 gallons of fuel between the two tanks, both pegged the needle, so they are at least really close to being full. By these numbers, i am over 25 mpg, and i figgered this 4 different times cuz i didnt believe it. I was empty all weekend, which i know now for sure that "empty" w/ my toolbox and L-tank is 7K+ lbs, but drivin it like i stole it friday night (had to show a rice grinder or two what was up). And pulled the trailer bout 85 miles round trip yesterday, loaded w/ lumber on the return side. I need to figger out what i did right, but i just had to tell someone!:drinkup:

I've got a 2005 Dodge 2500 Quad Cab w/ the 5.9 diesel, auto, 4x4 & about 23K on it. No Mods yet - still under warranty & don't want to take chances. I have seen on several occasions 24 HWY miles when making road trips. Towing the mower trailer around town, I average 12 - 13 & w/ the Case 1845C & trailer, I average 10.5 - 12.

agreed except my dad has the same truck ext. cab. 2wd and all stock. with a 5spd no cruise. so its been said and i'll say it again dodge with there 6cyl turbo diesel get the best fuel mileage and the most ft.lbs. per liter.

I always get a laugh out of mileage topics. Im on my second diesel had a 00 7.3 now i have 03 6.0 Both gets me around 15 around town pulling cat and hydro seeder 13. On the road i got 20. I always heard everyone else gets 20-22 all the time. I really wonder if everyone knows how to figure mileage it always seems funny all of my bodys get this great mil. but me. Yes i have a chip in mine because my 6.0 is a piece of **** and would not pull out with a load. I put a chip in on the tow mode and now it runs like a 7.3 never did anything for the mil.

Tell me about your d-max. I pull bobcat and hydro seeder around. i now have a 03 f-350 srw 6.0 Im looking to buy a new truck this year.

Its all about the LBZ Duramax:weightlifter: , its such a great engine, Pulls a Kubota KX 121 without a problem and unloaded I can roast anything on the road (ya, its a dump truck:hammerhead: ) Hoping to take it to the track sometime this summer and see what the QT is before I chip it:dizzy: .
Thanks
