hey all looking at the chevy 2500 was wondering how hard on gas the 8.1 is and how much more powerfuul is it than the 6.0 ? thanks for the help.

Here is some quick math:
1 liter = ~60 cid.

So, you want to know how 'good' a 486 cid V-8 is on fuel?

Because I couldn't say for sure but I can tell you that when you step on the gas pedal of
something that has a 455 under the hood you can literally hear it sucking fuel.
No I'm not kidding.

Most folks who buy vehicles with them size engines are not concerned about fuel economy.

You want economy then stick to 5.0's (~300 cid's), once you get up to a 350 (6L) you're hurting,
my 30 gallon gas tank on my 5.9L doesn't last me a week, I'm lucky if I get 300 miles out of it.

A 5.0?
I used to get 14-15mpg trailered and 12-14 loaded, the 5.0 pulls just fine but everyone keeps wanting more power...
Frustrates me to tears but then I guess other people's sons and daughters keep the oil flowing with their blood.

You seem to really like 5l engines. Perhaps you will be happy to hear that ford is going to put a 5l on the next f150 (and mustang). It is called the coyote 5l, and it makes ~400 hp and ~400 ft lbs torque on the mustang (will probably be tuned down for the f150).

Owning a 2001 8.1 340 HP/455 lb-ft, don't believe all the bad you hear about fuel use. From empty to 17K it still gets 12 MPG, on the highway, at legal + speeds. But that is with 4.10 gears instead of the normal 3.73s. That change alone adds 2K lbs to the towing ability. As for comparing it to the 6.0, forget it. Apples to oranges as far as torque and the 6.0 doesn't have the Allison. Plus the 8.1 is a 250K BIF rated engine. Some produce up to 95 lb-ft more torque than some of the 6.0 engines, or about 1/4 more torque. In the hills, you'd notice it. The 8.1 will run 3200 RPM up a 5% grade at 65 MPH in 4th with a GCVW of 17K. The 6.0 would be more like 4500 RPM to get the power and at its max load maybe down in 3rd gear. And getting no better mileage.

PS Topsite, the GM Vortec 8100 is 496 cubic inches.;)

They are still available with medium trucks. They are cheap because not many people need that much power and don't go with a diesel.

the 4L80 is an awesome tranny.. Have yet to have one in the shop!

And the 6.0 is more than enough motor for a 3/4ton truck.. Atleast it is for me..

I have a 2001 2500 crew (1500HD) with the 6.0L and I towed my JD110TLB around with it for years ~10,000 lbs with trailer. Going up a steep hill you have floor it haha but other then that it worked fine. I still have it but the duramax does the towing now. Also the 4L80E is a great tranny, I dont know anyone personally that has had a problem.

I am glad I am not the only one that sees this!


And Btw, my 2002 2500hd 6.0 yanks around the T300 with the grapple and 80in(I think?) 4n1 on the 24ft deckover pretty good. I mean its no diesel, but its pretty decent.

You can watch the gas gauge move though, but imo you cant complain about that because in all honesty, you bought it knowing that it was goin to suck gas like a mofo so quit crying about it and put some dam gas in it and keep going!

Yeah jr remember that buddy of mine who's got the lifted 6.0 I told you about? I went ice fishin with him last week and we drove 100 miles total and we burned like 1/3 of a tank :dizzy:

My dad's 6.0 will pull our toy hauler with plenty of power, only problem is we fight overdrive when were on the freeway. 7.5 mpg though! :waving: Hell of a lot more power than a trash 5.4

I have 4 trucks with 6.0 engines. Always pulling and not a problem. I do fit overdrive but I keep it in tow haul and do well. I also have a dmax that is awesome but I think when I trade again, I will go back to gas everything. I would like to get an 8.1 but is GM making that in a truck for the 2010-2011 yr? I will be looking at an 11 or 12 model year when trading again.

As far as milage - I do watch it but yet don't cuz that is not my concern - I need the truck, the power and were off.

In compared to fords - I don't like ours - not enough power until you about red line the thing - and then were off. Dodge - i am not running any newer styles right now so don't know.

The 8.1l gas won't be in anything that I know of next year.

Is that ford a 5.4? If so, what year? The pre 2004 ones were especially weak.

They wont be in the new trucks, I believe 07 was the lat year for the 8.1 and it was only in the classic body style. I have an 8.1 and love it. I get 10- 12 with mixed driving. It has the lower gears also. I love the Allison. I want to find the same truck with lower miles and an 2007. Mine is a 2003.

Yeah 6.0's can do alot of work. But if you found a good deal on the big block I would go for it. But usually those big engines are for people whoe are constantly pulling heavy loads and just dont like diesel

8.1 was by far the best gas motor out there I own two. If you ask me its like having a diesel but the fuel is a little cheaper. Im actually going to an auction on wednesday and I will probably pick up 2 or 3 from a business that went under.

company i worked for we had two newer one tons one with a 6.0 and other 8.1 , and both trucks where spec'd about the same , both where loaded down the same for winter plowing with a 2/3 yd sander and a 9 foot plow , and the 8.1 would get better mpg on avg... it wasnt much but it was better....

as far as a 5.4 ford :nono: gut less is what they are , my father works for the local water dept , and they orderd i think 3 or 4 a couple years ago , he said on avg they only get 7mpgs out of them towing ....

That's one reason I can't understand why GM killed it. With the 6.0 and an 8.1 loaded the same, you'll get as good or better mileage out of the 8.1. And you might get there quicker as the torque will launch it better. But if you're going to use your truck as a car, then the 6.0 wins.

If I were you, I would look for a 2001 - 2004 Duramax. I have a 2004.5 with the Dmax and I get 15mpg pulling the lawn trailer and about 11/11.5 pulling the Bobcat 853. I just put a Banks cold air intake and a 4" exhaust on it and my unloaded highway driving bumped up to 23mpg. Skip the gas burners and go for the diesel. It will not only serve you better, but they will hold their value better. I even put a 52 gallon tank on my truck so now I can go about 1000 miles on a road trip! All I need now is a programer to gain a little bit more. Just my 2 cents.

I found my diesel with 70K on the clock for $26K OTD. Of course I did buy it early in 2008 when diesel was just starting to climb. I think at one point I payed $5.05/gallon...but I still paid about the same month for fuel vs. my old gas burner. There is a big difference in mpg and power.

01-17-2010, 07:48 PM
I owned 2 of them. Average mileage was between 10 and 12 mpg. With the allison transmission, they can pull about anything. If you can find one with low miles, they are worth he investment. Just keep in mind that you can "put your foot in it" and drop your mileage to about 5 or 6.

How could he use a dump trailer for grass collection? Assuming that he isn't lying about doing small mulch jobs and grass collection only, then the dump trailer would be a stupid idea.

I thought it was just for leaf debris, mulch, and dirt, I didn't realize grass clippings. You can use your toneau cover to cover up the stuff in the truck when driving and it won't blow out and then you go to the dump and with the load handler, you crank the stuff out of the bed.

Funny thing about that is there were 3 trucks other than semis pulled over on the side, a kodiak (hood down and behind an F150), that F1shtty with the kodiak, the F1shtty with its hood up and an old f2shtty or f3shtty also with it's hood up.

I've seen lots of these videos, just watched one earlier today of a truck goin up Monteagle and then goin down. I'm not sure on the distance up Monteagle but it's a 5% grade, I handled 'er last winter, no problem, I was with my dad in his 6.0, we held 60 mph (with no load) and she never shifted down. I don't need to question my truck climbing a grade because that's what it's built for. Granted it was winter, but still, they're built to handle climbs.
