    This is for all you Diesel pick-up truck drivers. I am in the market for a new pickup. I have heard different conflicting stories about how many miles per gallon a diesel gets versus a conventional gas engine. My question is two-fold.

    1. What type of pick-up do you drive? F-250, etc.

    2. How many miles do you get in City, Highway, and Hauling if you pull a travel type trailer.

    I currently have a F-150 and get 11.5 miles per gallon, but have heard that diesels are getting upwards of 22. I would like to get a straight answer.

    Thanks for all your help.

    2001, F 250 PSD, 2WD, super cab, 8' bed, tool chest forward, loaded for shooting, 17MPG around town, 22 MPG on highways at 61MPH matching the 18 wheelers and most of the highway travel is over western mountain areas. Previously towed a 30', 9000 lb 5th wheel, same speed, that seemed to keep me in the neighborhood of 12MPG, over the same mountains....breakemall....Bob Dodd

    Cory - You are going to get a lot of conflicting information. I have a Chevy
    Duramax (2006). Mileage on the highway (2,000 miles from CA to Colorado and back) 19.2. One of my person friends with a 2006 For F250 diesel. Same trip. (18.1). I drove average 78 mph, he drove 70. Another friend has a Dodge. His milage about 18 highway. My towing mileage with a 7,000 5th wheel is slightly over 14. I drive average 65mph. Hope the information is helpful. - Jim

    But, factor in the possibility that good friend Jim and his buddies no doubt are driving 4WD - I'm not!....Bob Dodd

    Our shop truck is a 2000 F-350 Crew AT Lariet it has gotten 15.2 city and that includes alot of moving trailers around the log. My best milage was 26.2 but the empty average is more like 24. Towing a 5000 lb travel trailer it ususally gets 22 and with a 7500 lb 5th wheel it averages 18mpg even in the wind here in Montana. Not bad for a truck that weighs close to 8000lbs wet.It is a 4wd.
    Go Well

    I put over 100,000 miles on a 1999 F350. Pulling a 6000 lb trailer hwy milage was 10 at best. No trailer empty 16 maybe, pulling a dual axle trailer around town with lawn mowers 12 at best. I currently have a 2005 dodge with cummings 373 gear and except for the lawn trailer the milage is the same. Lawn trailer will sometimes be 14 but most 12.9. I do paper milage and it is never what the computer shows, wish it were. My nephew has a Duramax all chipped out and gets good milage under 65 and empty. As soon as he puts the smallest trailer behind it the milage goes south. Maybe you could rent one for a weekend and see for yourself what the real deal is. Jake

    I drive a 05 gmc duramax, I have a programmer installed, I have gotten 26.5 mpg on the interstate doing 65 empty (best ever). Usually runs about 24, in town is usually 17 to 22....got 20.5 hauling a dodge dually on the interstate, with my goose neck trailer...but this changes with different typs of fuel, it seems to always do best if there is a high mix of biodiesel. and I also use Stanadyne in the fuel.

    Also I have heard that the newer models donot get as good mileage because of the emissions, and regeneration systems.

    check out dieselplace.com.....there is alot of info there that you can search about anything you want on diesels....they are the only way to go!

    I drive a diesel 06 Ford F-350 crew cab 4x4 with SRW. It has the long bed to boot. Driving in heavy traffic the truck gets 15 MPG, on the highway driving 80+ ( I am always in a hurry) about 17MPG and towing a 35' 12,000 lb fifth wheel it gets 11-12. The only real draw back to this beast is it takes about 40 acres to do a u-turn. ( without the trailer ) I had 2 Dodges with the Cummins. I put a Banks kit in one, but neither could pull like this Ford does.

    Good luck,
    Mark

    03 Dodge 3500 dual wheel 2 wheel drive king cab. 18 to 19 around town and 16 to 17 on the highway just above 70 most of the time.. The thing is geared low to pull and overrevs on the highway. Better mileage can be had with a 2 wheel drive 3/4 ton geared high with a good overdrive tranny - or so I am told. I have never heard about more than 23 to 25. Oh - I get 11 with a 10,000 lb trailer.


    If you need something to do work expect below 20. If you just need the bed sometimes then go light and gear high. Leave the tailgate off and use a net on the rear.

    Another thing is if you have an on board info center that reads MPG, miles to empty, fuel used blah blah......those are standardly off by about 4-10%. The only way to get true milage is by an actual gas log. Miles at fill up - miles since last fill divided by gallons = true MPG.
    I ran diesels for a while and the best was about 23mpg with a duramax chevy with an empty load, other wise it wasnt anything to write home about. Now I just own gassers since I do not tow any longer which is what they are best for not miles per gallons.
    Now I run a 2007 Chevy CC 4x4 with the 4.8 motor and get 14-16 mpg in town and average 21-22 on the freeway empty at 73 mph, no towing. Heavy loads (600lbs) on a trip right at 19 mpg, cruise on at 70 mph.

    Wouldn't a two speed differential come in handy for loads and empty? That would be a real winner with diesel pickups. Hap

    My 2006 Dodge gets 20 (GPS miles / actual fuel pumped) as long as I stay under 68 mph. That's with the 3.73 rear end and one size larger tires, 4x4, 4 door long bed. With a 12,000 lb trailer and a ton in the bed, about 11. No mods, about 90,000 miles on the odometer.

    Above 68 mph it's like hitting a brick wall. She starts sucking down fuel; at 75, she's down to about 14 or so. FWIW, Dutch.

    1982 Datsun 4 cyl, 132,000. I get 33 mpg in town. Don't take it over the road much and it's too small to tow anything bigger than a 250 propane tank, made into a grill.

    I love burning diesal and looking into making my own.
