6.0 engine MPG

[wannabemowing]

I was looking at a GMC 2500 with the 6.0 in it and I was wondering what people get that have these for MPG? Looking for MPG numbers for city driving, highway, pulling, and plowing. Thanks in advance for the info!!

[LawnTamer]

I have a '04 2500HD Ext. cab 4x4 longbed. I get just over 10mgp city driving. I am nearly always towing, or carrying 3,000-4,000lbs in the bed (fert tank). I have taken it on one midrange road trip, not towing anything and got just over 12 mpg. In the winter, just city driving, no towing, no plowing, I get a very consistent 11mpg.

[TimsLawnCareVA]

Local Chevy dealer let me test a 07 2500 reg cab long bed for a week last summer and it got around 10 pulling my trailer. I gave it back and bought a 00 F250 with a Powerstroke and am getting 15-17 mpg.

[wannabemowing]

I didn't realize they get such low MPG but that dosen't really surprise me, anybody have the V10 in a dodge or ford? what mpg's do you get. I would like to get a 3/4 ton so I could put a plow on the front without beating up the truck like it would to a 1/2 ton. Maybe I will just have to go with a half ton for now since I can't afford much of a 3/4 ton especially with a diesel which I would love to have!

[DLCS]

My 07 Chevy gets around 9mpg average pulling a loaded 18' trailer. The 07 and up don't get as good mpg as the previous 6.0 engines.

[dura to the max]

mine gets 10 towing. 12 city. 15 highway. the v10 in the fords gets the at least the same but usually better plus more power.

F350 4x4 Crew Cab V10. Truck with 2 people weighs about 7400lbs, with the trailer about 11,500.

About 9 towing, almost entirely local with an insane amount of stops and starts. Occasionally a good tank in the high 9's, occasionally a bad one in the mid 8's.

About 11 with no trailer, around town. Only time I ever do this kind of driving is in the winter.

And about 14 on the open highway, no trailer, with speed below 65.

[nick858]

00 F250 ext cab V10
8-9 towing 6k
9-10 driving
maybe 12-13 highway

Also have an 04 F250 diesel, a little better.
11 towing
14 driving
17 highway

[corey4671]

04 2500 4x4 ext cab short bed. 4.10 rear end pulling 18 open trailer getting around 9ish. just the truck with highway driving 14. tail wind downhill...14.

[zz4guy]

Wow the late models are getting the same mileage as my 16 year old 350 TBI engine with 250,000 miles on it.

You'd think that in 15 years they would have improved mileage somewhat, at least unloaded MPG.

If my engine ever goes I'll be buying a new engine, not a new truck.

[mike lane lawn care]

i'm lucky to get 12.5 city driving with a 50/50 mix of towing and unloaded.

[BillyRgn]

my 2000 gmc 2500 i get about 8 to 9 wich about 75 percent is towing a 16 ft double axle trailer with two lazers, as far as plowing, forget about it, with all the idling and a serious amount of pushing, i'd say i'm doing good if i get 5 mpg's, if i did a whole tank of highway i''d say i'd get about 12 mpg's

[MOWALLTHETIME]

I have an 04 2500 chevy crewcab 2wd and I see consistant 13-15 mpg in town towing a 16 plus 2ft dovetail trailer with a walker,gravely hydro walkbehind, 48"gravely zero turn plus honda commercial push mower with all the racks, trimmers, shovels blowers etc. I also tow my BOBCAT t300 or my kubota gst on a 20 ft equipment and I only see 9-10 with that load behind me. you have to look at the ratio of diesel mpg to cost vs gas mpg to cost. Say you get 17 mpg on diesel at 4.90 a gallon and you are paying 3.89 a gallon for regular gasoline for it to be the same operating cost your gas engine needs to get at least 13.5 miles per gallon. realistically I would figure 15mpg for diesel your gas engine needs to get 11.9mpg to be cost equal. Once you factor in maintaince and oil changes and greater initial cost, you can see that unless your diesel is hauling huge loads it actually costs you more to operate. I know ALL THE DIESEL GUYS ARE GOING TO ROAST ME BUT YOU HAVE TO LOOK AT THE ACTUAL COST OF OPERATION TO DETERMINE WHICH IS MORE EFFECIENT FOR YOUR BUSINESS. Do not get me wrong diesels pull like an demon and will lasts if you take care of them and drive them like a diesel truck needs to be driven. But if all you diesel guys would make your own biodesiel you could avg cost per gallon at 1.31 and your engines will run quiter, burn cleaner and last longer. as soon as I can afford to buy another truck I am going buy a diesel because I make biodesiel for my bobncat and tractor already. Here is a quote that all people need to realize and follow religously. "If your ship has not come in start swimming"

yeah,ford all the way,when will they learn?

[mx495]

07 2500HD 4x4 Extended Cab Classic short bed 6.0 4.10 gears.
11.5 mpg @ 75mph of the highway, 8.5 towing an 18 ft. enclosed trailer w/Ferris walk behind, ztr, trimmers, tools, lots of extra stuff, etc.

Chevy or Ford, whatever. I'm not brand loyal, they all suck and just have to have them to work. Why are people so brand loyal? A lot of people defend one brand or the other, you didn't build it or design it, you just bought it.

[procut]

'06 Chevy 2500HD 6.0, 4:10 axle, 4x4, about 8-10 pulling a 16' open trailer with a 60" ZTR, 36" WB and 21"

I was quite dissapointed in the milage. I knew the thing would suck gas, but 8mpg?!? I don't drive aggressive or do exesive ideling either. My '95 with a 350 V8 4x4 will get 10-12. Kind of makes me wonder.

[mx495]

procut-I agree, I drive easy and thought buying a new truck I would get better mileage.

i agree my 1995 GMC 3500 single rear wheel pick up has a 350 tbi injection, and it gets the same mpg's as my 2000 2500 pick up with the 6.0

05 2500HD excab longbox = shitty mpg

[GravelyNut]

As has been discussed to death on the Chevy truck forums, same gas mileage as the 8.1L with less guts for pulling.

Much more stringent emission standards. In 03 they had to reduce combustion chamber sizes to reduce them. Very similar things are happening with the new diesels

WOW. I've never driven a truck with the 8.1, but I can't imagine a gasser having more torque than that 6.0!

[BillyRgn]

the 8.1 has the allison transmission, so thats why it gets the same miles per gallon as the 6.0. if they put the allison on the 6.0, then that would be a hell of a truck, and would get better mpg's

[BillyRgn]

WOW. I've never driven a truck with the 8.1, but I can't imagine a gasser having more torque than that 6.0!

the 6.0 in discussion is the base V-8 gas engine that comes in the GMC / Chevy 2500 & 3500 trucks, the 8.1 V-8 gas engine is a big block that is an option engine for the GMC / Chevy 2500 & 3500 trucks. the 8.1 also comes with the same Allison transmission that also comes with the other engine option, the 6.6 Duramax Diesel.

[Petr51488]

yeah,ford all the way,when will they learn?

Last time i checked it had nothing to do with chevy vs ford. A diesel will allways get better mpg that its gas brother.

Mileage is the same, but the 6.0 has 90 more horsepower and pulls a lot harder than a TBI 350.

You beat me to it^^^^^^. Same mpg's more HP.....:usflag:

A 6.0 equipted truck with an Allison would not get better mileage than the same truck with the regular automatic. In fact, it would likely get worse. There is a weight penalty with the Allison. It weighs about 1000 lbs. Most automatics only weigh about half that. I think the reason the 8.1 gets the same or better MPG compared to the 6.0 is the fact that it is a more efficient engine in the RPM/load range that the engines run at. The 6.0 is a high RPM engine while the 8.1 is a mid range. With 4.10 gears and stock rims and tires, the 8.1 is nearing peak torque at 75 MPH in high gear. The 6.0 has further to go and the Duramax has already passed it. That's why the Diesels have 3.73:1 rear gears instead of 4.10s.

ok, i just did a mileage run. i went on the highway, half downhill, the other half uphill, cruise control set at 58 MPH, i was averaging 18.2 MPG until i hit the stop and go city traffic, which brought me down to an overall average of 17.4 MPG. and this was on a 45 mile drive. so i'm really pleased that the 6.0 is capable of some decent highway mileage

That isn't bad, what back axle ratio do you have?

[mike lane lawn care]

4.10, which is why i am surprised at the numbers.

[Lil'MowinMan93]

Go to fueleconomy.gov and on the right hand side it says like 82-2008 mpg click on it and then fill it out

I hope you weren't relying on the DIC for that info. They're known to read higher than what the fillup/drive/fillup info will give you. Like about 75%-85% of the DIC MPG would be closer to the true MPG.

what the heck kind of truck were you driving, was it a denali ??? or an SS with the H/O 6.0, because i have babied my 2000 gmc 2500 with the 6.0 and the 3:73 ratio doing like all high way and the most i ever came close to was an average of 12 mpg's

no, she is a 2500HD with the 4.10:1 ratio and 6.0L, the i heard the 2004-up got better fuel economy than the older ones.

that would only be good for anything smaller than a 3/4 ton though.

[Rons Rightway Lawncare]

It is not a 6.0 Chevy, but my 2008 Toyota Tundra Doublecab, with the 5.7 V-8 and 6 speed tranny gets pretty good milage.

I filled my truck up last friday night, I did a hair under 260 miles since last Friday night , used the truck to tow the boat ( with jet ski on the tongue of the boat trailer ) to the lake both on Saturday and Sunday ( about 35 miles total ) and then hooked up my 7x16 foot enclosed trailer. The trailer has a 61 inch Scag ZTR, a Husky 42 inch ZTR, Four full 5 gallon gas jugs, two trimmers, a edger, a blower, chainsaw, hedge trimmer, toolbox, hand tools, backpack sprayer, water cooler, steel shelves inside etc... Filled up a hour or two ago when I got done with work and averaged my mpg and she got 11.32 mpg. This is all stop and go city towing, and all of the miles was towing. The worst I have gotten so far has been a little over 10 mpg towing the enclosed trailer. I do some sitting in the truck with the engine idling while I eat lunch or wait in line at the drivethru, but not a excessive amount of idling.

The Toyota has been a extremely impressive truck so far ( I have about 6000 miles on it so far )

I have not driven it much without a trailer of some sorts in tow. The one time I drove it fairly far ( about 180 miles or so ) without a trailer was when I drove it to the mountains to pick up a motorcycle. I drove half of the trip empty and at around 65-75 mph, and the other half with a street bike in the bed of the truck and going slower, roughly 60-65 mph. The truck got right close to 20 mpg on that trip.

[wannabemowing]

Do any of you guys have intake and/or exhaust on your truck? If so did that help at all with gas mileage? I was hoping that maybe those two add-ons would give the MPG's a boost. Is there anything you can do to bump up the gas mileage, I'm talking add-on and stuff cause I know being easy on the gas helps too!!

[DieselOnly]

Our '07 Silverado Classic 1500 crew cab, 4X4, 4.10 with 6.0 MAX averages 13.5-17 MPG overall city/highway, empty/towing driving.

My '94 K1500 Silverado extended cab 3.73 with 6.5 turbocharged Diesel averages 15-18 MPG overall city/highway, empty/hauling driving.

The difference: '07 uses $3.999/gallon fuel and '94 uses $4.859/gallon fuel. Mileage is almost exactly the same.

[mx495]

Our '07 Silverado Classic 1500 crew cab, 4X4, 4.10 with 6.0 MAX averages 13.5-17 MPG overall city/highway, empty/towing driving.

I don't understand how the nearly identical truck can get such different mileage.
I have a 2007 2500hd Classic Ex. Cab 4x4 4.10 gears w/6.0 Liter and get 8.5 towing, 11.5-12 highway empty.

[DieselOnly]

MAX supposedly has Active Fuel Management. Shuts down 1/2 of the cylinders when cruising empty. I'm shure it has it, as it makes a different sound once cruising. That may be the difference. As far as I know, the MAX is not available in 3/4 tons and bigger.

[farmboy52787]

I didn't realize they get such low MPG but that dosen't really surprise me, anybody have the V10 in a dodge or ford? what mpg's do you get. I would like to get a 3/4 ton so I could put a plow on the front without beating up the truck like it would to a 1/2 ton. Maybe I will just have to go with a half ton for now since I can't afford much of a 3/4 ton especially with a diesel which I would love to have!
There isnt much of a price difference in Work Trucks for 2500 and 3500's, go with a 3500 with a single rear wheel, frames are stronger, they can haul more weight and they'll last longer. I started with a ranger, then bought a Chevy 3500 Regular Cab and there hasnt been anything that has stopped it. I bought another one ton dump strictly for the business, so i can use my other one for personal/business. I think I'll buy nothing but one ton's for the rest of my life

[Tharrell]

Thought I'd chime in on this one.
My '07 GMC 2500HD Classic with the 6.0 gets 12 mpg hauling a trailer at about 3-3300 lbs. Tony

[BillyRgn]

if you went to a dealer, and priced two trucks, a 2500 reg cab long bed, and a 3500 reg cab long bed single rear wheel with the same engine and options, you might actually get a better price on the 3500 because the demand for the 2500's is greater, my next reg cab will be 3500, but a crew cab or an extended cab would have to be a 2500 because the long bed is just to long for the stuff i do, if gm starts offering a short bed on single rear wheel 3500's extended cab and crew cabs like ford does, sales would sky rocket, and you would see nothing but 3500's in my fleet

[farmboy52787]

Probably the same reason why ford makes like 1 and a quarter and 1 an a half tons but GM makes em big like they should be. Theres not that much of a difference in the short bed length compared to the long, what only 18 inches, I think i could deal with 18 inches

GM still doesnt make 3500 short beds??!! Good gosh! I woulda thought they would have those out by now...
