    Any of you guys that have a 2500HD with 8.1...........can you let me know how your mileage is? How about compared to a 6.0. I have a 6.0 and only get about 10-11 MPG.

    Thanks,
    Randy

    Depends on your plow, your lead foot, how you drive, etc. You should be happy with 8 mpg out of a hog that big, thats alot of cubes to feed. I have a 454 in a 3500hd and I get around 7. During our big storm 2 weeks ago, even my duramax, crew cab, 8 ft meyer, only averaged 8, but I was pushing 10 inches of snow.

    The best I have gotten is 13, all highway. The 5.4 fords are about the same as far as the people I have talked to. The dodges are even worse. A close friend has a dakota and the best he has gotten is 11. His brother has a hemi and gets about 8-10.

    You can get about 14 or so all highway with either a Ford 5.4 or 6.8.

    Damn! Thats horrendous... my 5.3L gets 15-16 around town and about 20 on the highway... but I get 13 when towing. My girlfriends grand cherokee gets about the same as mine, and its got the 4.0L quadra-trac awd.
     
  9. My 8.1L gets between 10.0-11.5 mixed city/hwy. Towing 6000lbs...I got 8.5mpg.

    With plow frame (not plow blade), 500lb balast, 285s (corrected) and no front valance, and cold weather I get 9-10mpg city.

    My worst was lots of plowing...6mpg.

    Do those who have the 8.1 wish you got the 6.0? In a few years or so im hoping to get a 3/4 and prolly wont have the funds for a diesel. Truck will be a daily driver, plow truck, and tow atvs around.
     
  11. No way on the 6.0L! For a couple MPG if that? I absolutely love my 8.1/Allison combo... From what I see 6.0L gets at most, a couple mpg better...still pretty poor aint it? I just assume have an abundance of power. I bought the truck expecting around 10mpg...and knowing it would do anything I needed w/o complaints.

    My 1500 with a 350 in it gets about 11mpg average right now. No plow, daily driven, and pulls trailers.

    The 8100 is awesome. I have three and a Duramax. Best I've gotten is 14+ on the highway on my '06 w/the 6 spd Ally. BUT, that same truck got about 6 plowing that last storm; but whattya expect going forward/back/fprward/back? I had the 6.0 in my '04 and you might bet 1-2 mpg better, but the power/torque more than makes up for it. NO regrets here. Too bad Chevy killed it for the new body style...

    8100 is by far the BEST gas motor i have owned. sucks on gas but boy does it haul a$$!!! never has any hesitation, and with the allison trans. attached it's a bulletproof couple. Love my truck and my motor.

    I've had lots of Chevy big block trucks over the years plus 1 6.5 detroit turbo diesel, 1 6.6 duramax, 2 6.0 Ford powerstrokes. All have been trucks I've towed10 K to 20K trailers with up and down the east coast. Lone Cowboy-- ya gotta agree with me on one thing.
    If you want to tow--get a diesel. If ya want to tow fast- get a big block. Diesels are hard to justify if you aren't gonna run them forever or at least 200K miles to get your investment back out. Big block are what --A $1,000 option at most usually and just look at how big of a smile they put on your face when you mash the go pedal!:D : :D :D :)

    I dunno
    most diesels will smoke most stock big blocks
    towing or not. (esp towing)

    The 6.6 LBZ duramax makes like 600ft-lbs of torque
    I think the 8100 makes like 400 or so? (not sure, feel free to correct me)

    that's muscle
    but yeah, if you tow all the time, gotta go diesel.

    Off the line, a stock big block will eat a stock diesel every time. Once that turbo spools up, it may catch it, but diesels are slow until then. The Dmax is easier to mod and you get greater gains for your buck and they are awesome to pull with. The fuel economy is way better too. For driveability and that sh!t eatin' grin you can't get off your face, the 8100 is king. The 8.1 is about $6K cheaper. You can buy a lotta fuel with that...

    I would go for the 8.1 every time. Roughly the same economy, way more power and a better transmission. Personally I can't stand the 6.0, I've driven quite a few of them and found them to be dogs. I've passed on quite a few trucks I've looked at just because of the 6.0. Been tempted a few times because they are cheaper, dime a dozen now, but just completely nutless. I don't know where Chevy came up with the 300 hp figure, I find it difficult to believe.
